+NEWS - OpenPrinting CUPS Filters v1.28.16 - 2022-08-24
+------------------------------------------------------
+
+CHANGES IN V1.28.16
+
+ - imagetoraster, imagetopdf, libcupsfilters: Added support for
+ reading the resolution of an image from its EXIF data when
+ loading it. This way we get the image reproduced in its
+ original size with "print-scaling=none" (Issue #362).
+ - libcupsfilters: Replaced deprecated data types uint16 and
+ uint32. The function to read TIFF image files via libtiff in
+ cupsfilters/image-tiff.c uses the deprecated types uint16
+ and uint32. The replacements for these types are uint16_t
+ and uint32_t.
+
+CHANGES IN V1.28.15
+
+ - pdftops: In pdftops identify old LaserJets more precisely
+ for working around PostScript interpreter bugs, older
+ printers need Poppler, newer models need Ghostscript
+ (Ubuntu bug #1967816).
+
+CHANGES IN V1.28.14
+
+ - pdftopdf: Correct the output when suppressing auto-rotation
+ (option "nopdfAutoRotate"). Depending on the situation pages
+ got cropped in the wrong orientation or de-centered.
+ - pdftopdf: Correct the output when the
+ "orientation-requested" or the "landscape" option is
+ supplied. Output could be de-centered (Issue #456),
+ portrait-oriented pages be wrongly cropped and division of
+ the output page into cells for N-up done in the wrong
+ orientation.
+ - rastertopdf: In PCLm output mode the filter failed to
+ generate PCLm if the printer has no
+ "pclm-source-resolution-default" IPP attribute.
+
+CHANGES IN V1.28.13
+
+ - pdftopdf: Fix N-up printing when paper is taken
+ long-edge-first by the printer.
+ - pdftopdf: Fix cropping ("print-scaling=none" and
+ "print-scaling=fill") when paper is taken long-edge-first by
+ the printer (Issue #454).
+ - pdftops: Use Poppler for all Apple LaserWriter models (Issue
+ #452).
+
+CHANGES IN V1.28.12
+
+ - imagetoraster, imagetopdf: Fixed comparison of the image
+ size with the page size for print-scaling=auto. The image
+ size in pixels was compared with the page size in PostScript
+ points (1/72 inch).
+ - imagetoraster, imagetopdf: Fixed the "print-scaling=none"
+ (crop-to-fit) mode, also use crop-to-fit always when
+ requested, do not fall back to fit-to-page when the image
+ size differs significantly from the page size (Issue #362).
+ - libcupsfilters: Changed the default PPI resolution for
+ images as input files from 128 to 200 (Pull request #446).
+ - implicitclass: Do not check availability of "gs" and
+ "pdftops" executables, instead, check by the presence of
+ "gstoraster" and "pdftoraster" filters whether we have
+ configured cups-filters for Ghostscript and/or Poppler use.
+ - libcupsfilters: In the PPD generator for the driverless
+ utility and cups-browsed add "*cupsFilter2: ..." lines for
+ all supported driverless data formats (PDF, Apple/PWG
+ Raster, PCLm), and add lines for legacy data formats (PCL,
+ PostScript) only if no driverless formats available.
+ - libcupsfilters: Always use encryption for ipps. RFC7472
+ requires that 'ipps' must be used over HTTPS, but the
+ driverless utility does not enforce encryption (Pull request
+ #433).
+ - serial: Add a 10-msec sleep and at the end add a tcdrain().
+ For some unknown reason, every printing file need sleep a
+ little time to make sure the serial printer receive data is
+ right (Pull request #431).
+ - libcupsfilters: Fix resolver functions for DNS-SD-based
+ URIs, to make resolve_uri() also work when DEVICE_URI env
+ variable is set and to make ippfind_based_uri_converter()
+ not re-direct stdin.
+ - pdftopdf: Set default for print-scaling to avoid "should
+ never happem" log messages and undefined behavior.
+ - pdftopdf: Fix orientation-requested = 0. Consider
+ this as automatic selection and not as error.
+ - pdftopdf: Fixed all combinations of print-scaling and
+ number-up for printers with asymmetric margins (top !=
+ bottom or left != right) and for input files containing
+ pages with different sizes and/or orientations. Fixes
+ backported from 2.x branch.
+ - pdftopdf: Add 2% tolerance for input size larger than output
+ page when "print-scaling=auto" or "print-scaling=auto-fit"
+ is used and too large input pages should be scaled, fitting
+ documents not. This prevents a random-looking behavior if
+ input and output page size seem to be equal, but in reality
+ there are slight differences between size dimensions.
+
+CHANGES IN V1.28.11
+
+ - libcupsfilters: Let PPD generator take default ColorModel
+ from printer (CUPS issue #277).
+ - Braille: In vectortopdf check inkscape version to call
+ inkscape with the correct command line (Issue #315, Pull
+ request #443).
+ - Build system: Make missing DejaVuSans.ttf non-fatal in
+ ./configure as the font is only needed for test programs,
+ not for actual use of cups-filters (Issue #411).
+ - libcupsfilters: In imagetoraster() fixed crash with SGray
+ (Issue #435).
+ - cups-browsed: Naming of local queues is matched to CUPS'
+ current naming of temporary queues (no leading or trailing
+ underscores), to avoid duplicates in print dialogs which
+ support CUPS' temporary queues.
+ - libcupsfilters: Make cupsRasterParseIPPOptions() work
+ correctly together with PPDs, by not parsing options
+ which are in the printer's PPD and using
+ ppdRasterInterpretPPD() when set_defaults = 1 is set.
+ Without PPD the function behaves as before (Issue #436).
+ - libcupsfilters: Let colord_get_profile_for_device_id() not
+ return empty file name, to avoid error messages in CUPS
+ error_log.
+ - foomatic-rip: Debug message was wrongly sent to stdout and
+ not to log (Issue #422).
+
+CHANGES IN V1.28.10
+
+ - Sample PPDs: Add borderless page size definitions to Generic
+ PDF Printer, HP Color LaserJet CM3530 MFP PDF, and Ricoh PDF
+ Printer PPD files.
+ - Sample PPDs: From the PDF PPD files removed the unneeded
+ "*cupsFilters2: ..." line. For CUPS it does not make any
+ difference.
+ - libcupsfilters: Fixed pdftopdf filter to correctly support
+ page ranges without upper limit, like "10-" (Pull request
+ #399).
+ - libcupsfilters: Use wildcard tag (IPP_TAG_ZERO) search for
+ "media-type" and "media-type-supported" in the PPD
+ generator (Pull request #398).
+ - implicitclass, parallel: Added missing newlines at error
+ messages.
+ - libfontembed: Removed unneeded fontembed/main.c and ttfread
+ executable. Eliminates the dependency on DejaVuSans.ttf
+ (Issue #386).
+ - gstoraster: Refactor the filter a little to clarify handling
+ of page counts and set job-impressions for TotalPageCount in
+ PWG-Raster header (Pull request #394).
+ - cups-browsed: Make NotifLeaseDuration configurable and renew
+ after half the lease duration not 60 sec before end. The
+ early renewal improves reliability on busy systems a
+ lot. For easier development and debugging short durations
+ from 300 sec on can get selected (Pull request #378).
+
+CHANGES IN V1.28.9
+
+ - libcupsfilters: Silenced compiler warnings
+ - libcupsfilters: Removed duplicate code in the
+ apply_filters() function.
+ - driverless: If there are no driverless IPP printers
+ available let "driverless" terminate with exit code 0 and
+ not 1, to follow CUPS' standard of backends in discovery
+ mode terminating with 0 if there are no appropriate printers
+ found (Issue #375).
+ - gstoraster, foomatic-rip: Fixed Ghostscript command line for
+ counting pages as it took too long on PDFs from evince when
+ printing DjVu files (Issue #354, Pull request #371, Ubuntu
+ bug #1920730).
+ - cups-browsed: Renamed ldap_connect() due to conflict in
+ new openldap (Issue #367, Pull request #370).
+ - pdftoraster: Free color data after processing of each page
+ (Pull request #363).
+ - cups-browsed: Always save "...-default" option entries
+ from printers.conf, regardless of presence or absense
+ of PPD file (Pull request #359).
+ - cups-browsed: Start after network-online.target (Pull
+ request #360).
+ - texttopdf: Set default margins when no PPD file is used
+ (Pull request #356).
+
+CHANGES IN V1.28.8
+
+ - libcupsfilters: Made check whether the driverless PPD to
+ generate should be a fax out PPD more reliable (Issue #343).
+ - foomatic-rip: Options in the 5th command line argument of
+ the CUPS filter command line are separated only by white
+ space and not by comma, also make sure that an option "none"
+ is not considered a custom page size (Issue #348).
+ - implicitclass: Raise timeout for cups-browsed's answer from
+ 20s to 60s (Pull request #346).
+ - libcupsfilters: In the PPD generator really give priority to
+ Apple Raster against PDF (Issue #331).
+
+CHANGES IN V1.28.7
+
+ - driverless: Removed the support quality check from Pull
+ request #235 as it takes significant time for each printer
+ being listed, making cups-driverd (`lpinfo -m`) timing out
+ when there are many printers (OpenPrinting CUPS issue #65).
+ - libcupsfilters: In the PPD generator give priority to Apple
+ Raster against PDF (Issue #331).
+ - libcupsfilters: Added NULL check when removing ".Borderless"
+ suffixes from page size names (Issue #314, Pull request
+ #328).
+ - libcupsfilters: In the cupsRasterParseIPPOptions() map the
+ color spaces the same way as in the PPD generator (Issue
+ #326, Pull request #327).
+ - libcupsfilters: Fixed addition of grayscale mode in
+ generated PPD files, to avoid duplicate entries
+ (OpenPrinting CUPS issue #59).
+
+CHANGES IN V1.28.6
+
+ - libcupsfilters: In generated PPDs add a grayscale mode if
+ there are only color printing modes (from OpenPrinting
+ CUPS).
+ - libcupsfilters: In generated PPDs add an "OutputBin" option
+ also if it has only one choice (OpenPrinting CUPS pull
+ request #18).
+ - libcupsfilters: Generated PPDs could have an "Unknown"
+ default InputSlot (OpenPrinting CUPS issue #44).
+ - cups-browsed: Removed unneeded IPP attribute additions
+ preventing the created local queues from preserving a
+ location or description the user assigns to them (Issue
+ #323).
+ - cups-browsed: Removed all calls of the resolve_uri() function
+ of libcupsfilters, as these are not actually needed and in case
+ the supplied DNS-SD-based URI is not resolvable, the function
+ gets stuck for ~5 seconds.
+ - cups-browsed: Fixed several memory leaks, mainly from the
+ code to merge printer IPP attributes for clusters (Pull
+ request #322).
+ - cups-browsed: Silenced compiler warning.
+ - foomatic-rip: Fix infinite loop and input from file on raw
+ printing (Pull request #318).
+ - foomatic-rip: Remove temporary file created during pdf-to-ps
+ conversion (Pull request #313).
+
+CHANGES IN V1.28.5
+
+ - cups-browsed: UUID from IPP response was used after its
+ pointer was freed by ippDelete() (Pull request #311).
+
+CHANGES IN V1.28.4
+
+ - driverless: Avoid duplicate PPD list entries from the same
+ device via UUID
+ - driverless: Reduce ippfind calls by "driverless" and
+ "driverless-fax"called by CUPS. Let "driverless list" list
+ both print and fax PPDs and "driverless-fax list" do
+ nothing.
+ - driverless: Avoid duplicate listings in printer discovery,
+ by "driverless-fax" not listing any URI as "driverless"
+ lists them all already.
+ - driverless: Vastly improve performance by doing only one
+ ippfind call instead of two (IPP, IPPS) as ippfind accepts
+ more than one reg type on the command line.
+ - Sample PPDs: Corrected manufacturer name in
+ Fuji_Xerox-DocuPrint_CM305_df-PDF.ppd.
+
+CHANGES IN V1.28.3
+
+ - libcupsfilters, cups-browsed: Fixed inconsistency between
+ resolvers for DNS-SD-based URIs, resolve_uri() and
+ ippfind_based_uri_converter(). Now both return a freeable
+ string.
+ - libcupsfilters: Fix uninitialized buffer and parsing ippfind
+ output in ippfind_based_uri_converter() function (Issue
+ #308, Pull request #309).
+
+CHANGES IN V1.28.2
+
+ - driverless: Free allocated memory, use MAX_OUTPUT_LEN (Pull
+ request #304).
+ - driverless: Make the two ippfind tasks(for IPP
+ and IPPS) run in parallel (Pull request #302, #305, #306).
+ - braille: Support new liblouis tables not containing a
+ display name (Pull request #303)
+ - Build system: Let ./configure not error out when there is
+ more than one DejaVuSans.ttf test font candidate (Issue
+ #300).
+ - cups-browsed: Crash when a remote printer set as default
+ gets removed, due to missing variable in printf() call
+ (Issue #299).
+ - libcupsfilters: Removed all signal handling and global
+ variables from get_printer_attributes() and
+ ippfind_based_uri_converter(). This is overkill for these
+ quick operations and causes problems when shutting down
+ cups-browsed (Issue #298).
+
+CHANGES IN V1.28.1
+
+ - COPYING: Fixed several typos
+ - libcupsfilters: Fixed typo in log message of
+ get_printer_attributes functions.
+ - cups-browsed: Fixed typos in configuration file and man page
+ - libcupsfilters: Let the PPD generator not suffix page size
+ names with ".Borderless" if all page sizes would get this
+ suffix, for example for printers which generally print
+ borderless.
+ - libcupsfilters: Added "faxPrefix" option for generated IPP
+ Fax Out PPDs, so that this option also appears in print
+ dialogs.
+ - driverless: List addresses for local services correctly when
+ using "--std-ipp-uris" (with "localhost" hostname).
+ - driverless: Make calls of the ippfind utility somewhat faster,
+ setting the timeout of ippfind to automatic.
+ - libcupsfilters: Resolve DNS-SD-based URIs for local services
+ correctly (using hostname "localhost").
+ - libcupsfilters: In get_printer_attributes() functions do not
+ try to convert URIs which are not DNS-SD-based (Issue #294).
+ - libcupsfilters: In get_printer_attributes() functions also
+ support URIs with "dnssd://..." scheme.
+ - libcupsfilters: Moved signal handling back into main
+ function of the get_printer_attributes() variants, it got
+ moved out accidentally.
+ - driverless: For generating a PPD, independent whether via
+ "driverless URI" or "driverless cat URI", always allow CUPS
+ driver URIs (prefixed with "driverless: " or
+ "driverless-fax:") and pure IPP URIs.
+ - driverless: Accept clean IPP URIs also for 'driverless cat
+ ...' (Issue #295, Pull request #296).
+ - driverless-fax: Do not use fixed path for call of driverless
+ itself (Pull request #293).
+
+CHANGES IN V1.28.0
+
+ - driverless, driverless-fax, libcupsfilters: Added IPP Fax
+ Out support. Now printer setup tools list an additional fax
+ "driver". A fax queue is created by selecting this
+ driver. Jobs have to be sent with "-o phone=12345" to supply
+ the destination phone number (Pull request #280).
+ - libfontembed: Silenced warning with gcc 10.x (Pull request
+ #287).
+ - cups-browsed: Added ./configure options
+ --enable-saving-created-queues and
+ --with-remote-cups-local-queue-naming (Pull request: #253,
+ #285).
+ - cups-browsed: Fixed several memory leaks, mainly from the
+ code to merge printer IPP attributes for clusters (Pull
+ request #281, #283).
+ - driverless: Added "--std-ipp-uris" command line option to
+ show listed URIs in standard hostname-based form (not the
+ CUPS DNS-SD-service-name-based form. Only for manual call of
+ the utility, for debugging purposes (Pull request #277).
+ - libfontembed: Removed assert() calls which cause crashes
+ when unsupported emoji fonts are installed (Issue #254, Pull
+ request #276).
+ - driverless: Added support for IPPS (use "ipps://..." URIs if
+ possible, Issue #251, Pull request #270, #273).
+ - gstoraster, gstopdf: When converting PostScript to PDF use
+ the "pdfwrite" output device with "-dPDFSETTINGS=/default"
+ instead of with "-dPDFSETTINGS=/printer". This reproduces
+ bitmaps in the PostScript file with their original image
+ quality (Issue #272).
+ - cups-browsed: Limit log file size and add backup file for
+ previous log entries. Introduced the configuration option
+ DebugLogFileSize in cups-browsed.conf to set the actual
+ limit in kilobytes or 0 to get the old behavior of an
+ unlimited size for the log file (Issue #260, Pull request
+ #267).
+ - gstoraster, gstopdf: Do not apply margins when output format
+ is PDF, as then we convert an incoming PostScript file to
+ PDF (pre-pdftopdf) and do not prepare the pages for the
+ printer (post-pdftopdf, Issue #250).
+ - cups-browsed: Do not write any log messages directly to
+ stderr, there were some concerning timeouts on queue
+ creation (Issue #260).
+ - Build system: Fix cross-compilation without DejaVu test font
+ in configure.ac (Issue #262, Pull request #263).
+ - libcupsfilters: Respect the fact that PPD keywords
+ are case-sensitive when adding "*cupsManualCopies: True" in
+ PPD file (Issue #242).
+ - libcupsfilters: Older versions of libcups (< 2.3.1)
+ had the enum name for fold-accordion finishings mistyped.
+ Added a workaround.
+ - cups-browsed: Remove left-over local queues from the
+ previous session more quickly when CUPS legacy browsing is
+ turned on.
+ - cups-browsed: Left-over local queues from the previous
+ session for which the corresponding remote printer did not
+ appear again did not get removed as they were considered
+ externally overwritten.
+ - gstoraster, gstopdf: Add option "-dDoNumCopies" to
+ Ghostscript command line if we are outputting PDF (called
+ via gstopdf wrapper) and the number of copies supplied to
+ CUPS is 1 (4th command line argument). In this case we
+ convert incoming PostScript to PDF and need to respect
+ embedded PostScript commands to implement the number of
+ copies (Issue #255, CUPS Issue #5796, OpenSUSE bug
+ #1173345).
+ - imagetoraster: Potential null dereference fix (when no valid
+ PPD is supplied, Pull request #256).
+ - cups-browsed: Call cupsGetNamedDest() only if
+ "OnlyUnsupportedByCUPS No"
+ - Sample PPDs: Corrected ColorModel default for Generic PWG
+ Raster PPD to Color (Pull request #247).
+ - cups-browsed: Mark the temp queue as cups-browsed-generated
+ during setting printer-is-shared (Pull request #246).
+ - cups-browsed: Remove mentions of README and AUTHORS files in
+ the man page (Pull request #244).
+ - pclmtoraster: Added new filter to extract Raster data from
+ raster-only PDF files, here for the special case of PCLm
+ files (Pull request #243, #257).
+ - Sample PPDs: In Generic-PDF_Printer-PDF.ppd add option to
+ switch between color and grayscale printing (Pull request
+ #237).
+
+CHANGES IN V1.27.5
+
+ - cups-browsed: Do not remove the created local queues on
+ shutdown, to avoid their re-creation on restart, so that
+ desktops get no cluttered with notifications of new queues
+ being created. One can return to the old behavior via
+ "KeepGeneratedQueuesOnShutdown No" in cups-browsed.conf
+ (Ubuntu bug #1869981, #1878241).
+ - cups-browsed: Do not accept DNS-SD broadcasts of IPPS type
+ of "remote" CUPS queues of another CUPS instance on the
+ local machine. This way we get a local queue pointing to
+ such a printer only in unencrypted version (IPP). For some
+ reason printing from one CUPS server to another on the same
+ machine works only unencrypted.
+ - foomatic-rip: Map two-sided-short-edge to DuplexTumble (Pull
+ request #236)
+ - Build system: In configure.ac use AS_IF instead of
+ AC_CHECK_FILE for font check (Issue #239, Pull request #240)
+ - cups-browsed: Cleaned up code for determining to which CUPS
+ server (host/port/domain socket) to connect, so that
+ connection via DomainSocket cups-browsed.conf directive,
+ CUPS_SERVER and IPP_PORT environment variables and all
+ defaults and methods of libcups, including CUPS' client.conf
+ work.
+ - gstoraster, rastertopdf: Do not pass NULL to fprintf() (Pull
+ request #230).
+ - libcupsfilters: Silence compiler warning (Pull request #229).
+
+CHANGES IN V1.27.4
+
+ - libcupsfilters, cups-browsed: Fix memory issues in
+ ppdgenerator and cups-browsed (Pull request #226).
+ - pdftops: Mention cups-filters README, CUPS README in debug
+ log (Pull request #225).
+ - pdftopdf, gstoraster, foomatic-rip: Use "-dSAFER"
+ Ghostscript option, instead of the deprecated
+ "-dPARANOIDSAFER" (Pull request #224).
+ - Build System: Replace '==' in configure.ac test with '=', as
+ the former is a bashism (Pull request #222).
+
+CHANGES IN V1.27.3
+
+ - cups-browsed: Allow sharing local queues pointing to remote
+ CUPS queues and re-sharing printers discovered via
+ BrowsePoll by default, using
+ AllowResharingRemoteCUPSPrinters and
+ NewBrowsePollQueuesShared directives in cups-browsed.conf
+ (Issue #101, Pull request #218).
+ - driverless: Correctly unlink temporary file when generating
+ PPD file (Pull request #220).
+ - cups-browsed: Fixed memory leaks (Pull request #219).
+ - foomatic-rip: PDF page count side-loads the PDF file to
+ count the pages in, so it cannot be run in -dSAFER mode. Run
+ even in -dNOSAFER mode to override the -dSAFER default of
+ newer Ghostscript versions. This should not cause a security
+ problem as we do not take an input file which could do
+ arbitrary side-loads but we run hard-coded PostScript
+ commands instead (Issue #216).
+ - libfontembed: Add checks to the test programs to not
+ segfault if the test font file is not found (Pull request
+ #214).
+ - Build System: Let ./configure fail if the supplied test font
+ file path (or the default) does not exist (Pull request
+ #214), also use the "find" command to find the test font
+ file DejaVuSans.ttf under /usr/share/fonts, as every
+ distribution has it somewhere else.
+
+CHANGES IN V1.27.2
+
+ - foomatic-rip: In some PostScript input files it was possible
+ that option settings did not get inserted or lines inserted
+ on the wron place (Issue #208, Pull request #210).
+ - foomatic-rip: For the PDF page count call Ghostscript in
+ sandbox mode and fix pointer arithmetics (Pull request
+ #212).
+ - foomatic-rip: Zero-page-job handling changes made the last
+ page of PostScript files not printed, also turning one-page
+ jobs into zero-page jobs (Issue #200, Issue #206, Issue
+ #208, Pull request #209, Pull request #210, Pull request
+ #211).
+ - cups-browsed: check_printer_with_option() function:
+ Initialize the value, add further checks, freeing memory and
+ stop allocating magic numbers (Pull request #204).
+ - cups-browsed: Additional checks against crashes in the
+ is_local_hostname() function (Ubuntu bug #1863716)
+
+CHANGES IN V1.27.1
+
+ - libcupsfilters: Let the PPD generator not put any dashes
+ into the PPD option and choice names when translating them
+ from IPP attribute names, to avoid that on the
+ back-translation by CUPS no double-dashes are
+ generated. This broke paper tray selections with tray names
+ like "tray-1", "tray-2", ... (Issue #192, Issue #201, Debian
+ bug #949315).
+ - foomatic-rip: Fixed segfault when PRINTER environment
+ variable is not supplied.
+ - pdftopdf, pdftops, gstoraster, gstopdf, gstopxl,
+ rastertoescpx, rastertopclx, foomatic-rip: Handle zero-page
+ jobs (Issue #117, Pull request #196, Pull request #197, Pull
+ request #198, Pull request #200).
+ - texttopdf: Added support for CJK (double-width) fonts (Issue
+ #135, Pull request #199).
+ - cups-browsed: Switched default for "CreateIPPPrinterQueues"
+ from "local-only" to "All". The configure script options
+ "--enable-auto-setup-local-only" and
+ "--enable-auto-setup-driverless-only" can be used to change
+ this default (Debian bug #921252).
+ - rastertoescpx: Fixed wrong freeing of a buffer.
+ - pdftops: Added options "crop-to-fit" and "fill" to the
+ pdftopdf options which the pstops called by pdftops should
+ not apply a second time.
+ - pdftops: Added missing "-sstdout=%stderr" to Ghostscript
+ command line, to assure that all messages are redirected to
+ stderr and do not mix up with the output data.
+
+CHANGES IN V1.27.0
+
+ - cups-browsed: Eliminate the use of the local CUPS daemon's
+ (the CUPS we are attached to) port number completely, so
+ that for attaching to an arbitrary local CUPS daemon
+ listening on an arbitrary port (or even not listening on
+ localhost at all) it is enough to tell cups-browsed the
+ domain socket the CUPS daemon is listening on.
+ - cups-browsed, libcupsfilters: Identify DNS-SD-reported
+ printers as of the local CUPS daemon via UUID and not via
+ the port on which the local CUPS is listening, as we do not
+ always have this port available.
+ - cups-browsed: Leave the port for legacy CUPS browsing and
+ broadcasting on 631, do not use a possible alternative port
+ of the CUPS we are attached to. The legacy CUPS servers we
+ communicate with are always remote ones.
+ - libcupsfilters: in the PPD generator prioritize
+ print-color-mode-supported against
+ pwg-raster-document-type-supported (Issue #186, Pull request
+ #188)
+ - rastertopdf, rastertops, texttopdf, pdftoraster,
+ mupdftoraster: Handle zero-page jobs, corrections on
+ zero-page job handling (Issue #117)
+ - cups-browsed: When restarting after a crash make sure that
+ local queue names have same upper/lower case as before.
+ - cups-browsed: Small code improvements to reduce crash
+ probability.
+
+CHANGES IN V1.26.2
+
+ - cups-browsed: Added crash guards to avoid crashes in case
+ the dummy printer entry for a deleted master entry is used.
+ - cups-browsed: Set the port of the local CUPS daemon to be
+ used according to the IPP_PORT environment variable.
+ - cups-browsed: Eliminated the use of the cupsGetPPD2()
+ function of libcups completely, also the remaining calls
+ in the record_printer_options() and update_cups_queues()
+ functions, the former causing incomplete recording of
+ option settings and the latter use of CUPS-generated
+ PPDs not working when CUPS is running on a non-standard
+ port.
+ - cups-browsed: Eliminated the use of the cupsGetPPD2()
+ function of libcups in queue_overwritten(). The function
+ actually loads the queue's PPD file if the queue is on a
+ local CUPS on port 631. Due to a bug the function fails if
+ an alternative port is used. This lets queue_overwritten()
+ always assume that the PPD got removed and therefore the
+ queue got overwritten. So queues got released from
+ cups-browsed if it was printed on them or if they were
+ supposed to be removed on shutdown.
+ - foomatic-rip: Fixed compilation with -fno-common. Starting
+ from the upcoming GCC 10, the default of the -fcommon option
+ will change to -fno-common. This causes compilation errors
+ in foomatic-rip due to missing "external" declarations.
+ (Pull request #184).
+
+CHANGES IN V1.26.1
+
+ - build system: Install the "implicitclass" backend with
+ "-rwx------" permissions, so that CUPS executes it as root,
+ as the "ipp" CUPS backend also has to be executed as root
+ (Issue #183).
+ - build system: Fixed setting permissions when installing the
+ "cups-brf" backend.
+ - libcupsfilters: When using the
+ "media-{bottom,left,right,top}-margin-supported" IPP
+ attributes (needed if we have no "media-col-database"), use
+ the minimum and not the maximum margins, this allows
+ accessing more of the printer's capabilities, especially for
+ legacy printers which do not provide sufficient information
+ (Issue #22).
+
+CHANGES IN V1.26.0
+
+ - cups-browsed: When generating local queues for printers for
+ which the local CUPS daemon would provide temporary queues
+ use the PPDs generated by libcupsfilters and not the ones
+ generated by CUPS. The PPD generation of libcupsfilters also
+ works with IPP-1.x-only printers, printers which do not
+ support to query "media-col-database" and printers which
+ support driverless printing only via PCLm. This can be
+ changed via the "UseCUPSGeneratedPPDs" directive in
+ cups-browsed.conf (Issue #22).
+ - libcupsfilters: Re-structured the get_printer_attributes()
+ function to remove the recursive calls for the fallbacks, to
+ check required attributes in the response only if requested,
+ and to fully integrate the method of getting a suitable
+ response for a full printer capability list also if the
+ printer is only IPP 1.1 or does not support the
+ "media-col-database" attribute (Issue #22, Issue #163).
+ - libcupsfilters, cups-browsed, driverless: Moved the funtions
+ get_printer_attributes() and resolve_uri() from cups-browsed
+ into libcupsfilters, to share them with the driverless
+ utility (Issue #22).
+ - implicitclass: Fixed wrong stdout redirection from the
+ filters to the IPP backend and hard-coded path for "ipp"
+ backend call (Possible fix for Issue #163, Issue #181).
+ - cups-browsed, driverless: Use DNS-SD-service-name-based URIs
+ instead of host-name-based ones, as CUPS also does. In
+ cups-browsed one can switch back to the conventional
+ host-name-based URIs via the new "DNSSDBasedDeviceURIs"
+ configuration option. Note that cups-browsed always uses
+ conventional URIs for printers discovered via legacy CUPS
+ browsing or LDAP.
+ - cups-browsed: When removing a CUPS queue, do not consider an
+ error (and retry) if the queue does not actually exist. Also
+ ignore errors when checking whether there are still
+ jobs. This way when a new queue gets created and the
+ generation of the PPD file fails the attempt to remove this
+ non-existing queueu when removing the printer entry does not
+ cause any problem.
+ - cups-browsed: Improved the fallback mechanism of the
+ get_printer_attributes() function. Instead of considering
+ the request failed by the content of the response only when
+ not more than the two language atrributes come out, we check
+ through a list of required attributes whether they are all
+ there. In addition, we actually fail when all callbacks
+ have failed (Issue #22).
+ - cups-browsed: Introduced new configuration options
+ "UpdateCUPSQueuesMaxPerCall" and
+ "PauseBetweenCUPSQueueUpdates" to limit the amount of local
+ CUPS queues created, modified, or removed in a single event
+ callback. Before, when there were thousands of printers in
+ the network, cups-browsed got blocked for other tasks, like
+ assigning a destination printer for a cluster print job
+ (Issue #163).
+
+CHANGES IN V1.25.13
+
+ - implicitclass: When passing on the job via the "ipp" CUPS
+ backend, set argv[0] to the destination printer URI (Pull
+ request #173).
+ - cups-browsed: Added another fallback to the
+ get-printer-attributes IPP request: Now after failing the
+ standard request ("all", "media-col-database") with both IPP
+ 2.0 and IPP 1.1, try simply "all", without
+ "media-col-database" (Pull request #173).
+ - cups-browsed: Do not set printer-is-shared for remote CUPS
+ queue when making a temporary queue permanent (Pull request
+ #180).
+ - cups-browsed: Fix leaks of ipp_t struct and load balancing
+ on the servers (Pull request #179).
+ - cups-browsed, implicitclass: Prioritize Apple Raster against
+ PWG Raster when selecting the PDL for the destination
+ printer for a job sent to a cluster, also cleaned up the PDL
+ selector code and added PostScript support.
+ - libcupsfilters: Updated the PPD generator adding all changes
+ of the PPD generator of CUPS: Support for "job-account-id",
+ "job-accounting-user-id", "job-password", finishing options
+ "trim-..." added, finishing options and
+ "finishing-col-database" support synced with CUPS.
+ - libcupsfilters: In the PPD generator get the mode for
+ handling the back sides of the sheets when printing duplex
+ preferrably from the "urf-supported" attribute.
+ - libcupsfilters: Fixed bug that the PPD generator did not
+ output the "*CloseUI: *ColorModel" line when it did not
+ determine a default setting for "ColorModel".
+ - cups-browsed: Added some missing memory allocations leading
+ to a segfault (Issue #175).
+
+CHANGES IN V1.25.12
+
+ - libcupsfilters: Use the text names "Draft", "Normal", and
+ "High" instead of 3, 4, and 5 as choice names for the
+ "cupsPrintQuality" option as CUPS does (Issue #171).
+ - libcupsfilters: If a printer supports both Apple Raster and
+ PWG Raster let the generated PPD use Apple Raster as there
+ are several printers which report PWG Raster support but do
+ not actually print PWG Raster (Pull reguest #168, Issue
+ #171, CUPS issue #5238).
+ - cups-browsed: Fix unset location check to use DNS-SD field
+ (Pull request #172).
+ - libcupsfilters, beh, implicitclass, foomatic-rip,
+ imagetopdf, mupdftoraster, pdftops, sys5ippprinter,
+ cups-browsed, driverless: Silenced all compiler warnings to
+ make the build process of cups-filters completely free of
+ warnings.
+ - pdftops: Fixed crash when using filter without PPD file.
+ - pdftops: If printing grayscale jobs with Ghostscript as PDF
+ renderer, add "-sProcessColorModel=DeviceGray" to
+ Ghostscript command line.
+ - pdftops: Do not use the ugly "pdftops -level1 ..."
+ workaround to get grayscale PostScript output from
+ Poppler. It leads to huge output files with Poppler's
+ "pdftops" utility and does not work at all with
+ "pdftocairo". Poppler itself does not support PostScript
+ output converted to grayscale. Issue a warning with the hint
+ to use Ghostscript or MuPDF as PDF renderer (Issue #169).
+ - libcupsfilters: In the cupsRasterParseIPPOptions()
+ accept also "Mono", "Monochrome", and "Gray" as color
+ space names.
+
+CHANGES IN V1.25.11
+
+ - cups-browsed: Really accept entries without printer name
+ reported on a job status request (Issue #163).
+ - cups-browsed: Strip IPP attribute values reported by the
+ printer on a get-printer-attributes request from white
+ space (Pull request #166).
+
+CHANGES IN V1.25.10
+
+ - libcupsfilters: Added NULL checks when handling page size
+ names as some of the page sizes in CUPS' PWG media list have
+ a NULL PPD name (Ubuntu bug #1847488).
+
+CHANGES IN V1.25.9
+
+ - cups-browsed: Fix leaks in get_printer_attributes() function.
+ - cups-browsed: Avoid infinite recursion on IPP 1.1 fallback.
+
+CHANGES IN V1.25.8
+
+ - cups-browsed: On a job status request accept also entries
+ without the printer name being reported (Issue #163).
+ - cups-browsed: Fall back to IPP 1.1 if a
+ get-printer-attributes IPP request with IPP 2.x fails (Issue
+ #124, Issue #163).
+ - gstoraster: Use ".setfilladjust2" instead of the
+ undocumented ".setfilladjust" PostScript command for
+ Center-of-Pixel method to fill paths (Issue #164).
+
+CHANGES IN V1.25.7
+
+ - implicitclass, libcupsfilters: Fixes to solve an assertion
+ error and printing to an Apple Raster printer (Issue #162,
+ Ubuntu bug #1845286, Ubuntu bug #1845548).
+ - cups-browsed: Do not try to resolve the network interface
+ name on Avahi messages which are not interface-related (like
+ "All for now"or "Cache exhausted", Issue #163).
+ - Build system: The helper script ln-srf to build on systems
+ with old ln was not included in the release tarballs (Issue
+ #161).
+ - pdftoraster: Fixed some bugs in output bitmap generation (
+ writePageImage() function): Segfault on output of
+ up-side-down pages (back side when printing duplex on some
+ printers), margin offsets not taken into account on
+ monochrome jobs, CUPS_CSPACE_W color space not recognized as
+ monochrome (Ubuntu bug #1845286).
+
+CHANGES IN V1.25.6
+
+ - implicitclass: Make sure the destination printer gets always
+ set and do not pass on the cups-browsed-dest-printer when
+ sending the job to the final destination (Issue #152, Pull
+ request #159).
+ - Build system: Support old ln versions without the -r option
+ (Pull request #154, #157).
+ - texttotext: Link with libiconv if needed (Pull request
+ #155, #158).
+ - foomatic-rip: Fix argument representation for raw queue
+ debug mesaage (Pull request #153).
+
+CHANGES IN V1.25.5
+
+ - bannertopdf: Added missing "#include <cstring>" to pdf.cxx
+ so that bannertopdf correctly builds with QPDF 9.0.0 (Issue
+ #134, Issue #151, Gentoo bug #693498).
+ - rastertopdf: Let the getIPPColorProfileName() function not
+ return a pointer to a local variable (clang warning, Issue
+ #150).
+ - cups-browsed: If a locally generated queue (usually with
+ "implicitclass://..." URI) left over from a previous
+ (crashed) session is picked up on startup, do not set the
+ URI as the remote printer's URI and do not cause a fatal
+ error on a failed get-printer-attributes IPP request (Issue
+ #148, Debian bug #939316).
+ - pdftopdf: Do not preserve encryption, since the output
+ already goes into the printer (Issue #146, Pull request
+ #147).
+
+CHANGES IN V1.25.4
+
+ - imagetoraster: Do not call imagetops and pstoraster for
+ classifications and page labels as these filters are not
+ included any more with cups-filters. Classifications and
+ page labels are currently not supported for direct image
+ printing, only for PDF or PostScript input (which goes
+ through pdftopdf).
+ - imagetoraster, imagetopdf: Fixed auto-rotation of images to
+ fit output page best (Issue #145).
+ - pdftoraster: If the PPD contains several equally-sized page
+ size entries which match the size of the input page and one
+ is the size selected by the user via the "PageSize" or
+ "media" option (or the default selection in the PPD) then
+ prefer this one instead of simply the first matching one.
+ - pdftoraster: If the input page size cannot be matched with
+ one of the PPD's page sizes it is considered a custom size,
+ fill the page size name field of the CUPS Raster header with
+ "Custom.XXXxYYY" then.
+ - pdftoraster: Match the input page size with a page size in
+ the PPD only if the differences of the dimensions are less
+ than 1%, also match the input page size against the
+ imageable area of the PPD's page sizes if no match with the
+ full page size is found (Issue #138).
+
+CHANGES IN V1.25.3
+
+ - Sample PPDs: In HP-Color_LaserJet_CM3530_MFP-PDF.ppd renamed
+ "custom" choice of the option "stapleoption" to "customsize"
+ as from CUPS 2.2.12 on "custom" is not accepted any more as a
+ choice name in a PPD file.
+ - cups-browsed: Fixed check whether the remote printer understands
+ PWG Raster (Issue #141).
+
+CHANGES IN V1.25.2
+
+ - foomatic-rip: Fixed segmentation fault when running
+ foomatic-rip by hand and the PRINTER environment variable is
+ not set (Pull request #139).
+ - cups-browsed: Added note to cups-browsed.conf and man page
+ about IP-based URIs depending on the network interface used.
+ - cups-browsed: For each DNS-SD-discovered printer register
+ each DNS-SD discovery instance with network interface,
+ family, and IPP type. When DNS-SD messages of instances
+ disappearing show up, only unregister this instance and
+ remove the printer only if no instance is left. This
+ prevents a local queue of a still available printer being
+ removed when Wi-Fi (= one interface) is turned off (Issue
+ #136).
+ - cups-browsed: If a remote printer is served from the local
+ machine, prefer the "localhost"/loopback interface URI.
+ - cups-browsed: If a remote printer is discovered more than
+ once, use the new instance only if it has no downgrades and
+ at least one upgrade compared to the old one. Features
+ currently compared are IPP/IPPS, loopback interface or not,
+ and discovery via CUPS legacy/LDAP/DNS-SD.
+ - cups-browsed: If an Avahi-discovered entry comes through the
+ "lo" interface, always use the host name "localhost". Use
+ IP addresses instead of host names only if explicitly
+ requested.
+ - cups-browsed: Consider remote printer entries also as from
+ the same printer if one has the local machine's network name
+ and the other "localhost" as host name (Issue #136).
+
+CHANGES IN V1.25.1
+
+ - imagetopdf: Fixed crash when no PPD file was supplied (Pull
+ request #133).
+ - pdftoraster: Fixed offset issues leading to segmentation
+ faults (Issue #131, Pull request #132).
+ - pdftoraster: Added anti-aliasing for better raster image
+ quality (Pull request #129).
+ - pdftoraster: Added graceful handling of zero-page input
+ (Issue #117, Pull request #127).
+
+CHANGES IN V1.25.0
+
+ - pdftoijs, pdftoopvp: Removed these deprecated filters
+ completely as there is no demand for them any more. They
+ also used unstable, undocumented APIs of Poppler.
+ - pdftoraster: Changed from using unstable, undocumented APIs
+ of Poppler to stable, documented ones, to improve
+ maintainability of this filter, and with it of the
+ cups-filters package. Thanks to Tanmay Anand for
+ contributing this as his Google Summer of Code 2019 project.
+ - libcupsfilters: Added support for color spaces CMY and RGBW
+ when using filters without PPD file (mainly for development
+ and debugging, option "print-color-mode" with values
+ "cmy-XX" and "rgbw-XX" with XX being the number of bits per
+ color).
+
+CHANGES IN V1.24.0
+
+ - cups-browsed: Integration of Deepak Patankar's Google Summer
+ of Code 2018 project with the main goal of clustering
+ different printers and automatically selecting the
+ destination printers by job content and option/attribute
+ settings. All changes of this release are done by Deepak as
+ parts of his project.
+ - cups-browsed, implicitclass: Support for mixed clusters of
+ remote CUPS queues and IPP network printers. For this PPD
+ files of remote CUPS queues are generated by cups-browsed
+ based on IPP queries, as for native IPP printers, the number
+ of jobs for load balancing is polled in a way that it works
+ also with native IPP printers, the implicitclass backend
+ sends jobs directky to the printer instead of re-queueing
+ them via CUPS.
+ - cups-browsed: Merge IPP attributes of several printers to
+ combined attributes for the cluster to generate the
+ cluster's PPD file, including PPD constraints for option
+ combinations not fulfillable by any of the member printers,
+ and finding reasonable, non-conflicting default settings,
+ - cups-browsed: Selection algorithm for the destination
+ printer for a job sent to the cluster. Based on the job
+ settings requested such as page size, media type, print
+ quality, ... the best most suitable printer in the cluster
+ for the job will be selected.
+ - cups-browsed, implicitclass: Filter jobs to clusters already
+ locally. Due to the fact that a cluster's member printers
+ are not exclusively non-raw CUPS queues with the complete
+ filtering framework on the remote server, but also native
+ IPP printers, we need to support generic driverless printers
+ as destination. So we cannot pass on the input data
+ unfiltered but need to filter locally. We let the cluster's
+ PPD file emulate a PDF printer, letting the local CUPS queue
+ of the cluster run pdftopdf and any pre-filters to turn the
+ input into PDF and we let the implicitclass backend turn PDF
+ into a format understood by the destination printer,
+ supporting the 4 formats of driverless IPP printing: PDF,
+ PWG Raster, Apple Raster, PCLm.
+
+CHANGES IN V1.23.0
+
+ - pdftops, mupdftoraster: Let pdftops call mutool directly and
+ so that it directly outputs PostScript, eliminating the need
+ to call the mupdftoraster and rastertops filters.
+ - mupdftoraster: Reduced the use of temporary files from 3 to
+ just one.
+ - imagetopdf, imagetoraster, pdftopdf: Add support for
+ print-scaling option (Issue #108, Pull request #118).
+
+CHANGES IN V1.22.6
+
+ - rastertops: Fixed PageSize settings in the PostScript output
+ (Must be in points not in pixels).
+ - pdftops, mupdftoraster: Produce actual grayscale/monochrome
+ PostScript (and not only instructions to print grayscale/
+ monochrome) for jobs to be printed in grayscale/monochrome
+ (Issue #96, Pull request #115).
+ - mupdftoraster: Fixed filter not producing output at all.
+ - Build system: ENABLE_DRIVERLESS got only defined with CUPS
+ 1.6 and newer, not with older CUPS versions (Issue #111).
+ - pdftopdf, imagetopdf, imagetoraster: Silenced compiler
+ warnings.
+ - cups-browsed, driverless: Replaced httpConnect() calls by
+ httpConnect2() calls as the former CUPS library function is
+ deprecated.
+ - Build system: Compile everything using the CUPS libraries
+ with '-D_PPD_DEPRECATED=""' for the time being until the
+ deprecated PPD API calls get replaced, to stop the flooding
+ with PPD API deprecation warnings making more important
+ warnings being overlooked.
+ - cups-browsed: When removing a local queue on shutdown or
+ when DNS-SD reports the printer as disappeared check whether
+ the local queue got overwritten by an external process as
+ sometimes the shutdown or disappearing event comes too close
+ for cups-browsed receiving a printer-modified notification
+ from CUPS before (Ubuntu bug #1731417).
+
+CHANGES IN V1.22.5
+
+ - foomatic-rip: Changed Ghostscript call to count pages in a
+ PDF file to use "runpdfbegin" and not the undocumented
+ Ghostscript internal "pdfdict", so that it works with
+ Ghostscript 9.27 and later (Debian bug #926576, Arch Linux
+ bug #62251).
+
+CHANGES IN V1.22.4
+
+ - cups-browsed: Fix broken trailing space removal on
+ "NickName" (Pull request #103).
+ - pdftops: Emit PostScript Level 2 instead of Level 3 for
+ Brother PostScript printers as at least some of them
+ report to support level 3 but ontly work with Level 2
+ (Ubuntu bug #1306849, comment #42).
+ - bannertopdf: When multiplying the page for N-up or Duplex
+ printing one page too much was generated (Issue #102).
+
+CHANGES IN V1.22.3
+
+ - libcupsfilters: Added error checks for processing GIF, to
+ avoid crashes or hangs on broken GIF files (Issues #81, #82,
+ Pull request #100).
+ - cups-browsed: Added hint to the man page and configuration
+ file that with "DebugLogging stderr" the logging output goes
+ to journal or syslog if cups-browsed is running as system
+ service (Issue #28).
+
+CHANGES IN V1.22.2
+
+ - cups-browsed: Let distribution of jobs sent to queues with
+ "implicitclass" backend (usually clusters) be done by a
+ "job-state" CUPS notification and not by
+ "printer-state-changed" any more. The "job-state"
+ notification already contains the job ID. Before we had to
+ poll the job ID from CUPS via IPP which was sometimes
+ unreliable (Issue #97).
+ - imagetopdf, imagetoraster, pdftopdf, libcupsfilters: Added
+ new page scaling options: "fill" scales the input page
+ (typically a photo) so that the output page (typically with
+ different aspect ratio) gets completely filled, aloowing for
+ some content of the input page getting lost. "crop-to-fit"
+ allows for easy printing of documents on slightly different
+ output page sizes (A4 <-> Letter) maintaining the size and
+ centering and cropping into the destination page. Thanks to
+ Dheeraj Yadav (dhirajyadav135 at gmail dot com) for the
+ patch (Pull request #92).
+ - cups-browsed: Do not do IPP request for printer-is-shared
+ option for remote cups queues with CUPS 2.2.x and newer
+ (Pull request #91).
+ - cups-browsed: Fix crash bug when reading "Cluster"
+ directive from configuration file (Issue #94).
+ - driverless: Updated man page as now also Mopria and
+ Wi-Fi Direct printers are supported. Mentioned also
+ ippusbxd.
+
+CHANGES IN V1.22.1
+
+ - braille: Use sort command with LC_ALL=C for reproducibility
+ of the genrated files, needed for distribution packaging.
+ - cups-browsed, driverless: When polling the printer's
+ capabilities via get-printer-attributes IPP request for
+ driverless printing, use the attributes "all" and
+ "media-col-database". Without "all" some printers do not
+ report "urf-supported" and without "media-col-database" not
+ all paper size and marging info gets reported (Issue #22,
+ Pull request #86, CUPS issue #5484).
+ - braille: Document how to rework output before
+ embossing. Thanks to Samuel Thibault for this patch (Pull
+ request #90).
+
+CHANGES IN V1.22.0
+
+ - pdftopdf: Use QPDF for flattening interactive PDF forms
+ (Issues #2, #23, #36, Pull request #88).
+ - pdftopdf: Fixed bug of closing temporary file prematurely
+ when external PDF form flattening utilities fail (Thanks to
+ Tobias Hoffmann for finding this, see pull request #88).
+ - pdftoopvp: More fixes for building with Poppler 0.72
+ (Pull request #83, Issue #75).
+ - pdftoraster, pdftoijs, pdftoopvp: Removed support for
+ Poppler 0.18 (Pull request #83).
+ - cups-browsed: Fixed crash in applying the BrowseFilter
+ cups-browsed.conf directives (Debian bug #916765).
+
+CHANGES IN V1.21.6
+
+ - cups-browsed: To find out whether a DNS-SD-discovered
+ printer is from the local machine, use not only the flags in
+ the Avahi lookup result but also check the host name.
+ - cups-browsed: When a local CUPS queue pointing to a remote
+ CUPS printer was removed and re-created to make it a
+ permanent queue, on_printer_deleted() was triggered by
+ cupsd's notification to re-create a lost queue. Now
+ on_printer_deleted() checks whether the queue is really gone
+ and only re-creates then (Issue #80).
+ - cups-browsed: When updating the CUPS queues, also removed
+ and unregistered queues and not only created queues got
+ checked for HTTP timeouts, which caused crashes on shutdown
+ (Issue #79, Debian bug #916149).
+ - pdftops: Use the PS interpreter of Poppler for all Apple
+ LaserWriter 16/600, 4/600, 12/640, 12/600, 12/660 as they
+ all seem to not work with Ghostscript's PS output (Issue
+ #76).
+ - cups-browsed: On shutdown queues got removed even if they
+ still had jobs (Debian bug #908147).
+
+CHANGES IN V1.21.5
+
+ - cups-browsed: We cannot reliably determine whether a CUPS
+ queue is temporary, so we apply the procedure to make a
+ temporary queue permanent to any unshared queue (Debian bugs
+ #910882, #905850, #908604).
+ - pdftoraster, pdftopdf, pdftoijs, pdftoopvp: Do not use the
+ Poppler-specific "GBool", "gFalse", "gTrue" any more, as
+ Poppler has switched to standard "bool", "false", "true" in
+ version 0.71.0 (Issue #69).
+
+CHANGES IN V1.21.4
+
+ - cups-browsed: Limit the number of retries for
+ creating a print queue when it comes to HTTP
+ timeouts. Number of retries given by HttpMaxRetries
+ directive in cups-browsed.conf. Thanks to Zdenek Dohnal for
+ the patch (Pull request #73, Red Hat bug #1648697).
+ - cups-browsed: Read out current time right before setting the
+ timeouts. Thanks to Zdenek Dohnal for the patch (Pull
+ request #71, Red Hat bug #1648697).
+ - libcupsfilters: In the PPD generator for driverless IPP
+ printing let "*cupsManualCopies: true" lines get added to
+ the PPD if printing is done in a raster format as then
+ pdftopdf needs to generate the copies.
+ - pdftoraster, pdftoopvp, pdftoijs: Fix build with Poppler >=
+ 0.70 (Issue #69, Pull request #70).
+ - pdftopdf: Fixed printing multiple copies on driverless IPP
+ printers. When printing collated copies the multiple copies
+ got applied twice, resulting in n*n instead of n copies
+ (CUPS issue #5433).
+ - pdftoraster, pdftoopvp, pdftoijs: Poppler removed memCheck
+ and gMemReport functions, remove appropriate calls (Issue
+ #62, Pull request #66).
+
+CHANGES IN V1.21.3
+
+ - foomatic-rip: Reset stdin after replacing the underlying file
+ descriptor (Issue #58).
+
+CHANGES IN V1.21.2
+
+ - cups-browsed: Fixed freeing of literal string caused by
+ Coverity Scan issue fix (Debian bug #907399).
+
+CHANGES IN V1.21.1
+
+ - foomatic-rip: Fixed segmentation fault caused by wrong
+ Coverity Scan issue fix (Issue #57, Debian bug #907026).
+ - Build system: Require QPDF 8.1.0 or later as it is needed by
+ bannertopdf (Issue #56).
+
+CHANGES IN V1.21.0
+
+ - libcupsfilters, cups-browsed, driverless, foomatic-rip,
+ parallel: Silenced warnings from newest gcc.
+ - libcupsfilters: When generating a PPD for driverless
+ printing on a remote IPP printer, make pdftopdf not being
+ run by the local queue if the remote queue is a CUPS queue
+ to avoid running pdftopdf twice (CUPS Issue #5361).
+ - libcupsfilters, cups-browsed, driverless, bannertopdf,
+ foomatic-rip, pdftops, pdftoraster, rastertops,
+ rastertoescpx, sys5ippprinter, beh: Fixed Coverity Scan
+ issues. Thanks to Zdenek Dohnal (zdohnal at redhat dot com)
+ for the tests and the patches.
+ - bannertopdf: Switched over from using Poppler to using QPDF
+ for generating the PDF pages. With Poppler unstable APIs
+ were used which were subject to change. Thanks to Sahil
+ Arora for this project in the Google Summer of Code 2018
+ (Pull request #25).
+ - cups-browsed: Manually defined clusters ("Cluster" directive
+ in cups-browsed.conf) caused cups-browsed to crash.
+
+CHANGES IN V1.20.4
+
+ - README: Added link to Issue Tracker on GitHub.
+ - gstoraster: Removed unneeded "if"s. Thanks to Laurent
+ Martelli (martellilaurent at gmail dot com) for the patch
+ (Ghostscript bug #692705).
+ - cups-browsed: When checking whether there is already a local
+ print queue with the same URI as the one of the discovered
+ printer, consider also as equal URI if the URIs only differ
+ by use of IPP or IPPS and/or use of HTTPS port 443 instead
+ of IPP port 631.
+ - cups-browsed: Also upgrade from ipp: to ipps: when the ipps:
+ URI is on HTTPS port 443 instead of IPP port 631. This is
+ common on IPP network printers.
+ - pdftopdf: Removed support for hardware-implemented reversing
+ of page order in PostScript printers. It was once not
+ correctly implemented in cups-filters and second, such
+ printers are extremely rare, and on Gutenprint PPDs with
+ pseudo OutputOrder option hardware reversing was even
+ wrongly assumed (Issue #47).
+ - pdftopdf: Accept option "output-order=normal/reverse" for
+ reversing page order (Issue #47) and also "page-delivery=
+ same-order/reverse-order" (CUPS Issue #5340).
+ - libcupsfilters: Let the PPD generator add "*PageStackOrder
+ ..." lines to the choices of the "OutputBin" option, to
+ mark which output bins need the pages printed in reverse
+ order (Issue #47).
+ - libcupsfilters: Let the PPD generator correctly create a
+ "*DefaultOutputOrder: ..." entry, depending on whether the
+ paper is put out face-up or face-down in the default output
+ bin (Issue #47).
+ - libcupsfilters: Fixed human-readable name of the OutputBin
+ option in the PPD generator.
+ - pdftoopvp: Silence compiler warning (Issue #42).
+ - cups-browsed: If the user modifies/overwrites a print queue
+ created by cups-browsed, it will now not only be
+ automatically released from the control of cups-browsed, but
+ we also create a replacement for our generated local queue
+ under a new name.
+ - cups-browsed: Make URIS for using the implicitclass backend
+ correctly working also with queue names containing an '@'
+ character.
+ - braille: Strengthen error checking (Pull request #41).
+ - braille: Index: Replace bogus characters with space (Pull
+ request #41).
+ - braille: Add print and braille page number options (Pull
+ request #41).
+ - braille: Index: Use standard duplex cups option (Pull
+ request #41).
+ - cups-browsed: Moved auto-generation of PPD file for IPP
+ network printers from create_remote_printer_entry()
+ function to update_cups_queues(). This allows re-creating
+ accidentally removed or overwritten local queues without
+ losing the PPD file.
+ - braille: Add option to pick hyphenation rule according to
+ current locale and make it the default for second
+ translation table. Thanks to Samuel Thibault for this patch
+ (Pull request #38 and #39).
+ - braille: Remove generated defs on "make clean". Thanks to
+ Samuel Thibault for this patch (Pull request #38).
+ - braille: Turn non-breakable spaces to spaces. Thanks to
+ Samuel Thibault for this patch (Pull request #38 and #39).
+ - braille: Fix character encoding when extracting text. When
+ extracing text from a zip file or a pdf, the resulting text
+ is always utf-8 independently of the original locale, so we
+ need to force that. Thanks to Samuel Thibault for this patch
+ (Pull request #38).
+ - braille: Warn when no text translation was selected in case
+ the user didn't notice. Thanks to Samuel Thibault for this
+ patch (Pull request #37).
+ - braille: Fix spurious spacing after last Form-Feed (Pull
+ request #45).
+
+CHANGES IN V1.20.3
+
+ - braille: Do not remove read permission on cups-brf. Thanks
+ to Samuel Thibault for this patch (Pull request #32).
+ - braille: Get braille table descriptions from liblouis
+ metadata. Thanks to Samuel Thibault for this patch (Pull
+ request #31).
+ - braille: Select liblouis tables based on metadata before
+ using file names. Thanks to Samuel Thibault for this patch
+ (Pull request #30).
+ - cups-browsed: The new method of identifying remote CUPS
+ queues via the "printer-type" TXT record field does not work
+ for printers discovered by legacy CUPS broadcast (CUPS 1.5.x
+ or older). Now consider also printers without TXT record
+ (not discovered via DNS-SD) as remote CUPS queues (Issue
+ #34).
+ - gstoraster: Improved detection whether input is PostScript
+ or PDF by skipping over possible headers. Thanks to Rod
+ Schmidt (schmidtrod at q dot com) for the patch.
+
+CHANGES IN V1.20.2
+
+ - cups-browsed: If the user modifies/overwrites a print queue
+ created by cups-browsed, it will now automatically released
+ from the control of cups-browsed, so the modified queue does
+ not get removed by cups-browsed on shutdown. (Ubuntu bug
+ #1731417).
+ - cups-browsed: The configuration setting
+ "CreateIPPPrinterQueues LocalOnly" suppressed also the
+ automatic generation of local queues for remote CUPS
+ printers whereas this option is only intended for physical
+ IPP printers.
+ - cups-browsed: Identify remote CUPS queues by the
+ "printer-type" TXT record entry and not by the
+ "ipp(s)://<host>/printers/<name>" URIs, there are also IPP
+ network printers with such URIs (HP LaserJet Professional
+ M1212nf MFP in Ubuntu bug #1731417).
+ - .gitignore: Added filter/braille/filters/brftopagedbrf
+ - cups-browsed, foomatic-rip: Fixed several typos. Thanks to
+ Didier Raboud for the patches.
+
+CHANGES IN V1.20.1
+
+ - libcupsfilters: Silenced warning when using CUPS < 2.x by
+ eliminating the use of a recently introduced CUPS library
+ function (Bugzilla bug #1421).
+ - braille: Fix some missing options on indexv4. Thanks to
+ Samuel Thibault for this patch (Pull request #21).
+ - braille: Fix disabling margins on indexv4 in graphic
+ mode. Thanks to Samuel Thibault for this patch (Pull request
+ #20).
+ - braille: Fix installation of brftopagedbrf. Thanks to Samuel
+ Thibault for this patch (Pull request #18, Issue #17).
+ - cups-browsed: Fixed crash when CUPS reports a print queue
+ without "device-uri" attribute when cups-browsed polls a
+ list of local CUPS queues (Issue #16).
+
+CHANGES IN V1.20.0
+
+ - libcupsfilters: Let the PPD generator prefer the English
+ translation file from CUPS for the human-readable strings in
+ the PPD files.
+ - libcupsfilters: The PPD generator lists all page sizes with
+ human-readable names now, including proprietary names of the
+ printer.
+ - cups-browsed, driverless: Fixed get-printer-attributes call
+ on driverless printers for generating the PPD, explicitly
+ requesting the media-col-database attribute as otherwise
+ borderless page sizes do not appear.
+ - libcupsfilters: Fixed loading option/choice strings lists
+ from driverless printers for PPD file generation. Especially
+ proprietary media types appear correctly now.
+ - libcupsfilters: Completed color space support in the PPD
+ generator: Added DeviceGray/RGB/CMYK, default to 8 bit for
+ SRGB and to 16 bit for AdobeRGB, avoid duplicate listings of
+ the same color space.
+
+CHANGES IN V1.19.0
+
+ - libcupsfilters: Let the PPD generator add the options "Print
+ Optimization", "Print Rendering Intent" and "Print Scaling"
+ if appropriate IPP attributes are found.
+ - libcupsfilters: Let the PPD generator read out the maximum
+ of info about color spaces and this way not only reliably
+ the correct choices are added to the ColorModel option but
+ also the maximum supported bit depth (8 or 16 bit) is used.
+ - libcupsfilters: Overtaken new features from CUPS' PPD
+ generator: Presets, Finishing Templates, and extraction of
+ media sizes from "media-col-database"
+ - libcupsfilters: Improvements on header of generated PPDs:
+ use cups-filters version number, "drvless.ppd" PCFileName,
+ APSupplies and cupsChargeInfoURI from CUPS.
+ - libcupsfilters: Let the PPD generator use the IPP string
+ tables in the translation files of CUPS 2.3.x or newer
+ (English strings only). Let all options in the PPD have
+ human-readable option and choice names. In case of CUPS
+ 2.2.x or older (or if the CUPS translation are missing) we
+ fall back to internal tables.
+ - cups-browsed: Improved debug output when checking IPP
+ attributes of IPP printers.
+ - .gitignore: Ignore also core files.
+ - cups-browsed: Support use of PPD files generated by CUPS for
+ IPP Printers. Works only if the the local queue created by
+ cups-browsed replaces a temporary queue from CUPS.
+ Configurable via "UseCUPSGeneratedPPDs" directive in
+ cups-browsed.conf.
+
+CHANGES IN V1.18.0
+
+ - braille: Add support for page-ranges option. Thanks to
+ Samuel Thibault for this patch (Pull request #12).
+ - braille: Fix supporting docx and LO file names with
+ spaces. Thanks to Samuel Thibault for this patch (Pull
+ request #11).
+ - .gitignore: Updated and cleaned up.
+ - Build system: Make sure that "make dist" always includes all
+ files of the repository, plus the files generated by
+ ./autogen.sh, independent of the system configuration and
+ the used ./configure options.
+ - pdftoijs, pdftoopvp: Build pdftoijs and pdftoopvp only on
+ demand (via "--enable-ijs" and "--enable-opvp" on the
+ ./configure command line). There are actually no known
+ printer drivers using these filters. If no one complains
+ about the missing filters they will get completely removed.
+ - Build system: Set default path for pdftops to
+ /usr/bin/pdftops also for cross-compiling (Bug #1417).
+ - cups-browsed: Set "printer-location" as an attribute and not
+ as an option when creating/updating a CUPS queue (Bug
+ #1413).
+ - braille: Fix handling non-printable characters in BRF
+ files. Thanks to Samuel Thibault for this patch.
+ - braille: Fix printing backslashes in BRF files. Thanks to
+ Samuel Thibault for this patch.
+ - braille: use application/vnd.cups-brf instead of
+ text/vnd.cups-brf. Thanks to Samuel Thibault for this patch.
+ - braille: Make sure liblouis emits pure BRF output. Thanks to
+ Samuel Thibault for this patch.
+ - braille: Spaces at the head of lines were not getting
+ embossed, because bash would eat them in the read
+ command. IFS allows to avoid the issue. Thanks to Samuel
+ Thibault for this patch.
+ - gstoraster: Emit proper error message if Ghostscript is
+ missing. Thanks to Peter De Wachter (pdewacht at gmail dot
+ com) for the patch (Bug #1415).
+ - braille: Old bash does not like quotes, like in '$(("123" +
+ 0))'. Removed unneeded quotes. Thanks to Samuel Thibault for
+ this patch.
+ - braille: Index V5 embossers are compatible with the V4
+ protocol so we do not need driver changes, we just need to
+ advertise the support. Thanks to Samuel Thibault for this
+ patch.
+
+CHANGES IN V1.17.9
+
+ - cups-browsed: Applying option defaults from the
+ DefaultOptions directive in cups-browsed.conf got
+ lost. Re-introduced it (Bug #1414).
+ - cups-browsed: Get printer-location field from remote
+ printers. Thanks to Marek Kasik for the patch (Bug #1413).
+
+CHANGES IN V1.17.8
+
+ - foomatic-rip: Change execution of renderer thread to fail
+ whenever any of its individual sub-comands fails. Thanks to
+ LUUM (luum at chromium dot org) for the patch (Bug #1412).
+ - foomatic-rip: Parent process now ignores SIGPIPE calls from
+ upstream/downstream CUPS filters, per
+ https://www.cups.org/doc/api-filter.html, while correctly
+ noting child process failures and exiting
+ accordingly. Thanks to LUUM (luum at chromium dot org) for
+ the patch (Bug #1412).
+ - Build system: Fixed typo which broke the
+ "--enable-gs-ps2write" ./configure command line option (Bug
+ #1410).
+
+CHANGES IN V1.17.7
+
+ - braille: Add a mirror option for graphical output. Thanks to
+ Samuel Thibault for this patch.
+ - braille: Rename the internal cups name of the Resize option
+ to the standard well-known and well-documented fitplot
+ option. Thanks to Samuel Thibault for this patch.
+ - braille: Add support for margins in graphical mode,
+ defaulting them to 15 points (a bit more than 5mm). Thanks
+ to Samuel Thibault for this patch.
+ - braille: Updated French translation. Thanks to Samuel
+ Thibault for this patch.
+ - braille: Add a PPD which generates UBRL output, i.e. Braille
+ expressed in Unicode. This is not useful for actual
+ embossers, but very convenient to check output to be
+ embossed without wasting paper. Thanks to Samuel Thibault
+ for this patch.
+ - braille: Add virtual BRF backend for generating
+ ready-to-emboss BRF files with CUPS, similarly to the
+ cups-pdf backend. Thanks to Samuel Thibault for this patch.
+ - braille: Some tools seem to emit true/false instead of
+ True/False, so let us cope with it. Thanks to Samuel
+ Thibault for this patch.
+ - braille: "make uninstall" did not remove all the
+ links. Thanks to Samuel Thibault for this patch.
+ - braille: Add support for embossing MusicXML files, through
+ the FreeDots transcriptor. Thanks to Samuel Thibault for
+ this patch.
+ - braille: Add proper support for hardware margins on braille
+ embossers. Thanks to Samuel Thibault for this patch.
+ - braille: Fix the disabling of the text margins in Index
+ graphics mode. Thanks to Samuel Thibault for this patch.
+ - braille: Support for direct, structured embossing of XML and
+ XML-based file formats (like odt, docx, ...). Thanks to
+ Samuel Thibault for this patch.
+
+CHANGES IN V1.17.6
+
+ - braille: Embossers can only emboss integer numbers of 2x4
+ cells. Thanks to Samuel Thibault for this patch.
+ - braille: In Index graphical mode we need to disable the text
+ margins, since they come in earlier on the way to
+ there. Thanks to Samuel Thibault for this patch.
+ - braille: Also, we should always add a 1.6mm margin for
+ taking into account the width of dots. Thanks to Samuel
+ Thibault for this patch.
+
+CHANGES IN V1.17.5
+
+ - libcupsfilters: In the PPD generator for driverless printing
+ renamed the "print-quality" option back to
+ "cupsPrintQuality" as the support for this option got fixed
+ in CUPS (CUPS issue #5090).
+ - braille: Improvements on the braille support for bitmap
+ images: Moves the graphical dot distance option to the image
+ conversion group, add an option to avoid image resize, and
+ make the rotation option easier by proposing to just fit
+ paper instead of fitting portrait or landscape. Thanks to
+ Samuel Thibault for this patch.
+ - braille: Support for embossing vector images as braille.
+ Thanks to Samuel Thibault for this patch.
+ - braille: Fix liblouis1.defs installation. Thanks to Samuel
+ Thibault for this fix.
+
+CHANGES IN V1.17.4
+
+ - pdftopdf: If the input PDF file contains an interactive
+ form, flatten it to static PDF so that further manipulation,
+ like scaling, number-up, ... do not let the filled for
+ content getting lost. This is implemented by using the
+ pdftocairo utility of Poppler and if this fails Ghostscript
+ (9.22 or later recommended). This will probably replaced by
+ a QPDF-based solution later. Thanks to Tobias Hoffmann for
+ the QPDF-based detection of PDF forms (Bug #1315, Ubuntu bug
+ #1564249).
+
+CHANGES IN V1.17.3
+
+ - bannertopdf: Make it working also with Poppler 0.58.0 and
+ newer (Bug #1408).
+ - gstoraster, pdftops, foomatic-rip: Added "-dShowAcroForm" to
+ all Ghostscript command lines where the input data format
+ can be PDF. With this and the fix of Ghostscript bug
+ #698461 most filled PDF forms should be rendered correctly
+ by Ghostscript now.
+ - libcupsfilters: Do not check maximum resolutions of
+ raster-based PDLs, as implementation was incorrect and
+ reliability of PDLs is more important than maximum
+ resolution.
+
+CHANGES IN V1.17.2
+
+ - rastertopdf: Fixed outstanding bug in PCLm with JPEG (DCT)
+ compression. Now PCLm support is completely working.
+
+CHANGES IN V1.17.1
+
+ - libcupsfilters: Added direct PNG printing to the PPD
+ generator, the one of CUPS has it, too.
+ - libcupsfilters: In the PPD file generator renamed the option
+ "cupsPrintQuality" into the IPP name "print-quality" as CUPS
+ does not update the "print-quality=4" entry in the filter
+ command line based on the setting of "cupsPrintQuality"
+ (CUPS issue #5090).
+ - libcupsfilters: Completely redone the way how to determine
+ the resolutions to use for the default resolution and print
+ quality option in the PPDs generated for IPP
+ printers. Resolution lists from IPP attributes are now read
+ into sorted, duplicate-free lists with wrong resolutions
+ removed or fixed. Resolutions actually used are the common
+ ones between the supported PDLs, PDls with inferior maximum
+ resolution or with broken resolution list are skipped
+ (Debian bug #868360, Ubuntu bug #1712019, CUPS issue #5088,
+ CUPS issue #5091).
+ - rastertopdf: Prefer RLE compression instead of Flate as
+ there are HP printers where Flate is buggy.
+ - Build system: Fixed help mesage for "--enable-driverless"
+ configure option (Bug #1405).
+
+CHANGES IN V1.17.0
+
+ - rastertopdf, rastertopclm, driverless, cups-browsed,
+ libcupsfilters: Added support for the PCLm output format for
+ driverless printing on printers using Wi-Fi Direct and other
+ driverless printing standards.
+ printers. This is the Google Summer of Code 2017 project of
+ Sahil Arora (sahilarora dot 535 at gmail dot com). Thank you
+ very much for your great work! The PCLm support requires
+ QPDF 7.0.0 or later.
+
+CHANGES IN V1.16.4
+
+ - Build system: Switched over to C11 standard with GNU
+ extensions (-std=gnu11).
+ - Build system: Removed -pedantic flag as it is only needed
+ for compatibility with commercial compilers like the ones of
+ Windows (and we use GNU extensions anyway).
+ - libfontembed, texttopdf: reverted removal of anonymous
+ union.
+
+CHANGES IN V1.16.3
+
+ - libfontembed: Reverted unneeded soname change.
+
+CHANGES IN V1.16.2
+
+ - README: Minimum CUPS requirement of cups-filters is CUPS
+ 1.4.x. It does not build with earlier CUPS versions (Bug
+ #993).
+ - driverless, foomatic-rip: Create relative symbolic links.
+ - All C/C++ files: Silenced all compiler warnings, at least
+ the ones appearing when building on Ubuntu Linux 17.10 with
+ GCC 7.1.0.
+ - README: Updated the introduction section to reflect the
+ current functionality of cups-filters, and the build
+ requirements for the Poppler-based filters (C++11: Bug
+ #1404, Build configuration of Poppler: Bug #1257). Thanks to
+ Roland Hieber (r dot hieber at pengutronix dot de) to find
+ out about this.
+ - pdftoopvp, bannertopdf, pdftoraster: Build with C++11
+ standard as some features of this standard are needed by
+ these filters (or by Poppler). Thanks to Roland Hieber (r
+ dot hieber at pengutronix dot de) for the patch (Bug #1404).
+
+CHANGES IN V1.16.1
+
+ - cups-browsed: Make timeouts for HTTP access to the local
+ CUPS daemon and remote IPP printers configurable. Thanks to
+ Cedric Dufour (cedric dot dufour at idiap dot ch) for the
+ patch (Bug #1387, Debian bug #852436).
+ - texttopdf: Allow bold and underline formatting to be used
+ together when using "prettyprint". Thanks to Michael Moran
+ (vampm at comcast dot net) for the patch.
+ - texttopdf: Allow to alter margins, and chars/lines per Inch
+ when using "prettyprint". Thanks to Michael Moran (vampm at
+ comcast dot net) for the patch.
+ - texttopdf: When "prettyprint" is used, do not drop out of
+ C/shell comment mode too early. Thanks to Michael Moran
+ (vampm at comcast dot net) for the patch.
+ - cups-browsed: Additional NULL checks for description and
+ location.
+ - cups-browsed: Fixed crash which happens when using
+ BrowsePoll (Debian bug #723835).
+
+CHANGES IN V1.16.0
+
+ - cups-browsed: Let elements in arrays get stacked up in the
+ order they are added, before, they were in the order how
+ they are positioned in memory. This especially led to a
+ random order of printer cluster definitions and of
+ command-line-supplied configuration options.
+ - cups-browsed: On shutdown not all locally created queues got
+ deleted.
+ - cups-browsed: Added support for manual definition of
+ load-balancing printer clusters via the "Cluster" directive
+ in cups-browsed.conf.
+
+CHANGES IN V1.15.0
+
+ - cups-browsed: Removed the function to compare printer entries
+ for sorting the printer entry list. This led to corruption
+ of the list and so to crashes.
+ - cups-browsed: Fixed crashes when many printers (especially
+ all printers of a load-balanced cluster) are removed at once.
+ - cups-browsed: Log the full list of handled remote printers
+ whenever one is added or removed.
+ - cups-browsed: Renamed the handle_cups_queues() function to
+ update_cups_queues() to better reflect what it is doing.
+ - cups-browsed: When clustering remote CUPS printers together
+ do not call them duplicates but slaves asigned to a master.
+ - cups-browsed: Log the error if the network interface name of
+ a DNS-SD event could not be determined.
+ - cups-browsed: Simplified printer entry removal procedure.
+ - cups-browsed: Log memeber printer list of a printer cluster
+ (implicit class) when a member printer is added or removed.
+ - cups-browsed: Removed superfluous (and not correctly
+ working) duplicate counter from the remote printer entry
+ data structure.
+ - cups-browsed: Add "AutoClustering" directive to
+ cups-browsed.conf to turn on and off automatically
+ clustering equally named local print queues which point to
+ remote CUPS printers. When automatic clustering is turned
+ off, queue name clashes are prevented by adding "@<server
+ name>" to local queue names based on the remote queue name
+ or on make and model.
+ - cups-browsed: Skip callback functions and the CUPS queue
+ creation/update/removal loop when cups-browsed is terminated
+ by a SIGTERM signal. This avoids hanging on shutdown. Thanks
+ to Edgar Fuss (ef at math dot uni-bonn dot de, Bug #1402).
+ - libcupsfilters: Added some fallbacks for incorrect
+ resolution IPP attributes on IPP network printers (Debian
+ bug #868360).
+ - pdftoopvp: Added missing "#include <math.h>" needed for
+ cross-compiling for arm-v7a-linux-gnueabi (Bug #1232).
+ - cups-browsed: Prevent the creation of two remote printer
+ entries for two IPP network printers or an IPP network
+ printer and a remote CUPS printer with the same local queue
+ name. This could easily happen with make/model-based naming.
+ - cups-browsed: Added the possibility to optionally not
+ create local queues for remote printers for which CUPS
+ (from 2.2.x on) auto-creates queues by itself (DNS-SD
+ advertised driverless printers).
+ - cups-browsed: Removed repeated code for clean-up when
+ generate_local_queue() function fails.
+ - cups-browsed: Take care of CUPS' temporary queues. Do not
+ consider them when checking whether a queue with the same
+ name as the one we are creating already exists and make
+ temporary queues permanent (or remove them) before
+ overwriting them with our local queue.
+ - cups-browsed: Make the naming scheme for locally created
+ print queue configurable, especially allow for naming based
+ on the DNS-SD service name (now default) as this is the same
+ scheme as CUPS uses for its temporary queues. This way we
+ prevent CUPS creating temporary queues when cups-browsed is
+ already creating a queue.
+ - cups-browsed: Do not add "APRemoteQueueID" keyword to the
+ local queue's PPD file if the queue is for an IPP network
+ printer.
+ - cups-browsed: Skip multiple browse entries for the same
+ printer with interface alias addresses. Thanks to Edgar
+ Fuss (ef at math dot uni-bonn dot de, Bug #1399).
+ - cups-browsed: Improved support for Description (Info) and
+ Location fields of remote CUPS queues. Thanks to Edgar Fuss
+ (ef at math dot uni-bonn dot de, Bug #1398).
+ - cups-browsed: Renamed variable names for better code
+ readability. Thanks to Edgar Fuss (ef at math dot uni-bonn
+ dot de, Bug #1398).
+ - cups-browsed: Additional NULL checks in the
+ create_local_queue() function. Thanks to Edgar Fuss (ef at
+ math dot uni-bonn dot de, Bug #1398).
+
+CHANGES IN V1.14.1
+
+ - cups-browsed: Do correct removal of printer entry handling
+ duplicates correctly also when a legacy CUPS-broadcasted
+ printer disappears or a printer remaining from the last
+ session does not appear again.
+ - cups-browsed: Use getline() instead of fgets() to read saved
+ option settings. This is less crash-prone (Ubuntu bug
+ #1658833).
+ - cups-browsed: Improved error logging when saving option
+ settings.
+ - cups-browsed: Added NULL checks for generate_local_queue()
+ and create_local_queue() functions.
+ - cups-browsed: When accessing local CUPS queues use always
+ the correct port of the CUPS daemon we are attached to.
+ - cups-browsed: Check whether a connection to the local CUPS
+ daemon actually happened before using it (Ubuntu bug
+ #1644049).
+ - cups-browsed: Set unused fields of printer record to NULL
+ when tranfering data from the record of a duplicate printer
+ to the record of a disappeared one.
+ - cups-browsed: Simplify removal of all queues on shutdown or
+ stop of Avahi.
+ - cups-browsed: When creating a record for a discovered
+ printer set it all zero before filling it in, to assure
+ that no field is in an undefined state.
+ - cups-browsed: All functions which are called via Glib
+ functions or otherwise event-triggered log now in which
+ thread they are running. This way one can see whether
+ problems can be caused by concurrent access to global
+ resources.
+ - cups-browsed: Do not check whether the DNS-SD event is from
+ the local machine in the browse_callback() function. We
+ cannot check the port here.
+ - cups-browsed: Added more NULL checks to Avahi callback
+ functions.
+ - cups-browsed: Added NULL check to avoid crashes in the Avahi
+ resolver callback (Ubuntu bug #1696967).
+ - libcupsfilters: Let PPD generator do case-insensitive
+ comparisons for PWG Raster color spaces, as some printers
+ (Epson) do not use the standard-conforming all-lowercase
+ form for them (CUPS Issue #4998).
+
+CHANGES IN V1.14.0
+
+ - cups-browsed: When a printer is discovered via DNS-SD on the
+ "lo" (loopback) interface the printer is not reliably
+ accessible through the reported host name (which is the
+ network host name of the local machine). Until this problem
+ is fixed in Avahi, we create queues for such printers with a
+ URI based on the IP address. This is a workaround until
+ Avahi fully supports the "lo" interface.
+ - cups-browsed: Added new setting "LocalOnly" for the
+ CreateIPPPrinterQueues in cups-browsed.conf. With this new
+ setting (which is the default from now on) only for local
+ printers made available as IPP printers (like IPP-over-USB
+ printers with ippusbxd) queues are auto-created. With this
+ we can follow the common standard of distributions where USB
+ printers are automatically set up and network printers not.
+ - cups-browsed: Fixes and improvements in comments and debug
+ messages: 1. Bonjour -> DNS-SD; 2. When a remote CUPS class
+ is discovered, tell that it is a class; 3. Show network
+ interface and IPv4/IPv6 when a DNS-Sd service appears or
+ disappears.
+ - cups-browsed: Added ./configure script option
+ "--enable-auto-setup-driverless" to let cups-browsed
+ automatically set up IPP network printers by default.
+
+CHANGES IN V1.13.5

+ - foomatic-rip: When called via the utility cupsfilter from
+ CUPS, foomatic-rip was not able to read the PPD file with
+ the file name supplied as environment variable PPD (Bug
+ #1388).
+ - driverless: Improved error message output.
+ - libcupsfilters: Fixed error handling of the PPD file
+ generator for driverless printing, so that callers get
+ decent error messages.
+ - libcupsfilters: Do not generate a PPD file where the only
+ output data format is JPEG, as JPEG does not support
+ multi-page documents.
+ - libcupsfilters: Let PPD generator skip broken page size
+ records and add warnings for debugging to the PPD.
+ - libcupsfilters: Updated PPD generator to match with the
+ current GIT state of the one of CUPS.
+ - braille: Automatically select a table according to the
+ current locale.
+ - braille: Update for liblouis table list.
+ - braille: Added support for text margins.
+ - cups-browsed: When creating a local queue for a remote CUPS
+ printer, add the line '*APRemoteQueueID: ""' to the PPD file
+ so that CUPS sets the CUPS_PRINTER_REMOTE bit for the
+ printer type of the local queue (Bug #1386).
+
+CHANGES IN V1.13.4
+
+ - libcupsfilters: Let PPD generator for driverless printing
+ not error out when there is no urf-supported or
+ pwg-raster-document-resolution-supported IPP attribute,
+ simply accept the default resolution also from the
+ printer-resolution-default attribute or set a default value
+ of 300 dpi to get a working PPD file.
+ - cups-browsed: Do not use deprecated names for IPP status
+ constants
+ - cups-browsed: Corrected determination whether an IPP status
+ is an error, to avoid "Unable to create/modify CUPS queue
+ (Success)" and infinite repetition of a succeeded operation
+ (Debian bug #852436).
+
+CHANGES IN V1.13.3
+
+ - libcupsfilters: When auto-generating PPD files added support
+ for passing through JPEG input to printers which understand
+ JPEG. This is also done in CUPS-generated PPDs (Debian bug
+ #851499).
+ - libcupsfilters: Added the "output-bin" option support from
+ CUPS' PPD generator to our PPD generator (CUPS Issue #4938).
+ - cups-browsed: Make support for printers with IPv6 IP address
+ work. Both link-local and regular addresses work.
+
+CHANGES IN V1.13.2
+
+ - cupsfilters.drv: Corrected cupsFilter entry for the "Generic
+ IPP Everywhere Printer".
+ - driverless: Fixes on the man page (Debian bug #849075).
+ - driverless: Do not error-exit (non-zero status) when run by
+ CUPS as backend or PPD generator when no driverless printer
+ is found or Avahi not running. When run from thr command
+ line, exit status is the same as of ippfind.
+ - imagetoraster: Removed (incomplete) PWG Raster support. For
+ PWG Raster output we let the rastertopwg filter from CUPS do
+ the finalization (mainly adding white pixels at the borders
+ to get a full-page bitmap).
+ - imagetoraster: Fixed several bugs in the calculation of the
+ page geometry (Debian bug #849380).
+ - libcupsfilters: If the IPP-polled printer has the
+ "sides-supported" attribute, determine the need of a
+ "Duplex" option solely whether the attribute has a
+ "two-sided-long-edge" choice and ignore the "duplex"
+ parameter of the ppdCreateFromIPP() function call. This lets
+ the more precise information coming from the IPP query
+ always be preferred against information from the Bonjour
+ record.
+ - driverless: When listing printers let the device ID contain
+ "AppleRaster" (for Apple Raster printers) and "PWGRaster"
+ (for IPP Everywhere printers) in the "CMD" field.
+ - driverless: Added "-T 3" to the ippfind command line. This
+ makes ippfind search the Bonjour broadcasts for up to 3
+ seconds when searching for IPP printers, raising the
+ reliability in finding all of them (Debian bug #848712).
+
+CHANGES IN V1.13.1
+
+ - cups-browsed: Avoid erroring out when restarting after a
+ crash (with generated queues not deleted due to the crash)
+ and the configuration option
+ CreateRemoteCUPSPrinterQueues=No being set.
+ - cups-browsed: If CUPS is stopped while cups-browsed is
+ running and there are queue for IPP network printers (not
+ remote CUPS queues) on restart of CUPS the still existing
+ local CUPS queue is not correctly re-connected with
+ cups-browsed and therefore gets removed after a
+ timeout. This should be fixed after a clean-up of
+ re-connecting with remaining queues from a previous session
+ (Debian bug #848223).
+ - cups-browsed: Generated queues did not get removed on
+ shutdown (Debian bug #848167).
+ - libcupsfilters: Let PPD generator for driverless printing
+ suppress page sizes which the printer reports more than
+ once (CUPS Issue #4933).
+ - driverless, libcupsfilters: Make "driverless list" output
+ and output of driverless as CUPS backend in discovery mode
+ add the word "driverless" to its output, to make it easier
+ to set up driverless printers with printer setup tools.
+ Made the NickName of the generated PPDs also match with the
+ "driverless list" output.
+
+CHANGES IN V1.13.0
+
+ - cups-browsed: Use the httpGetAddr() only with CUPS 2.0.x or
+ newer, as older CUPS versions do not provide it (Bug #1381).
+ - cups-browsed: Minor corrections in the handling of the data
+ records of the discovered printers.
+ - rastertopdf, urftopdf: As with libcupsimage from CUPS 2.2.2
+ on rastertopdf also understands Apple Raster and much better
+ than urftopdf does, use rastertopdf for Apple Raster
+ (image/urf) input files then. Also allow for manually
+ choosing by the ./configure command line.
+ - driverless: Added a CUPS backend mode to the driverless
+ utility. Running as a CUPS backend in discovery mode it
+ lists the IPP URIs of the suitable printers in printer setup
+ tools and in "lpinfo -v", as conneting via IPP is required
+ for driverless printing.
+
+CHANGES IN V1.12.0
+
+ - cups-browsed: Added new "CreateRemoteCUPSPrinterQueues"
+ directive to cups-browsed.conf, which allows to decide
+ whether to auto-create local print queues for shared CUPS
+ queues on remote machines. This way one can also set up
+ servers which only create queues for IPP network printers.
+ - driverless: Added new /usr/lib/cups/driver/driverless
+ utility to make CUPS auto-generate PPD files for printers
+ designed for driverless use (IPP Everywhere, Apple Raster)
+ when they are set up with a printer setup tool. This gives
+ transparency to set up these printers with legacy printer
+ setup tools. This utility is also linked to /ustr/bin to
+ manually generate PPDs via command line.
+ - libcupsfilters, cups-browsed: Moved the PPD generator for
+ IPP network printers from cups-browsed to libcupsfilters, so
+ that it can also be used by other utilities.
+ - cups-browsed: When auto-generating a PPD set the cost values
+ in the filter lines to give the highest priority to PDF,
+ then PWG Raster, Apple Raster, PCL-XL, PostScript, PCL 5c/e.
+ - cups-browsed: Synced the PPD generator with the one of CUPS,
+ giving the best possible support for IPP Everywhere and
+ AirPrint printers. Especially support for more media types
+ and for finishing units got added. Also support for more
+ different ways to represent the printer capabilities via
+ IPP attributes got added.
+ - cups-browsed: Added support for auto setup of IPP printers
+ understanding the Apple Raster input data format (.urf, on
+ AirPrint printers), only if CUPS 2.2.2 is used, which can
+ generate this format via its rastertopwg filter.
+ - cups-browsed: Added new "NewIPPPrinterQueuesShared"
+ directive to cups-browsed.conf, which allows to decide
+ whether the auto-created local print queue for a newly
+ discovered IPP network printer will be shared or not. For
+ printers discovered earlier, cups-browsed remembers the
+ previous setting.
+ - cups-browsed: If a user changes the printer-is-shared bit of
+ an auto-created print queue for an IPP network printer (not
+ for a remote CUPS queue), record this fact and recover the
+ change when creating this queue in the next session.
+ - cups-browsed: For automatic creation of print queues for IPP
+ network printers also allow only creating queues for IPP
+ Everywhere printers, only for Apple Raster printers, or for
+ both printer types designed for driverless printing and not
+ only for all suitable printers, configurable via the
+ CreateIPPPrinterQueues directive in cups-browsed.conf.
+
+CHANGES IN V1.11.6
+
+ - pdftops: Do not default to simply "pdftops" when calling the
+ Poppler pdftops utility, as the $PATH of CUPS when running
+ filters/backends starts with /usr/lib/cups/filter/ and then
+ pdftops would call itself (Bug #1380).
+
+CHANGES IN V1.11.5
+
+ - cups-browsed: Fixed several typos in the documentation (Bug
+ #1378).
+ - gstoraster, mupdftoraster, pdftops, sys5ippprinter: Use
+ execvp() and execvpe() to call programs so that the $PATH
+ environment variable gets used to find the programs (Bug
+ #1378).
+ - build system: Several fixes, especially to make it work when
+ cross-compiling or using a build server (Bug #1378).
+ - cups-browsed: Silenced a warning.
+ - cups-browsed: For remote CUPS queues with a dot in their
+ name no local queue got created (Bug #1379).
+ - pdftopdf: Do the page logging also for IPP Everywhere
+ printers which use the PWG Raster data format as the
+ ...toraster filters being the last filter then do not log.
+ - gstoraster, pdftoraster: Let filters generate PWG Raster if
+ the environment variable FINAL_CONTENT_TYPE is set to
+ image/pwg-raster, make sure full-page bitmaps are generated
+ in PWG_raster mode, and added mime conversion rules for
+ direct PWG Raster output.
+ - cups-browsed: Corrected checking of the PDLs of an IPP network
+ printer. Now PCL 5c/e printers (not HP inkjets) should get
+ recognized correctly.
+ - texttopdf: Added missing NULL check to avoid a segfault when
+ texttopdf does not find a suitable (monospace TTF) font.
+ - foomatic-rip: Replace old manpage macro calls from
+ foomatic-filters 3.0.2-20050114.
+ - cups-browsed: Allow changing BrowseInterval and
+ BrowseTimeout via cups-browsed.conf, as it was formerly with
+ CUPS (Debian bug #794655).
+ - pdftopdf: Count the actual output pages also if the
+ number-up option is not used, to correctly find out whether
+ we have an even or odd number of pages, even if the
+ page-ranges option is used. This is needed to correctly
+ decide whether for duplex printing a blank page has to be
+ added (Bug #1377).
+
+CHANGES IN V1.11.4
+
+ - gstoraster: Allow Ghostscript to use the center-of-pixel
+ method instead of the PostScript-standard any-part-of-pixel
+ method when rendering filled paths. This improves the
+ graphics output quality of low-resolution printers like
+ label printers, for example to assure readability of bar
+ codes (Bug #1373).
+ - cups-browsed: Fixes to avoid unneeded calls of
+ handle_cups_queues() and even infinite loops (Possible fix
+ for bug #1376). Also make sure that queues left over from
+ the previous cups-browsed session are integrated correctly.
+
+CHANGES IN V1.11.3
+
+ - cups-browsed: If a queue is not only discovered via Bonjour
+ but also via legacy CUPS or LDAP, prefer the Bonjour record
+ as it provides more information and there is also a defined
+ cancellation broadcast.
+ - cups-browsed: Let PPD options saved in the last session also
+ get applied to generated PPDs for IPP network printers.
+ - cups-browsed: Make sure that saved PPD options do not get
+ lost if for some reason the PPD file cannot be loaded in a
+ new cups-browsed session (or the loaded PPD file is
+ different). This is done by holding a copy of the settings
+ in the remote printer data structure.
+ - cups-browsed: When saving option settings, remove
+ backslashes added when the settings are read out via IPP
+ request. Otherwise the backslashes would double with each
+ session of cups-browsed.
+ - implicitclass: Do not let the job get immediately retried on
+ failure to send it out to the remote CUPS printer. By
+ repeating to send the job to an unavailable server so
+ quickly, cups-browsed gets bombed with requests and hangs on
+ shutdown.
+ - cups-browsed: Shortened timeouts of HTTP connections and IPP
+ requests to 3 seconds amd of IPP requests to remote CUPS
+ servers to 2 seconds. For local IPP requests always use the
+ connection once created via http_connect_local(). Also call
+ g_main_context_wakeup(NULL) after each
+ g_main_loop_quit(gmainloop) call. These measures should
+ reduce long hangs of cups-browsed on shutdown when a CUPS
+ server got unavailable.
+ - cups-browsed: Do not mark remote printers discovered via
+ legacy CUPS broadcasts as disappeared right from the
+ beginning to implement the browse timeout. Instead manage
+ their expiring by introducing a flag which marks them as
+ CUPS legacy printers. Printers with disappeared status are
+ considered invalid in some situations, especially when
+ clusterin equally-named remote printers (Bug #1374).
+ - cups-browsed: When we have remote CUPS printers, we use the
+ implicitclass backend and a local copy of the remote PPD
+ file already if we have only a single remote printer with
+ this queue name. This simplifies the management of remote
+ CUPS printers and also we do not hassle with using a remote
+ PPD file. Now one can change PPD option defaults with
+ printer setup tools or the lpadmin command and they get
+ preserved in the next cups-browsed sessions.
+ - if we are using the implicitclass backend CUPS does not make
+ the server's PPD file available on the client any more. To
+ fix this, we download the PPD file when creating an
+ implictclass:... queue and apply it to the queue. This way
+ the options of the printer(s) are always available for
+ enumeration, especially in print dialogs (Bug #1372). We
+ modify the local copy setting any options saved from the
+ previous session and inhibiting local execution of filters
+ (as the driver for the remote printer is not necessarily
+ available locally).
+ - cups-browsed: Added flag to inhibit auto-backup of option
+ settings by the on_printer_modified() notification handler
+ during print queue setup and removal.
+ - cups-browsed: Let the printer_record() function always
+ return the master record for the printer name and not an
+ arbitrary duplicate.
+ - cups-browsed: Fixes in the functionality for saving option
+ settings: Make sure to not save the same option twice with
+ different values, do not save the "printer-is-shared" option
+ (errors out when re-applying option in the next session).
+ - cups-browsed: Treat discovered printers correctly also if
+ they use a non-standard port, even if several CUPS daemons
+ are running on the same server but on different ports. This
+ also improves the support of a sandboxed printing stack.
+ - cups-browsed: Close http connections opened for polling
+ properties of IPP network printers, to fix a possible memory
+ leak.
+ - cups-browsed: Cleaned up HTTP access to local and remote
+ CUPS servers and IPP printers, to assure that the local CUPS
+ daemon is always accessed the same (user-defined) way
+ (domain socket/localhost:port). This especially prevents
+ cups-browwsed hanging on shutdown (Debian bug #832637).
+ - cups-browsed: Fixed clustering equally-named queues of
+ different remote servers, to assure to have one master
+ referencing to all duplicates and not a daisy chain of
+ duplicate references.
+
+CHANGES IN V1.11.2
+
+ - cups-browsed: Allow turning off the use of CUPS' domain
+ socket via cups-browsed.conf.
+ - foomatic-rip: When run as regular CUPS filter use preferably
+ /etc/cups/foomatic-rip.conf (or whereever the CUPS
+ configuration files reside, according to the CUPS_SERVERROOT
+ environment variable) as configuration file. This way we can
+ more easily run the printing stack in a sandbox.
+ - foomatic-rip: When run as regular CUPS filter, read the PPD
+ through CUPS and get the print queue name by environment
+ variable.
+ - bannertopdf, foomatic-rip, gstoraster, mupdftoraster,
+ pdftoopvp, pdftoraster: Do not use build-time hard-coded
+ paths, but always the paths from the environment variables
+ which CUPS sets when calling its filters. This is needed to
+ run the printing stack in a sandbox.
+
+CHANGES IN V1.11.1
+
+ - mupdftoraster: Lowered the priority (raised the cost value)
+ in the cupsfilters-mupdf.convs file so that in a full
+ cups-filters installation MuPDF is not prioritized.
+
+CHANGES IN V1.11.0
+
+ - pdftops: Added support for MuPDF as PDF renderer. MuPDF can
+ be selected by the "pdftops-renderer=mupdf" option.
+ - rastertops: Removed unneeded page logging.
+ - rastertops: Fixed DSC comments, some were only preceded by
+ a single '%' instead of a double "%%".
+ - gstoraster, pdftops, foomatic-rip: Use -dNOMEDIAATTRS when
+ calling Ghostscript. This way Ghostscript does not try to
+ match media sizes with internal lists.
+ - Build system: Allow building cups-filters without Poppler
+ (--disable-poppler in ./configure command line) This skips
+ the build of pdftoraster, bannertopdf, pdftoijs, and
+ pdftoopvp and the installation of these filters and their
+ auxiliary files. With this cups-filters can be easily
+ installed on mobile/appliance systems with MuPDF as the only
+ PDF interpreter.
+ - mupdftoraster: Added filter to support MuPDF as PDF
+ interpreter. MuPDF is a lightweight PDF interpreter
+ especially interesting for mobile systems and
+ appliances. Thanks to Pranjal Bhor for contributing this as
+ part of his Google Summer of Code project.
+ - gstoraster: Fix setting of width and height of the page in
+ pixels when there is no Resolution option in the PPD.
+ - cups-browsed, implicitclass: Avoid the use of files for the
+ communication between cups-browsed and the load-balancing
+ backend implicitclass. Instead of in a file, cups-brwsed
+ stores the destination server name in an option (which CUPS
+ saves in printers.conf) which the implicitclass backend
+ reads via IPP. This not only makes it easier to run
+ cups-filters in a sandbox, but it is also better in terms of
+ system security.
+ - cups-browsed: Allow configuring where the files produced by
+ cups-browsed will get stored. This makes it easier to run
+ cups-filters in a sandbox.
+ - beh: Fixed printing multiple copies with beh (Ubuntu bug
+ #1605514).
+ - cups-browsed: Fixed several memory leaks, especially when
+ using IPP requests and DNS-SD TXT record look-ups. Thanks to
+ Ivo Straka for finding them with Valgrind and supplying
+ patches to fix them (Bug #1365, Bug #1368, Ubuntu bug
+ #1203276).
+ - libcupsfilters: Added missing "#include <cups/ppd.h>" to
+ make sure that the package builds on all systems (Bug
+ #1366).
+
+CHANGES IN V1.10.0
+
+ - texttotext: Added new filter for text-only printers written
+ in C, to use the CUPS library to access the print queue's
+ PPD file, with a lot of options to fit practically all
+ printer models amd paper sizes, support for CUPS' page
+ management options, and support for configuring the print
+ queue and controlling the options by the PPD file. The PPD
+ is now generated on-the-fly by cupsfilters.drv.
+ - textonly: Removed the old script-based filter and its PPD
+ for text-only printers.
+ - rastertops: Added new filter to turn PWG Raster into
+ PostScript, in preparation for MuPDF support. Thanks to
+ Pranjal Bhor for contributing this as part of his Google
+ Summer of Code project.
+ - gstoraster, gstopxl, gstopdf, pstopdf: Integrated
+ functionality of script-based filters pstopdf and gstopxl
+ into gstoraster filter as script-based filters cannot access
+ the print queue's PPD file with current CUPS due to change
+ of PPD file permissions. To make gstoraster always produce
+ the correct output format (CUPS/PWG Raster, PDF, PCL-XL) it
+ is called via new wrapper scripts (gstopdf, gstopxl) which
+ set an environment variable telling the format. The old
+ filter scripts got removed.
+ - imagetops, texttops: Do not use $0 in the wrapper scripts,
+ when CUPS calls filters, it passes the queue name as $0, not
+ path and name of the called filter.
+ - cups-browsed: When creating local queues for discovered IPP
+ network printers always create PPD files and if the
+ information supplied by the printer via IPP is insufficient
+ use information from the DNS-SD entry or default values
+ suitable for most printers. Use System V interface scripts
+ only on explicit request in cups-browsed.conf. This change
+ is to address the fact that System V interface script
+ support is removed from CUPS 2.2.x and later for security
+ reasons.
+ - pstopdf: Make the filter only get installed if Ghostscript is
+ present and also moved its conversion rules into the
+ cupsfilters-ghostscript.convs file.
+ - cups-browsed: Fixed crash when trying to get debugg logging
+ both to the terminal and into a file.
+ - libcupsfilters: Fixed crash of pdftoraster when the color
+ space is an RGB space (3 colors) with 1 bit color
+ depth. Here we need to add one bit to the pixels (to get 4
+ bits per pixel) to align the pixels with the bytes.
+ - cups-browsed: From cups-browsed.service removed the unneeded
+ "Wants=cups.service" as we have "Requires=cups.service"
+ (Debian bug #827455, #827457).
+ - foomatic-rip: Updated man page for removed page logging
+ facility.
+ - pdftops: Also added Dell to the list of manufacturers whose
+ printers need Poppler's PostScript to work around their
+ PostScript interpreter bugs (Debian bug #827040).
+
+CHANGES IN V1.9.0
+
+ - foomatic-rip: Removed page logging via insertion of PostScript code.
+ This works only with Ghostscript and PostScript input and even
+ then it can break things or simply not work. We do the page logging
+ for foomatic-rip in pdftopdf now, which is more universal and more
+ reliable.
+ - sys5ippprinter: Added page logging (to /var/log/cups/page_log)
+ functionality.
+ - pdftopdf: Added functionality for logging pages in the
+ /var/log/cups/page_log file. Logging can also be forced or
+ surpressed via command line (page-logging=on/off/auto) and
+ page logging is also done for filters which should do but
+ actually do not do: foomatic-rip, gstopxl, hpps (CUPS issue #4798,
+ Ubuntu bug #1585380).
+ - pdftopdf: Whitespace and indentation clean-up.
+ - README: Removed the documentation of the old Poppler-based pdftopdf
+ filter which is not included any more.
+ - cups-browsed: Do not schedule failed operations for later repetition
+ during shutdown.
+ - cups-browsed: Added support for debug logging into a file (usually
+ /var/log/cups/cups-browsed_log, to be activated via "-l" or
+ "--logfile" option or via "DebugLogging file" option in
+ cups-browsed.conf.
+ - cups-browesd: Consistent use of debug_printf() in the LDAP support.
+ - cups-browsed: Added "Requires=cups-service" to the
+ cups-browsed.service file, so that systemd keeps CUPS running while
+ shutting down cups-browsed on system shutdown (Ubuntu bug #1579905).
+ - README: Extended pdftopdf's documentation.
+ - README: Added documentation for the pdfAutorotate option in
+ pdftopdf.
+ - gstoraster: Treat status output of the waitpid() function properly,
+ to avoid gstoraster exiting with zero status when Ghostscript
+ exited with non-zero status or got terminated by a signal
+ (Bug #1354).
+ - README: Fixed typos. Thanks to Pranjal Bhor (bhor dot pranjal at
+ gmail dot com) for the patch.
+ - braille: Recognize application/vnd.cups-pdf-banner MIME type and
+ read standard input directly instead of using /dev/stdin.
+ - braille: Drop output of the "type" command when checking the
+ presence of helper utilities.
+ - braille: Do not send EOF twice to the braille embosser.
+ - cups-browsed/sys5ippprinter: Fixed documentation about the allowed
+ input formats for auto-created network printer queues using
+ sys5ippprinter, also improved NEWS entry about renaming of
+ sys5ippprinter (Debian bug #819665).
+
+CHANGES IN V1.8.3
+
+ - cups-browsed: When creating or modifying a local print queue
+ set the printer-is-shared bit to false in a separate IPP
+ request as this operation errors on queues directly pointing
+ to remote CUPS queues with the IPP backend. This way we can
+ ignore the error and assure that all other settings are
+ applied (Ubuntu bug #1560099).
+ - Fixed pkg-config support so that $PKG_CONFIG gets used and
+ cross compilation works (Bug #1347).
+ - gstoraster: Put conversion rules for this filter into a
+ separate file, so that they do not get installed when we
+ build without Ghostscript support (Bug #1346).
+ - Allow disabling dependencies on IJS (Bug #1345).
+ - pdftops: Switch to Poppler as PDF renderer also for the
+ Apple LaserWriter 12/640, to work around a bug in the
+ printer's PostScript interpreter (Bug #1344).
+
+CHANGES IN V1.8.2
+
+ - Allow disabling dependencies on Ghostscript and Foomatic
+ (Bug #1342).
+ - cups-browsed: Optionally generate also local queues pointing
+ to remote raw queues. Usually only queues pointing to remote
+ queues with PPD/driver are created (Debian bug #814020,
+ Debian bug #756724).
+
+CHANGES IN V1.8.1
+
+ - cups-browsed: Do not disable queues which still have jobs (and
+ therefore cannot be removed) when avahi-daemon goes away, the
+ print server is most probably still available and printing can
+ be continued. Especially important on mobile devices where
+ avahi-daemon is shut down when the print dialog is closed (and
+ the job(s) still printing).
+
+CHANGES IN V1.8.0
+
+ - COPYING: Replaced the COPYING file by a file in Debian format,
+ derived from Debian's file but updated and corrected.
+ - braille: Added info about additional packages needed for Braille
+ printing to the README file.
+ - braille: Let the Braille filters use lou_translate of
+ liblouis if the more sophisticated file2brl of liblouisutdml
+ is not installed. This is decided on at run time, so later
+ installation of liblouisutdml will let the filters
+ automatically switch to file2brl.
+ - braille: Allow to build with Braille support also if
+ liblouis is not installed at build time.
+ - braille: Added checks for the presence of helper tools, to
+ get clear messages in the CUPS error_log if something is
+ missing.
+ - Fixed copyright headers of files inherited from CUPS or
+ derived from CUPS, pointing to COPYING as license info file,
+ removing Apple exceptions, removing hints that a missing
+ license info file can be found at www.cups.org, and removing
+ "$Id" SVN file ID placeholders.
+ - Updated COPYING file for missing implicitclass and beh
+ backends.
+
+CHANGES IN V1.7.0
+
+ - cups-browsed: Added possibility to trigger the auto shutdown
+ by the queues of cups-browsed being without jobs. Before
+ auto shutdown was only possible when all queues have gone
+ away. This allows auto shutdown on mobile devices where
+ avahi-daemon is also used for other things than printing.
+
+CHANGES IN V1.6.0
+
+ - cups-browsed: Fixed use of CUPS domain socket, both
+ detection during build process and permission check at
+ runtime.
+ - foomatic-rip: Fixed buffer overflow when reading environment
+ variables CUPS_FONTPATH, CUPS_DATADIR, and GS_LIB (Bug
+ #1336).
+ - beh: Introduced beh, the Backend Error Handler, a wrapper
+ backend to make handling of backend errors more
+ configurable. This backend is a C re-write of the beh
+ backend written in Perl which was part of the former
+ foomatic-filters package. Several people asked for beh
+ getting moved to cups-filters.
+ - braille: Make image printing working also if ImageMagick
+ generates formatted images without header.
+ - braille: If the user does not select a Braille translation,
+ let the embosser do the translation.
+ - cups-browsed: Added version info to help screen and start-up
+ in debug mode, call help screen also via "--version" option.
+ - cups-browsed: Minor improvements in help screen and man
+ page.
+
+CHANGES IN V1.5.0
+
+ - cups-browsed: Allow use of an alternative configuration file
+ via the "-c" command line option.
+ - cups-browsed: Allow supplying configuration settings via the
+ command line using the "-o" command line option.
+ - cups-browsed: Command line help via the "-h" or "--help"
+ command line option.
+
+CHANGES IN V1.4.0
+
+ - foomatic-rip: SECURITY FIX: Also consider the semicolon
+ (';') as an illegal shell escape character. Thanks to Adam
+ Chester (adam dot chester at pentest dot co dot uk) for the
+ hint (CVE-2015-8560).
+ - brftoembosser, imagetobrf, imagetoubrl, imageubrltoindexv3,
+ imageubrltoindexv4, textbrftoindexv3, textbrftoindexv4,
+ texttobrf, braille.convs, braille.types, generic-brf.drv,
+ indexv3.drv, indexv4.drv: Added support for Braille
+ embossing via CUPS. Text and even images can now be sent to
+ a Braille embosser like to a printer. Thanks to Samuel
+ Thibault (samuel dot thibault at ens-lyon dot org) for this
+ contribution.
+
+CHANGES IN V1.3.0
+
+ - cups-browsed: Added new BrowseFilter directive in
+ cups-browsed.conf. This directive allows filtering of the
+ remote printers to be accepted on most properties/metadata
+ supplied with the DNS-SD broadcasts. This allows, in
+ addition to BrowseAllow/BrowseDeny/BrowseOrder, to reduce
+ the amount of printers listed in print dialogs to a more
+ useful amount.
+ - cups-browsed: Added support for BrowseDeny and BrowseOrder
+ directives in cups-browsed.conf.
+ - cups-browsed: Let the BrowseAllow lines in cups-browsed.conf
+ also apply to remote printers discovered via DNS-SD.
+ - cups-browsed: Auto-create queues for PCL-5c/e printers but
+ not for HP inkjet printers (which also advertise themselves
+ as PCL printers).
+ - cups-browsed, sys5ippprinter: Recognize PCL-5c/e printers
+ not only by the application/vnd.hp-pcl MIME type but also by
+ application/pcl and application/x-pcl.
+
+CHANGES IN V1.2.0
+
+ - cups-browsed: When using IP-address-based device URIs via
+ the "IPBasedDeviceURIs" directive in cups-browsed.conf, add
+ two additional settings to restrict the used IP addresses to
+ either only IPv4 addresses or only IPv6 addresses.
+ - foomatic-rip: SECURITY FIX: Also consider the back tick
+ ('`') as an illegal shell escape character. Thanks to Michal
+ Kowalczyk from the Google Security Team for the hint
+ (CVE-2015-8327).
+
+CHANGES IN V1.1.0
+
+ - Version numbering scheme changed: Releases with feature
+ addition/change have the minor number increased now, pure
+ bug fix releases get the revision number increased, to make
+ use of the minor number which stayed zero all the time.
+ - cups-browsed: Added "DefaultOptions" directive to
+ cups-browsed.conf to allow defining default option settings
+ for local queues to be generated for newly appearing remote
+ printers.
+ - cups-browsed: Removed assert() calls which remained from
+ copy and paste in the very beginning of the development of
+ cups-browsed. assert() is only for use during debugging and
+ should not be used in production code.
+ - cups-browsed: Let option settings of a generated print queue
+ be saved before taking the queue down so that when the remote
+ printer appears again all user changes get restored, making
+ user changes permanent on generated queues.
+ - foomatic-rip: Fixed string length for shell path constant, to
+ work also with systems having longer paths (Bug #1325)
+ - cups-browsed: Added a mode in which IP-based device URIs
+ for the generation of local print queues are used, for
+ cases with problems in local host name resolution.
+ - foomatic-rip: Use -dFirstPage=... and -dLastPage=... only
+ if really needed (Bug #1324).
+ - cups-browsed, implicitclass: Make the load-balancing
+ configurable so that one can select whether the jobs get
+ queued up locally like in a CUPS class or whether they get
+ immediately distributed to the remote servers letting them
+ queue up there.
+
+CHANGES IN V1.0.76
+
+ - cups-browsed: Make build also working with BSD make (Bug
+ #1310).
+ - cups-browsed, implicitclass: Let the load-balancing queue up
+ the jobs in the local (generated) queue until a free (idle,
+ enabled, and accepting jobs) remote queue is found (check
+ every 5 sec if no free queue available). This gives a more
+ even distribution of the work amongst the servers and
+ protects against the case that a bunch of jobs gets
+ inaccessible or lost if one of the servers fails.
+ - cups-browsed: Let the load-balancing also check whether the
+ destination queue is actually accepting jobs.
+ - cups-browsed: If a generated queue is not removed on
+ shutdown of cups-browsed due to remaining jobs in it,
+ re-enable it in the next cups-browsed session even if it was
+ disabled by something other than cups-browsed.
+ - implicitclass: Clean up debug and error messages.
+ - implicitclass: Fix exit codes for immediate retry of jobs.
+ - cups-browsed: Make absence of CUPS notifications via D-Bus
+ non-fatal and fall back to the old behavior of cups-browsed
+ (fail-over instead of load balancing for equally-named
+ remote queues, do not remove generated queue if it is
+ default instead of default printer management). This solves
+ problems of CUPS and/or cups-browsed built without D-Bus
+ support or absence of D-Bus on the system (Bug #1316).
+ - cups-browsed: Do not use g_warning() function, sneaked in by
+ copy and paste of CUPS subscription functions.
+
+CHANGES IN V1.0.75
+
+ - texttopdf: Really support BoldItalic (original texttops just maps
+ BoldItalic to Bold).
+ - texttopdf: Fixed segfault when outputting BoldItalic (Bug #1314).
+
+CHANGES IN V1.0.74
+
+ - cups-browsed: Added NULL check when getting the notification of
+ a printer starting to process a job and checking whether this
+ printer is created by cups-browsed with the implicitclass:
+ backend (Ubuntu bug #1488524).
+ - backends: Include unistd.h and fcntl.h in backend-private.h for
+ all platforms, not only Linux, so that the backends build also
+ on non-Linux platforms (Bug #1308).
+ - cups-browsed: Do not schedule printers for update when they are
+ already marked as disappeared.
+ - cups-browsed: Added sanity checks when saving the default printer
+ selection in a file.
+ - cups-browsed, implicitclass: If remote queues disappear or
+ cups-browsed shuts down and a cups-browsed-generated queue still
+ has jobs and needs to be kept therefore, disable it and re-enable
+ it when cups-browsed starts again and/or the remote queue(s) re-
+ appear(s). This avoids repeated retries of the jobs while the
+ remote server is not available, causing unneeded system load and
+ battery consumption.
+ - cups-browsed: After polling info from remote CUPS servers to find
+ the best destination job, set the default CUPS server back to local.
+
+CHANGES IN V1.0.73
+
+ - cups-browsed: Added missing
+ utils/org.cups.cupsd.Notifier.xml file.
+
+CHANGES IN V1.0.72
+
+ - cups-browsed, implicitclass: Added load balancing
+ functionality. If there are several remote CUPS printers
+ with the same name, they for locally a cluster represented
+ by a print queue with this name. This printer prints through
+ a special backend (implicitclass) which makes cups-browsed
+ find the best destination remote queue (fewest jobs,
+ enabled) for this job.
+ - cups-browsed: Added protection against accidental deletion of
+ print queues generated by cups-browsed. These queues now get
+ automatically re-created.
+ - cups-browsed: Added LDAP support. Appropriately configured via
+ cups-browsed.conf remote printers made available via LDAP will be
+ looked up and local queues pointing to them created. Thanks to
+ Raphael Geissert (atomo64 at gmail dot com) for contributing this
+ patch (Debian bug #795185).
+ - cups-browsed: Introduced new handling for the default
+ printer using cache files. So we do not need to keep an auto-generated
+ queue because it is set as default printer. If the auto-generated
+ queue disappears, the old local printer is set as default again and
+ when it re-appears it returns to be the default printer.
+ - cups-browsed: Added infrastructure for subscribing to CUPS
+ notifications for things like improved default printer handling,
+ load balancing, ...
+ - foomatic-rip: Prevent crash when supplying "media" option with empty
+ value ("media=", Ubuntu bug #1479871).
+ - pdftoopvp: Adaptations to API changes on Poppler 0.34.0, note that
+ this patch disables color management in this filter. Thanks to
+ Vincent le Garrec and Andreas K. Huettel for the patch (Bug #1301,
+ Gentoo bug #554782).
+ - libcupsfilters, bannertopdf, foomatic-rip, gstoraster, pdftoijs,
+ sys5ippprinter, pdftoopvp, pdftops, pdftoraster, rastertoescpx,
+ urftopdf, texttopdf: Miscellaneous fixes for build compatibility with
+ different platforms, like config.h as very first include and so on.
+ Thanks to Richard Palo for the patch (Bug #1264).
+ - texttopdf: Request the generic 'monospace' font alias from fontconfig
+ instead of the hard-coded FreeMono. Thanks to Fabian Greffrath
+ (fabian at debian dot org) for the patch (Debian bug #788048).
+
+CHANGES IN V1.0.71
+
+ - texttopdf: The Page allocation is moved into textcommon.c, where it
+ does all the necessary checking: lower-bounds for CVE-2015-3258 and
+ upper-bounds for CVE-2015-3279 due to integer overflows for the
+ calloc() call initialising Page[0] and the memset() call in
+ texttopdf.c's WritePage() function zeroing the entire array. Thanks
+ to Tim Waugh from Red Hat for the patch.
+ - texttopdf: Upper-bounds checking (CVE-2015-3279).
+
+CHANGES IN V1.0.70
+
+ - texttopdf: Fixed buffer overflow on size allocation of texttopdf
+ when working with extremely small line sizes, which causes the size
+ calculation to result in 0 (CVE-2015-3258, thanks to Stefan
+ Cornelius fro Red Hat for the patch).
+ - cups-browsed: leak fixes
+ - cups-browsed: Further BrowseAllow fixing
+ - cups-browsed: BrowsePoll is an array of pointers, not structures,
+ so allocate room for the pointers
+ - cups-browsed: Prevent NULL dereference when handling BrowseAllow
+ without value
+ - cups-browsed: Use memory deallocation function corresponding to
+ allocation function used
+ - cups-browsed: Fixes for glib source handling (Red Hat bug #1228555)
+ - foomatic-rip: Allow using another shell than /bin/bash using the
+ "--with-shell=..." option for "./configure". Thanks to Leonardo
+ Taccari for the patch (Bug #1288).
+
+CHANGES IN V1.0.69
+
+ - cups-browsed: When generating a PPD for an auto-discovered IPP
+ network printer, create a "ColorModel" option only if valid
+ choices are reported for it by the IPP printer.
+ - cups-browsed: Updated PPD file generator for auto-generated queues
+ for IPP network printers from the CUPS 2.1.x upstream code, so that
+ floating-point numbers are written in a locale-neutral way
+ (CUPS STR #4579).
+ - cups-browsed: When checking whether a queue name already exists
+ as a locally defined queue, do case-insensitive comparing as for
+ CUPS printer names are case-insensitive. This assures that
+ already existing queues do never get overwritten.
+ - cups-browsed: Added "IPPPrinterQueueType Auto/PPD/NoPPD" directive
+ to cups-browsed.conf to allow controlling how cups-browsed
+ creates queues fr native IPP network printers: with PPD, with
+ System V interface script, or selecting automatically.
+ - pdftopdf: Center Landscape-oriented jobs correctly on the page
+ if the "fitplot" or "number-up" options are used (Bug #1284).
+ - pstopdf: Removed "-dUseCIEColor" from the Ghostscript command line.
+ In modern Ghostscript versions (9.11 and newer) it is recommended to
+ not use it with the pdfwrite and ps2write output devices any more.
+ - imagetopdf: Corrections in PDF output: Let evince display the PDF
+ with the correct size including margins and let ghostscript not
+ complain about an invalid xref entry.
+ - cups-browsed: Do not add options to the System V interface script
+ which calls sys5ippprinter but set the options as defaults for the
+ CUPS queue in printers.conf.
+ - cups-browsed: When auto-generating a PPD-less print queue for an
+ IPP network printer, determine default page size, unprintable margins,
+ and color space from the printer via an IPP request.
+ - imagetopdf: Debug logging should be only controlled by the LogLevel
+ of CUPS, not by an awkward build time switch.
+ - cups-browsed: Determine from the TXT records of the Bonjour broadcast
+ of an IPP network printer whether it has color and duplex
+ capabilities and if yes, let auto-generated PPD-less print queues
+ use appropriate command line options to make use of these
+ capabilities.
+ - imagetopdf: Make this filter also work with auto-generated PPD-less
+ print queues for IPP network printers.
+ - sys5ippprinter: Renamed from pdftoippprinter to reflect that
+ it is a System 5 interface script and does not accept only
+ PDF as input.
+ - pdftoippprinter: Support also PWG Raster and JPEG as input formats
+ so that an auto-generated, PPD-less queue for an IPP printer emulates
+ an IPP Everywhere printer.
+
+CHANGES IN V1.0.68
+
+ - cups-browsed: Numeric IDs for GSources of the glib event
+ loop must be positive integers greater than zero according
+ to the documentation of the g_source_get_id() function.
+ Taken care of this at all places.
+ - cups-browsed: Added conditionals so that it also builds with
+ CUPS 1.5.x (but then withou support for automatically creating
+ queues for IPP network printers). Thanks to Johannes Meixner from
+ SUSE for the patch (Bug #1268).
+ - Ricoh-PDF_Printer-PDF.ppd: Added PPD file for Ricoh's PDF printers
+ (experimental). Thanks to Ulrich Wehner from Ricoh for the file.
+
+CHANGES IN V1.0.67
+
+ - cups-browsed: Use g_source_remove() instead of g_source_destroy()
+ for killing auto shutdown timers (Ubuntu bug #1427344).
+
+CHANGES IN V1.0.66
+
+ - cups-browsed: SECURITY FIX: Fixed a bug in the remove_bad_chars()
+ failing to reliably filter out illegal characters if there are two
+ or more subsequent illegal characters, allowing execution of
+ arbitrary commands with the rights of the "lp" user, using forged
+ print service announcements on DNS-SD servers (Bug #1265).
+ - pdftoopvp: Added conditionals to also build with Poppler 0.31.0
+ and newer. Thanks to Armin K. (krejzi at email dot com) for the
+ patch (Bug #1254).
+
+CHANGES IN V1.0.65
+
+ - cups-browsed: Listen for NetworkManager changes (Red Hat bug #975933).
+ - cups-browsed: Fix for memory leak introduced in BZR rev 7059.
+ - cups-browsed: Memory leak/uninit fixes.
+ - cups-browsed: Cache prepared browse data to send.
+ - cups-browsed: Only get local notifications once per BrowsePoll run.
+ - cups-browsed: Fix BrowsePoll now notifications work properly. Need
+ to maintain a list of printers to keep alive for the case of there
+ being no notifications of changes.
+ - cups-browsed: Use local browsepolling for getting initial printer
+ list.
+ - cups-browsed: Ignore browse packets for deleted printers.
+ - cups-browsed: Cache connection to local cupsd.
+ - cups-browsed: Use notifications to track local printers.
+ This avoids expensive calls to cupsGetDests().
+ - cups-browsed: Manage subscriptions for local browsepolling.
+ - cups-browsed: Track notify-sequence-number for notifications.
+
+CHANGES IN V1.0.64
+
+ - cups-browsed: Added PPD file generator for IPP Everywhere
+ printers. If auto-setup of discovered IPP printers is
+ activated ("CreateIPPPrinterQueues Yes" in
+ cups-browsed.conf), the printer provides suitable capability
+ information via a Get-Printer-Attributes IPP call, and
+ prints PWG or PostScript input, a PPD is auto-generated
+ based on the Get-Printer-Attributes IPP response. Otherwise
+ a System-V interface script is used as befreo. Advantage of
+ the PPD file is that current print dialogs aloow access to
+ the options, no IPP request done by the dialog is
+ required. The PPD generator code is borrowed from the CUPS
+ 2.1.x development code repository. It will perhaps be
+ removed in the future when CUPS provides proper API function
+ for its PPD generator.
+
+CHANGES IN V1.0.63
+
+ - foomatic-rip: Added hint to man page that direct, spooler-less mode
+ is mainly for testing and debugging (Bug #1253).
+ - foomatic-rip: Added a symlink of the filter to the binary executable
+ directory (usually /usr/bin), so that LSB compliance test scripts
+ work (Bug #1255).
+ - cups-browsed: Fixed CUPS Browsing timeouts. Thanks to Tim
+ Waugh from Red Hat for the patch (Bug #1252, Red Hat bug
+ #1189254).
+
+CHANGES IN V1.0.62
+
+ - cups-browsed: Allow underscore characters in print queue names.
+ Thanks to Tim Waugh from Red Hat for the bug report (Bug
+ #1241).
+ - pdftops: Apply workarounds for Kyocera also to Utax printers
+ as Utax uses hard- and software from Kyocera. Thanks to Edward
+ Huang from Kyocera.
+ - cups-browsed: Added support for "BrowseAllow All" in the
+ cups-browsed.conf file.
+ - cups-browsed: Reorder inclusion of headers for compatibility
+ with NetBSD (Bug #1235).
+ - imagetopdf, pdftopdf: Correct handling of hardware copies in
+ PJL/JCL and/or when the PPD file has a "Copies" option.
+
+CHANGES IN V1.0.61
+
+ - cups-browsed: Fixed memory leak when a
+ cups-browsed-generated print queue is the default
+ printer. Thanks to Tim Waugh from Red Hat for the patch (Red
+ Hat bug: #1119290).
+ - cupsfilters.drv, *-PDF.ppd, textonly.ppd: Added
+ "*cupsFilter2: ..." lines to the PPD files to support
+ data-format-specific behavior of backends, especially of the
+ IPP backend.
+
+CHANGES IN V1.0.60
+
+ - cups-browsed, pdftoippprinter: Do not confuse the PDL "PCLm"
+ with "PCL". The former is a proprietary, PDF-based raster
+ format and has nothing to do with PCL.
+ - cupsfilters.drv: Corrected the CMD: field of the device ID,
+ it must read "PWGRaster" there to conform to the PWG standard.
+
+CHANGES IN V1.0.59
+
+ - cupsfilters.drv: Added PPD file for a Generic IPP Everywhere
+ Printer, generating PWG Raster output.
+ - gstoraster, pdftoraster, imagetoraster: Allow PWG Raster
+ output with print queues using a PPD file, using the new
+ "PWGRaster" PPD attribute.
+ - pdftoraster: Removed "cm_disabled" flag in selectConvFunc()
+ - libcupsfilters: Allowed color management to continue while
+ invalid input
+ - rastertopdf: Streamlined PDF conversion code
+ - rastertopdf: Invert all CUPS_CSPACE_K documents by default
+ - foomatic-rip: Clean trailing white space from PPD file lines to
+ avoid a segfault caused by it (Bug #1227).
+
+CHANGES IN V1.0.58
+
+ - pdftoraster: Changed ICC profile get function to accept a
+ PPD fallback profile.
+ - pdftoraster: Fixed handling of cupsColorSpaces 18,19,20.
+ - rastertopdf: Added test feature to force color management if
+ "profile=" option is specified.
+ - rastertopdf: Grayscale color conversion now properly inverts
+ bits.
+ - rastertopdf: Code cleanup for prepare_pdf_page().
+ - rastertopdf: Implemented basic 8bit->8bit color space
+ conversions.
+ - rastertopdf: Added black point compensation.
+ - rastertopdf: Added handling of color rendering intent.
+ - gstoraster, imagetoraster, pdftoraster, rastertopclx,
+ rastertopdf, foomatic-rip: Use color management functions in
+ libcupsfilters.
+ - libcupsfilters: Modified code formatting and documentation in
+ the color management functions.
+ - libcupsfilters: Fixed string handling and added debug log
+ messages in the color management functions.
+ - libcupsfilters: Fixed Adobe RGB matrix for proper rendering
+ (transpose)
+ - libcupsfilters: Moved color management functions from the
+ individual filters to the libcupsfilters library.
+
+CHANGES IN V1.0.57
+
+ - rastertopclx: Fixed implicit declaration of
+ colord_get_inhibit_for_device_id.
+ - Build system: Explicitly link to libm as -lm was dropped
+ from cups-config --libs.
+ - libcupsfilters, foomaticrip, gstoraster, imagetoraster,
+ pdftoraster, rastertopclx, rastertopdf: Handle absence of
+ colord or D-Bus gracefully (Ubuntu bug #1356405).
+
+CHANGES IN V1.0.56
+
+ - rastertopdf: Some code polishing and removal of now unneeded
+ functions
+ - rastertopdf: Reduced color space handling to only
+ PWG-supported color spaces
+ - rastertopdf: Added colorspace calibration function; included
+ optional "/Alternate" PDF key for ICC profile embedding
+ - rastertopdf: Colorspace sRGB now embeds srgb icc profile;
+ implemented ICC Profile embedding (PDF 1.3 spec)
+ - rastertopdf: Added basic color calibration
+ - rastertopdf: Implemented ICC Profile creation code for IPP
+ Everywhere (from PWG raster)
+ - pdftoraster: Added colord handling of ICC profiles
+ - kmdevices.cpp/.h: Added interface for Kolor Manager
+ - cups-browsed: Do not consider a remote CUPS queue as raw if
+ the TXT record is NULL as for queues broadcasted by the
+ legacy CUPS method the TXT record does not exist. Now
+ consider a queue with NULL TXT record only as raw if the
+ domain entry is not empty (which tells that the queue is
+ Bonjour-broadcasted (Bug #1223).
+ - cups-browsed: Do also not mark a discovered printer as
+ already provided by another server when the other server's
+ queue has "unconfirmed" status. Mark the other queue with
+ "disappeared" or "unconfirmed" status as duplicate of the
+ discovered printer so that the new queue for the discovered
+ printer does not get removed when the entry for the other
+ queue times out.
+
+CHANGES IN V1.0.55
+
+ - pdftopdf: Fixed manual duplex by adding a blank page to evn
+ pages if the total number of pages of the document is
+ odd. Otherwise the last page of the document would stay in
+ the input tray. This fixes also a side effect as the set of
+ even pages reducing to a zero page job if the job consists
+ of only one page, making Poppler's pdftops error out (Ubuntu
+ bug #1340435).
+ - cups-browsed: Do not mark a discovered printer as already
+ provided by another server when the other server's queue has
+ "disappeared" status. This queue can be from the same server
+ before it changed its name.
+ - cups-browsed: Do not create a local queue pointing to a
+ remote raw queue (Ubuntu bug #1335211).
+ - foomatic-rip, imagetoraster, pdftoraster, rastertopclx,
+ rastertopdf: Added colord "device_inhibit" support for
+ color-managed filters.
+ - foomatic-rip: Let it also build correctly on systems which
+ already provide the strlcat() and strlcpy() functions, like
+ Mac OS X. Thanks to Matt Broughton for reporting this
+ (bug #1215).
+ - bannertopdf: Added support for PPD-less printing, especially
+ one gets a useful test page with PPD-less queues now.
+ - bannertopdf: Fixed "Printer Location" and "Driver Version"
+ entries on the test page/the banners.
+ - bannertopdf: Added new PDF template files which contain the
+ text strings appropriate to the banners, before the banners
+ were all equal, without text. Thanks to Johannes Meixner
+ from SUSE/Novell for this fix (Bug #1209).
+ - bannertopdf: Fixed Makefile to mark it dependent on
+ libfontembed.la. Thanks to Tim Waugh from Red Hat for the
+ patch (Red Hat bug #1106101).
+ - pstopdf: Use "grep -E" instead of "grep -P" as the latter
+ generates executable code and executes it, requiring
+ "execmem" privileges which could be not available in some
+ security policies. Thanks to Tim Waugh from Red Hat for the
+ patch (Red Hat bug #1079534).
+ - foomatic-rip: NetBSD does not provide a mkstemps() function,
+ use appropriate workaround then (Bug #1211).
+ - cups-browsed: Reorder inclusion of headers for compatibility
+ with NetBSD (Bug #1212).
+ - pdftoraster: Fixed segfault caused by introduction of
+ "no-color-management" option (Bug #1214).
+ - libcupsfilters: Let cupsRasterParseIPPOptions() also accept
+ "pwg-raster-document-type" settings with hyphen between
+ color space name and color depth.
+
+CHANGES IN V1.0.54
+
+ - pdftoraster: Support for output in the color spaces 18
+ (CUPS_CSPACE_SW, sGray), 19 (CUPS_CSPACE_SRGB, sRGB), and 20
+ (CUPS_CSPACE_ADOBERGB, Adobe RGB). No color management
+ appropriate to these color spaces is added yet.
+ - foomatic-rip, gstoraster, imagetoraster, pdftoraster,
+ rastertopclx: added boolean option "no-color-management" to
+ suppress all forms of color correction when
+ color-calibrating the printer.
+ - pdftops: Default to "hybrid" setting for the PDF->PostScript
+ renderer.
+ - pdftoraster: Produce correct (compressed) PWG Raster output
+ when requested by using the correct mode in
+ cupsRasterOpen().
+ - rastertopdf: Added new filter to convert PWG Raster input
+ into a PDF file (using QPDF). This filter makes CUPS
+ supporting the PWG Raster input format which is required to
+ be supported by IPP Everywhere printers, making a shared
+ CUPS queue emulating an IPP Everywhere printer. This is a
+ first implementation which supports the black, RGB, CMYK,
+ sGray, sRGB, and Adobe RGB color spaces (all mapped to
+ DeviceGray, DeviceRGB, and DeviceCMYK resp. in the PDF
+ output) with 1, 8, and 16 bits per component color
+ depth. sGray, sRGB, and Adobe RGB are currently also mapped
+ to DeviceGray and DeviceRGB and do not have the correct
+ color management yet, so color output is not absolutely
+ correct. Note that mime.types of CUPS up to 1.7.2 has a bug
+ which prevents PWG Raster to be recognized, the
+ "priority(100)" of the rule needs to be changed to
+ "priority(150)".
+ - foomatic-rip: Corrected declaration of print_pdf() function in
+ pdf.h file (Debian bug #748028).
+ - foomatic-rip: Let it also build with uclibc which does not
+ provide the mkstemps() function. Thanks to Andreas K.
+ Huettel for the patch (Gentoo bug #509884).
+ - cups-browsed: Create local queues also to access classes on
+ remote CUPS servers (Ubuntu bug #1313741).
+ - cups-browsed: Let a newly discovered printer not only
+ overtaking an existing printer entry if it is from the same
+ host (usually IPP -> IPPS) or without host entry
+ (unconfirmed local queue from previous cups-browsed session)
+ but also if it is marked disappeared. So printer entries get
+ correctly migrated when things like a host name change of
+ the remote server happen.
+ - cups-browsed: Always do case-insensitive comparing of
+ strings, as CUPS queue names and URIs are case-insensitive
+ (CUPS STR #4411).
+
+CHANGES IN V1.0.53
+
+ - foomatic-rip: Fixed segfault when creating log file (Bug
+ #1206).
+ - cups-browsed: SECURITY FIX: Fix on usage of the
+ "BrowseAllow" directive in cups-browsed.conf. Before, if the
+ argument of a "BrowseAllow" directive is not understood it
+ is treated as the directive not having been there, allowing
+ any host if this was the only "BrowseAllow" directive. Now
+ we treat this as a directive which no host can fulfill, not
+ allowing any host if it was the only one. No "BrowseAllow"
+ directive means access for all, as before (Bug #1204).
+ - cups-browsed: SECURITY FIX: Further improvement on the fix
+ in 1.0.51 as it was insufficient. In addition, some fixes
+ against OOB access are done. Thanks to Sebastian Krahmer for
+ the patch (SUSE/Novell bug #871327).
+
+CHANGES IN V1.0.52
+
+ - texttopdf: Make sure that margin changes for prettyprint
+ get applied.
+ - texttopdf, imagetopdf, imagetoraster: Range-check paper
+ dimensions and margins taken from the PPD file and correct
+ them if needed (Bug #1195).
+
+CHANGES IN V1.0.51
+
+ - cups-browsed: SECURITY FIX to prevent arbitrary code
+ injection into the System V interface scripts generated for
+ queues for discovered native IPP printers by a malicious IPP
+ print service with forged make/model and/or PDL string.
+
+CHANGES IN V1.0.50
+
+ - pdftops: Let old HP LaserJet printers (model number without
+ letter, like "LaserJet 3" or "LaserJet 4000") use Poppler
+ instead of Ghostscript (Debian bug #742765).
+ - pdftops: Improved workaround for Toshiba printers. Instead
+ of using Poppler do not emit TrueType fonts with Ghostscript
+ (Ubuntu bug #998087).
+ - cups-browsed: Build the device URIs for all local queues we create
+ with the CUPS library function httpAssembleURIf() for proper
+ percent escaping of characters which are not allowed in URIs
+ (Bug #1187).
+
+CHANGES IN V1.0.49
+
+ - pdftops: Use Poppler also for Toshiba printers (Ubuntu bug
+ #998087).
+ - pdftops: Fixed typo which always made PostScript level 2 being
+ generated when using Poppler's pdftops (Ubuntu bug #1294370).
+
+CHANGES IN V1.0.48
+
+ - cups-browsed: Fix for a crash which happens on Bonjour reports of
+ printers without "product", "usb_MDL", and "ty" fields in the
+ text record (Ubuntu bug #1284834).
+ - cups-browsed: In README and in the sample startup scripts/configs
+ for System V Init and Upstart taken into account the fact that it
+ is not required any more to start avahi-daemon before starting
+ cups-browsed.
+
+CHANGES IN V1.0.47
+
+ - pdftoopvp: SECURITY FIX for CVE-2013-6474, CVE-2013-6475,
+ and CVE-2013-6476: Introductionof gmallocn and gmallocn3
+ to protect against arbitrary code execution with the
+ privileges of the "lp" user via malicious PDF files. Also
+ restrict the directory from where OPVP drivers can get
+ loaded.
+ - urftopdf: SECURITY FIX for CVE-2013-6473: Two heap-based
+ buffer overflow flaws in urftopdf. If a malicious URF file
+ were processed it could lead to arbitrary code execution
+ with the privileges of the "lp" user.
+ - pdftopdf: Fixed typo in initialization which sets the default
+ value page border to an undefined value. Thanks to Helge
+ Blischke for the patch.
+ - cups-browsed: Check for changes of the URI of a queue which
+ we have created and correct the URI if needed, especially if
+ a queue was not removed on shutdown of cups-browsed (default
+ printer or still having jobs) and before restart of
+ cups-browsed the server's DNS-SD-provided has changed.
+ - bannertopdf: Support PDF forms as banner template. This allows
+ especially internationalized banner pages. Forms can contain
+ fields for any CUPS/IPP value and get automatically filled
+ Thanks to Andrew V. Stepanov from ALT Linux (Bug #1170,
+ also first step to fix Ubuntu bug #1196986).
+
+CHANGES IN V1.0.46
+
+ - gstoraster: Ignore SIGCHLD, rely on waitpid instead. Thanks
+ to Lauri Tirkkonen (Bug #1184).
+ - gstoraster: Fix two instances of insufficient EINTR handling.
+ Thanks to Lauri Tirkkonen (Bug #1184).
+
+CHANGES IN V1.0.45
+
+ - cups-browsed: Under Upstart load the AppArmor profile
+ (Ubuntu bug #1276630).
+ - cups-browsed: Added auto-shutdown feature for on-demand use
+ of cups-browsed (for example on mobile devices). With auto
+ shutdown active, cups-browsed terminates after a certain
+ time interval (30 sec by default) without having any remote
+ printer to make available locally. The mode can be turned
+ on, turned off (default) or set to automatically be off
+ while avahi-daemon is running an on otherwise (controlled by
+ avahi-daemon running on-demand). The mode and the timeout
+ interval can be selected by command line options, the
+ configuration file, and sending signals to cups-browsed
+ (on/off only).
+ - cups-browsed: To make Bonjour-discovered printers locally
+ available avahi-daemon does not need to be started before
+ cups-browsed and does not need to stay continuously running
+ while cups-browsed is running. Bonjour-discovered printers
+ are now added whenever avahi-daemon starts and removed
+ whenever avahi-daemon stops and cups-browsed keeps
+ running. This makes it easier to use cups-browsed in
+ different system-configurations and also on systems with
+ daemons running on-demand (like mobile systems).
+ - foomatic-rip: Fixed pid_t/int function prototype mismatch
+ (Bug #1182).
+ - Fixed --with-pdftops-path and --with-pdftocairo-path options
+ in ./configure (Bug #1181).
+ - foomatic-rip: Do not use PATH_MAX for the length of static
+ strings which are supposed to hold a command line. Use our
+ own CMDLINE_MAX constant to set them to a length of 65535
+ bytes (Ubuntu bug #1019662, Debian bug #738440).
+ - pdftops: Log command lines of renderer (Ghostscript, pdftops,
+ pdftocairo, acroread) and of pstops in CUPS' error_log (in
+ debug mode).
+
+CHANGES IN V1.0.44
+
+ - README: Documented the "hybrid" choice for the PDF renderer
+ in the pdftops filter.
+ - pdftoippprinter: Handle missing Ghostscript/Poppler for all
+ output formats.
+ - cups-browsed: Minor corrections in the error messages.
+ - gstopxl: Support for PPD-less printing. Resolution,
+ InputSlot, Duplex, and ColorModel are set also without PPD
+ file now.
+ - Added another sample PPD file for a native PDF printer,
+ Fuji_Xerox-DocuPrint_CM305_df-PDF.ppd. Thanks to Adrian
+ Johnson for contributing this PPD file.
+
+CHANGES IN V1.0.43
+
+ - cups-browsed: When automatically setting up a PPD-less print
+ queue for an IPP network printer add make/model info as an
+ additional "make-and-model" command line option to the call
+ of the pdftoippprinter filter, this way filters can do
+ make/model-specific exceptions (quirk rules).
+ - pdftopdf: Take page size from the command line if not
+ already given by the PPD file, this way
+ "fitplot"/"fit-to-page" also works with PPD-less printing.
+ - libcupsfilters: cupsRasterParseIPPOptions() did not set
+ sRGB color space.
+ - libcupsfilters: cupsRasterParseIPPOptions() did not set
+ Tumble with "Duplex=DuplexTumble".
+ - pdftopdf: Fixed software copy generation logic for printers
+ with hardware copy generation, but without collate support
+ (Ubuntu bug #1259240).
+ - pdftops: Let Ghostscript output PostScript level 3 also for
+ PPD-less printing, but not for HP lasers or when make/model
+ info is not supplied.
+ - cups-browsed: removed duplicate definition of ippSetVersion.
+ - foomatic-rip: Take PATH_MAX constant from limits.h if
+ available instead defining it's own version conflicting with
+ kfreebsd. Thanks to Peter Green for the patch (Debian bug
+ #731658).
+ - pdftops: Ignore "landscape", "orientation-requested",
+ "fit-to-page", and any page geometry options. The first two
+ do not make sense on PDF input and therefore should only be
+ used in ...topdf filters used before pdftopdf, the others
+ are already taken care of by pdftopdf so that pdftops gets
+ pages with print-ready page geometry.
+ - pdftops: Added "-nocenter" to the call of "pdftops
+ -origpagesizes" (Poppler/freedesktop.org bug #72312,
+ comments #6 and #7).
+ - pdftopdf: If there is no PPD file or no
+ "*LandscapeOrientation:" keyword in the PPD file, rotate
+ counterclockwise, not clockwise to fit a landscape-oriented
+ page on a portrait-oriented sheet (See
+ Poppler/freedesktop.org bug #72312, comment #6).
+ - pstopdf: Support for the "landscape" and
+ "orientation-requested" options (Ubuntu bug #1243484).
+ - pdftops: Support for PPD-less printing on PostScript
+ printers: duplex, resolution, input tray, color mode, and
+ make/model (for quirk rules) can now be supplied by the
+ command line, pdftopdf takes care of the page geometry.
+ - libcupsfilters: cupsRasterParseIPPOptions() allows
+ specifying resolutions without unit now, assuming dpi then
+ (example: "600x600").
+ - Fixed "--with-cups-rundir" and "--with-cups-domainsocket"
+ options in configure (Bug #1174).
+ - pdftops: After fixing the output of rotated PDF pages
+ (usually landscape-oriented pages rotated by pdftopdf) in
+ Poppler (Poppler/freedesktop.org bug #72312) corrected the
+ use of "pdftops -origpagesizes" in pdftops appropriately
+ (Red Hat bug #768811).
+
+CHANGES IN V1.0.42
+
+ - pdftoippprinter: Check also the presence of Ghostscript and
+ use pdftoraster if Ghostscript is missing.
+ - gstoraster: At build time use the path for Ghostscript which
+ our build system already finds for pdftops.
+ - pdftoraster: Take into account rotate field in PDF header,
+ when pdftopdf rotates a page to fit the paper it sets the
+ rotate field and does not swap the width and height entries.
+ - pdftoippprinter: Made PCL 5c/e printing working correctly,
+ by first adding support for unprintable margins and
+ defaulting to 12pt margins if no margin info is supplied,
+ and second, by doing color printing always in RGB color
+ space.
+ - rastertopclx: Improved support for PPD-less printing,
+ allowing color printing with (s)RGB color space. Output is
+ in sRGB then.
+ - rastertopclx: Determine page size and select correct PCL
+ command for the page size more reliably, especially for
+ landscape-oriented pages.
+ - gstoraster, pdftoraster: Do correct PWG Raster output, allow
+ switching to PWG Raster via "media-class=PwgRaster" option
+ and CUPS Raster via "media-class=". Default for PPD-less
+ printing is PWG Raster.
+ - gstoraster, pdftoraster: Support applying unprintable
+ margins for PPD-less mode with CUPS Raster output.
+ - libcupsfilters: Added support for "media-left-margin",
+ "media-right-margin", "media-bottom-margin", and
+ "media-top-margin" IPP options to specify unprintable
+ margins in 1/100th of a mm, to allow PPD-less printing with
+ unprintable margins (esp. PCL 5c/e with rastertopclx).
+ - libcupsfilters: Do not set "MediaClass" to "PwgRaster" when
+ we request a CUPS Raster header and not a PWG Raster header.
+ - libcupsfilters: Fixed typo in a debug message in the colord
+ support part.
+ - cupsfilters.convs: Corrected cost factor of
+ vnd.cups-postscript -> vnd.cups-raster conversion with
+ gstoraster, so that input data of the type
+ application/vnd.adobe-reader-postscript is converted
+ correctly (not via pstotiff). Thanks to Tim Waugh from Red
+ Hat for this patch
+ - cups-browsed: Fixed several memory leaks by adding missing
+ free() calls and removing an unneeded strdup(). Thanks to
+ Jaromir Koncicky from Red Hat for the patch (Red Hat bug
+ #1027317).
+ - Backends parallel and serial: Fixed logical expressions for
+ error handling (Bug #1172).
+ - libcupsfilters: Moved filter/colord.[ch] into the library as
+ this code is now used by both gstoraster and foomatic-rip.
+ - libcupsfilters: Made the names of the flags to tell that the
+ header is already included unique in all API header files.
+ - foomatic-rip: Moved foomatic-rip's upstream home from the
+ foomatic-filters package to cups-filters, to make it easier
+ for distributions to ship and maintain a complete printing
+ stack and also to make upstream maintenance and development
+ easier.
+ - foomatic-rip: Removed support for all the non-CUPS printing
+ environments as they are discontinued upstream. Now
+ foomatic-rip only works as a CUPS filter and in a spooler-less
+ direct mode, where the latter is mainly for testing and
+ debugging. Thanks to Anshul Kushwaha (anshulkushwaha1 at gmail
+ dot com) for doing this as a Google Summer of Code 2013 project.
+ - foomatic-rip: Eliminated compiler warnings.
+ - foomatic-rip: fixed "endswith()" string utility function.
+ - foomatic-rip: Removed unneeded HAVE_DBUS conditionals.
+ - gstoraster: Fixed build system for gstoraster use D-Bus for
+ colord support.
+ - libcupsfilters: Recognize more Adobe-generated CMYK JPEGs to
+ take into account their inverted colors (Bug #1169).
+ - pdftopdf: When checking whether double-sided printing is
+ chosen, do not only check for the choice names "DuplexNoTumble"
+ and "DuplexTumble" but also for "LongEdge", "ShortEdge",
+ "Top", and "Bottom", as CUPS does (Bug #1167).
+
+CHANGES IN V1.0.41
+
+ - cups-browsed: Added support for automatic PPD-less setup of
+ print queues for IPP printers discovered on the network via
+ Bonjour. Supported are printers with known languages (PWG
+ Raster, PDF, PostScript, PCL XL, PCL 5c/e), especially also
+ IPP Everywhere printers. This functionality is especially
+ ment for mobile devices to be able to print without printer
+ setup tool and without printer driver/PPD collection.
+ - cups-browsed: Fixed a Valgrind-reported issue.
+ - pdftoippprinter: New filter for PPD-less printing. The filter
+ will be configured as System-V interface script for a print
+ queue for a discovered IPP network printer generated by
+ cups-browsed.
+ - rastertopclx: Added support for PPD-less printing. Without
+ PPD the filter generates PCL 5e.
+ - cups-browsed: Fixed socket leaks in recent IPP subscriptions
+ changes. Thanks to Tim Waugh from Red Hat for the patch (Red
+ Hat bug #1021512).
+
+CHANGES IN V1.0.40
+
+ - pdftops: Introduced new "hybrid" renderer: Here usually
+ Ghostscript is used, but if the printer is a Brother,
+ Minolta, or Konica Minolta Poppler's pdftops gets used. This
+ is a quirk rule to work around bugs in the PS interpreters
+ of the printers.
+ - Fixed format string issues and added __attribute__ wording
+ to printf-like functions to catch any regressions. Thanks to
+ Tim Waugh from Red Hat for the patch.
+
+CHANGES IN V1.0.39
+
+ - pdftops: Fix for landscape PDF handling. Do not use the
+ command line options "-origpagesizes" and
+ "-choosePaperByPDFPageSize" of Poppler's pdftops utility on
+ already processed PDF data. Thanks to Tim Waugh from Red Hat
+ for the patch.
+ - cups-browsed: Improve the efficiency of BrowsePoll by using
+ IPP notifications when possible. It falls back to the
+ previous behaviour if it is not possible to use this
+ optimization. Thanks to Tim Waugh from Red Hat for the patch.
+
+CHANGES IN V1.0.38
+
+ - pdftops: Added "-dNOINTERPOLATE" to the Ghostscript command line
+ for quicker processing of embedded bitmaps.
+ - pstopdf: Added "-dUseCIEColor" to the Ghostscript command line
+ to assure compatibility with newer Ghostscript versions (9.08
+ and newer).
+
+CHANGES IN V1.0.37
+
+ - Added example configuration files for systemd and Upstart. Thanks
+ to Tomáš Chvátal for the systemd file.
+ - Build system: Make sure that gstoraster gets linked against the
+ libcupsfilters of the currently built package and not of the
+ system. Thanks to Tomáš Chvátal.
+ - cupsfilters.convs: Reworked the cost factors of the filters to
+ avoid bogus filter chains like pstotiff|imagetopdf instead of
+ pstopdf|pdftopdf for PostScript->PDF. Thanks to Tim Waugh from
+ Red Hat for the report.
+ - pdftopdf: Accept additional command line options for PPD-less
+ printing.
+ - cups-browsed: Fixed building with CUPS 1.5.x and older,
+ ippSetVersion() was missing under the accessor function definitions
+ for backward compatibility.
+
+CHANGES IN V1.0.36
+
+ - Fixed libdl detection in configure. Thanks to Andreas Huettel and
+ Yuta Satoh (Gentoo bug #478642).
+ - cups-browsed: Allow BrowsePoll operation also access print queues
+ on older CUPS servers. Thanks to David Mohr for the patch.
+ - cups-browsed: Assure that it always applies to the local CUPS
+ daemon and never to a remote one specified via client.conf
+ (Ubuntu bug #1207203).
+ - pdftoopvp, pdftoijs, pdftoraster, bannertopdf: Made code working
+ with Poppler 0.24.x (Bug #1144).
+ - gstoraster: Silenced compiler warnings.
+ - gstoraster, pdftoraster: Added support for PPD-less printing
+ controlled by IPP attributes (CUPS 1.7.x+ only).
+ - gstoraster, gstopxl: Moved these filters from Ghostscript to
+ cups-filters as upstream home.
+ - libcupsfilters: Added new cupsRasterParseIPPOptions() API
+ function for PPD-less printing controlled by IPP attributes
+ (raster.h, CUPS 1.7.x+ only).
+ - pdftopdf: Added support for page labels. "page-label" option and
+ "CLASSIFICATION" environment variable. Thanks to Tim Waugh from
+ Red Hat for the patch.
+ - pdftops: If one or more of the PDF-to-PS renderers (Ghostscript,
+ Poppler pdftops, Poppler pdftocairo, acroread) is not installed
+ at build time, pre-fill the appropriate executable's path with the
+ executable name to allow the use of this renderer when it gets
+ installed later (Debian bug #716842).
+ - cups-browsed: Do not resolve host names of remote printers discovered
+ via CUPS broadcasts (Bug #1141).
+ - Added man pages for cups-browsed and cups-browsed.conf. Thanks to
+ Brian Potkin for the contribution (Debian bug #714460).
+ - Install also escp.h, it is useful for .drv files.
+
+CHANGES IN V1.0.35
+
+ - pdftoraster: Silenced compiler warning (Bug #1092).
+ - bannertopdf: Fixed typo which prevented the host name to be shown
+ (Bug #1115).
+ - README: Fixed info about the PPD keyword cupsManualCopies (Bug
+ #1086).
+ - Modified the cost factors of the filters to avoid unneeded PDF
+ conversion detours when the input data is PostScript. Instead of
+ pstopdf->pdftopdf->pdftops and pstopdf->pdftopdf->gstoraster we
+ get pstops and pstops->gstoraster now (Bug #1138).
+ - pdftops: Added experimental support for pdftocairo as PDF renderer.
+ Note that PostScript level 1 output and PDF input with color
+ spaces other than DeviceRGB, DeviceGray, sRGB or sGray is not
+ supported. PDFs generated by Cairo (for example when printing from
+ evince) uses only supported color spaces. Thanks to James Cloos
+ for the patch (Bug #1139).
+ - cups-browsed: Changed default of browsing protocols fron none to
+ both DNS-SD and CUPS.
+ - pdftops: Let Poppler generally generate PostScript level 3 if the
+ PPD identifies the printer as PS3 printer, make an exception of
+ sending PostScript Level 2 only for HP's laser printers, to not
+ compromise print quality and performance on all PS3 printers only
+ due to some buggy HP models (Debian bug #712949, see also Ubuntu bug
+ #277404).
+ - Install pcl.h, it is needed by cupsfilters.drv. Thanks to Jiri
+ Popelka from Red Hat for the patch (Bug #1133).
+ - Make cups-filters building with automake 1.13. Thanks to Andreas K.
+ Huettel (dilfridge) on IRC.
+ - libcupsfilters, libfontembed, pdftopdf, texttopdf, cups-browsed:
+ Fixed several resource leaks and other problems. Thanks to Jiri
+ Popelka from Red Hat for the patches (Bug #1116).
+
+CHANGES IN V1.0.34
+
+ - cups-browsed: Fixed build with OpenBSD (Bug #1103).
+ - pdftopdf: Enabled hardware copy generation, if available.
+ - pdftopdf: Fixed evenDuplex logic.
+ - cups-browsed: If a queue left over from the last session
+ gets confirmed, fill in the data structure with the Bonjour
+ parameters, also update the Bonjour parameters if a local
+ queue is upgraded from IPP to IPPS.
+
+CHANGES IN V1.0.33
+
+ - cups-browsed: Added NULL check (Bug #1106).
+
+CHANGES IN V1.0.32
+
+ - cups-browsed: Shared algorithm to generate local queues based on
+ browsed remote queue data between Bonjour and CUPS browsing, as the
+ simpler method used for CUPS browsing could overwrite local print
+ queues and had de-duplication problems, for example if the server
+ appears on two IPs in the network (connected by both ethernet and
+ WLAN).
+ - cups-browsed: CUPS broadcasting also broadcasted non-shared,
+ especially cups-browsed-generated printers. Switched to detection
+ of non-shared printers by the appropriate bit in the printer-type
+ bit field IPP attribute.
+ - cups-browsed: Made CUPS broadcasting work also without BrowseAllow
+ lines in cups-browsed.conf. In this case we accept all remote
+ printers (Ubuntu bug #1163764).
+ - README: Updated documentation for cups-browsed.
+ - Added more comments and examples to /etc/cups/cups-browsed.conf.
+ - cups-browsed: Added support for "...:<port>" extensions of
+ BrowsePoll addresses. Thanks to Tim Waugh from Red Hat (Ubuntu
+ bug 1159213).
+
+CHANGES IN V1.0.31
+
+ - cups-browsed: cups-browsed removed valid local queues pointing to
+ remote queues when cups-browsed did not shut down cleanly after
+ the previous session, leaving the user with missing local accessor
+ queues for some of the remote CUPS queues (Ubuntu bug #1131149).
+ - Fixed build system to allow parallel or multilib builds. Thanks to
+ Timo Gurr for the patch (Bug #1104).
+ - pdftopdf: Improved error output.
+ - pdftopdf: getRotation now handles unusual cases more graceful
+ (probably fixes Ubuntu Bug #1154318).
+ - Fixed build system to allow building without Avahi. In this case
+ a cups-browsed with only CUPS broadcasting/browsing will get
+ built. Thanks to Tim Waugh from Red Hat (Bug #1101, Bug #1102).
+
+CHANGES IN V1.0.30
+
+ - cups-browsed: Do not remove a generated local print queue when
+ it was made the system default printer (Ubuntu bug #1146407).
+ - texttopdf: Fixed corrupted pdf when a utf-8 title is given and
+ corresponding crash with 'prettyprint' (Ubuntu Bug #1137438).
+ - cups-browsed: Added CUPS Broadcasting for sharing local printers
+ to remote CUPS clients with CUPS 1.5.x and older. Thanks to Tim
+ Waugh from Red Hat.
+ - cups-browsed: Added sample config-file and build-time default
+ setting options. Thanks to Tim Waugh from Red Hat.
+ - cups-browsed: Added CUPS browsing and BrowsePoll functionality, to
+ be backwards compatible to CUPS 1.5.x and older servers. Thanks
+ to Tim Waugh from Red Hat.
+ - pdftopdf: Fixed incorrect evenDuplex page insertion (Bug #1088).
+ - pdftoopvp: Let it build with Poppler 0.22.x. Thanks to Koji Otani
+ from BBR Inc. (Bug #1089).
+
+CHANGES IN V1.0.29
+
+ - Fixed ./configure option "--with-rcdir=no". Thanks to Jiri
+ Popelka from Red Hat (Bug #1091).
+
+CHANGES IN V1.0.28
+
+ - cups-browsed: Do not create CUPS queues for shared local CUPS
+ printers.
+
+CHANGES IN V1.0.27
+
+ - cups-browsed: The daemon crashed if there is no local CUPS queue
+ at all. Fixed.
+
+CHANGES IN V1.0.26
+
+ - Some fixes in README and INSTALL.
+ - cups-browsed: Added daemon to browse the Bonjour broadcasts of
+ shared remote CUPS printers and automatically add local raw queues
+ pointing to them, to resemble the behavior of the former CUPS
+ broadcasting/browsing which was dropped in CUPS 1.6. Now remote
+ printers appear as local print queues as before, but with the
+ standardized Bonjour broadcasting.
+ - "make dist" got broken in 1.0.25. Fixed.
+
+CHANGES IN V1.0.25
+
+ - urftopdf: Newly added filter to convert the URF format which (at
+ least some) iOS apps send when printing via AirPrint (Bug #1076).
+ - pdftopdf: pdfautorotate functionality has been patched directly
+ into pdftopdf (Bug #1080).
+ - pdftopdf: "mirror" produced only empty pages (XObjects not there).
+ - pdftopdf: Fixed segfault on "page-ranges=1-2147483647" (from cups).
+ - pdftopdf: Fixed collate filler insertion.
+ - texttopdf: Fixed deficient string escaping (Bug #1071).
+ - pdftoopvp: Get correct byte order definition when building under
+ OpenBSD (Bug #1070).
+ - serial backend: Added check for sys/ioctl.h to configure.ac (Bug
+ #1069).
+ - pdftopdf: Made code building under OpenBSD (Bug #1068).
+ - pdftopdf: Don't expect too much C++11 support for now (Bug #1067).
+
+CHANGES IN V1.0.24
+
+ - pdftopdf now generates the necessary pdf comments to disable
+ duplicate number-up when pdftops is also applied (Bug #1063).
+ - pdftops: Added support for using Adobe Reader (acroread) in command
+ line mode for turning PDF to PostScript (Bug #1065).
+ - pdftopdf: Fix build on OpenBSD (Bug #1062).
+ - pdftops: Fix stripping of page management options from the pstops
+ command line which got already applied by pdftopdf. If the name
+ of the option to be removed is contained in the name of a option
+ in the command line (like "number-up" in "number-up-layout" or
+ "scaling" in "Natural-scaling"), this option gets stripped instead
+ of the correct option (Bug #1064).
+
+CHANGES IN V1.0.23
+
+ - Removed filter/pdftopdf.old
+ - Fixed the requires.private for cupsfilters lib
+
+CHANGES IN V1.0.22
+
+ - Added missing *.h files of filter/pdftopdf/ to source file list so
+ that "make dist" builds correct upstream tarballs.
+
+CHANGES IN V1.0.21
+
+ - bannertopdf: Page duplication routine fixed.
+ - bannertopdf: Fixed invalid output of a direct stream object.
+ - pdftopdf filter replaced by new QPDF-based filter from Tobias
+ Hoffmann's Google Summer of Code project. The former Poppler-based
+ pdftopdf duplicated a lot of Poppler's code. The old filter is
+ still in the package as pdftopdf.old with source code in
+ filter/pdftopdf.old. It will be removed in a later release.
+ - Added most recent contributors to AUTHORS and COPYING files.
+
+CHANGES IN V1.0.20
+
+ - pdftops: Added another workaround for Kyocera printers: Some
+ models get very slow on images which request interpolation,
+ so now we remove the image interpolation requests by additional
+ PostScript code only inserted for Kyocera printers (Ubuntu bug
+ #1026974).
+ - pdftops: The build system only configured the default renderer
+ (Ghostscript OR Poppler), not the other renderer, but as we support
+ switching on runtime both need to get configured.
+ - Improved portability of the package to non-Linux systems (Bug #1056).
+ - Made the Poppler-based filters pdftopdf and pdftoopvp build with
+ both Poppler 0.18.x and 0.20.x (Bug #1055).
+ - Let build system check for dlopen.
+
+CHANGES IN V1.0.19
+
+ - Fixes according to Coverity scan results (Bug #1054).
+ - Added distribution packaging instructions to INSTALL.
+ - Switched build system to autotools. This especially fixes several
+ build problems in Gentoo. Also build-tested with CUPS 1.6.0b1.
+ - Fixes for compatibility with clang/gcc-4.7.
+ - textonly: Filter did not work as a pipe with copies=1 (Bug #1032).
+ - texttopdf: Avoid trimming the results of FcFontSort(), as this may
+ miss some reasonable candidates under certain circumstances. BTW,
+ fix passing a non-pointer as a pointer to "result" (Debian bug
+ #670055),
+ - Corrected documentation. The option for the maximum image rendering
+ resolution in pdftops is "pdftops-max-image-resolution", not
+ "pdftops-max-image-resolution-default".
+
+CHANGES IN V1.0.18
+
+ - Modified "./configure" options related to the pdftops filter to
+ allow changing the defaults for the renderer being used by default
+ (Ghostscript or Poppler) and the maximum image rendering resolution
+ and to supply paths for both Ghostscript's gs and Poppler's pdftops.
+ - pdftops: Allow selection whether Ghostscript or Poppler is used
+ at runtime, setting the "pdftops-renderer" option to "gs" or
+ "pdftops".
+ - pdftops: Allow setting an upper limit for the image rendering
+ resolution, also at runtime, setting the option
+ "pdftops-max-image-resolution" to the desired limit in dpi.
+ "0" means no limit.
+ - pdftops: Fixed crash by wrong usage of sizeof() function when adding
+ "Collate" to the fifth command line argument for the "pstops" CUPS
+ filter call (Ubuntu bug #982675).
+ - pdftops: Removed newline from copies value when reading it from
+ the "%%PDFTOPDFNumCopies" entry of the incoming PDF file.
+ - pdftops: Silenced compiler warning about ignoring the return
+ value of the write() function.
+ - pdftops: Added a crash guard.
+ - pdftops: Start determining the printing resolution with
+ cupsRasterInterpretPPD(), this is the most reliable as often
+ the choice names of the "Resolution" option are marketing names
+ with higher numerical values than the actual resolution. Also
+ ignore error exit values of cupsRasterInterpretPPD() as the
+ function can error out after having found the resolution.
+ - pdftops: If printing resolution is determined by
+ cupsRasterInterpretPPD() do not stick on 100 dpi if the
+ resolution cannot be determined (Ubuntu bug #984082).
+
+CHANGES IN V1.0.17
+
+ - pdftopdf: Fixed segmentation fault when printing selected pages
+ ("page-ranges" option, Ubuntu bug #980673).
+
+CHANGES IN V1.0.16
+
+ - pdftopdf: Fixed segmentation faults when using N-up with certain PDF
+ files (Ubuntu bug #980673) and when calling pdftopdf manually without
+ specifyting a PPD file.
+
+CHANGES IN V1.0.15
+
+ - pdftops: Suppress image compression only for Brother printers as they
+ really need this measure to print at all. This accelerates printer-
+ internal job processing on most other printers (tested on HP and
+ Kyocera). Also suppress page compression on Kyocera printers, this
+ works around a bug in Kyocera's PostScript interpreters which makes
+ printing pages with images very slow (Ubuntu bug #977912).
+
+CHANGES IN V1.0.14
+
+ - pdftops: Determine printing resolution from the PPD file and supply
+ it on the Ghostscript or pdftops (Poppler) command line, so that
+ the renderer does the image rendering with a resolution matching the
+ printer's resolution. This avoids too slow processing of the jobs
+ by the printer's built-in PostScript interpreter. In addition
+ a default resolution of 300 dpi is used for PPDs without any hint
+ of the printer's resolution, as most PostScript lasers use multiples
+ of 300 dpi as resolution (Ubuntu bug #977912).
+
+CHANGES IN V1.0.13
+
+ - bannertopdf: Fix display of the job dates on the test page and on
+ banner pages (Ubuntu bug #975064).
+
+CHANGES IN V1.0.12
+
+ - Fixed crash of imagetopdf filter when it is called manually
+ without supplying a valid PPD file (Ubuntu bug #973564).
+
+CHANGES IN V1.0.11
+
+ - Actually install the Generic PDF printer PPD file.
+ - Really introduce a Generic PDF printer PPD file.
+
+CHANGES IN V1.0.10
+
+ - Added Generic PPD file for native PDF printers.
+ - Updated all code copied from Poppler to the current state of Poppler.
+ - Made Poppler-based PDF filters building with various versions of
+ Poppler.
+
+CHANGES IN V1.0.9
+
+ - Deactivated NIME conversion rules which are not used by the PDF-
+ based printing workflow.
+ - Cleaned up sample PPD file HP-Color_LaserJet_CM3530_MFP-PDF.ppd.
+ - imagetopdf: Added support for native PDF printers.
+ - imagetopdf, imagetoraster: Let image input "scale to fit"
+ by default. This makes photo printing via AirPrint work,
+ as the iOS devices send JPEG but do not allow setting options.
+
+CHANGES IN V1.0.8
+
+ - pdftops: Generally do not compress fonts and images, and
+ also do not do CCITT compression for bitmap glyphs to make
+ the PostScript output more compatible with buggy PostScript
+ interpreters. The output gets 30-50% longer but will work on
+ many more different printer models. Problems were also
+ discovered on HP and not only on Brother (Ubuntu bug
+ #960666).
+
+CHANGES IN V1.0.7
+
+ - pdftops: Added PostScript debug mode. For jobs sent with "-o psdebug"
+ the PostScript output by Ghostscript does not have compression of
+ pages and fonts, so that one can analyse the PostScript code,
+ especially in cases of incompatibilities and bugs of the built-in
+ PostScript interpreters of printers. Thanks to the Ghostscript
+ upstream developers for this hint.
+
+CHANGES IN V1.0.6
+
+ - texttopdf: Fixed minor miscalculation of /AvgWidth.
+ - texttopdf: Added support for direct file references in pdf.utf-8.
+ - pdftops: Added another workaround for a bug in Brother's PostScript
+ interpreter: Suppress CCITT compression for bitmap glyphs and
+ images on Brother printers (Ubuntu bug #955553).
+ - texttopdf: Fixed typo in pdf font descriptor dictionary keys.
+ - Fixed ColorDevice definition in cupsfilters.drv for HP DesignJet
+ printers.
+ - Put ModelNumber entries in cupsfilters.drv at the right place to
+ get correct "*cupsModelNumber:" entries in the PPDs for the HP
+ DesignJet printers.
+ - rastertopclx: Code of JCL options did not get inserted into the JCL
+ header.
+ - parallel backend: Use the same way as CUPS does to prevent an
+ infinite loop on side channel errors (CUPS STR #4044).
+ - pdftopdf: Added support for native PDF printers, add JCL (PJL)
+ options and send page_log entries only if the PDF has the
+ "*JCLToPDFInterpreter:" keyword.
+ - Updated README.txt for the new native PDF printer support.
+ - Added a sample PPD file for a native PDF printer,
+ HP-Color_LaserJet_CM3530_MFP-PDF.ppd.
+ - texttopdf: A lot of internal rework; also split up into more files
+ - texttopdf: Fixed many bugs on the way
+ - texttopdf: Added support for CFF-flavoured OTFs; for these
+ subsetting is not yet implemented, full embedding is done instead
+ - texttopdf: Adapted and improved fontconfig font selection
+ - Make sure that "make clean" and "make distclean" also work if
+ Makedefs does not exist (Debian bug #663564).
+
+CHANGES IN V1.0.5
+
+ - pdftops: Added insertion of workaround PostScript code for printers
+ with bugs in their PS interpreters (Ubuntu bugs #950713, #951627).
+ - parallel backend: Break infinite loop (Ubuntu bug #936647).
+ - texttopdf: Complete the implementation of fontconfig-based font
+ selection (Debian bug #663070).
+
+CHANGES IN V1.0.4
+
+ - texttopdf: Fall back to altermative fonts via fontconfig if the
+ FreeMono TrueType fonts are not installed (Debian bugs #495598
+ and #662660).
+ - bannertopdf: Fix off-by-one error in page duplication
+ - bannertopdf: Put indirect references to streams into the page's
+ contents
+ - bannertopdf: Let byte offsets for the Xref table of the PDF output
+ being determined correctly also when the output goes to stdout
+ (Ubuntu bug #939735).
+ - bannertopdf: Output multiple copies of the test page if duplex
+ and/or N-up is chosen, to let the test page appear on all possible
+ positions of the sheet (Ubuntu bug #939530).
+
+CHANGES IN V1.0.3
+
+ - bannertopdf: Draw the frame to mark the non-printable borders 1pt
+ smaller all around to assure that it is always visible, like it was
+ done in bannertops.
+ - bannertopdf: Scale the page to fit onto the desired output page.
+ - bannertopdf: Get and output the correct media limits.
+
+CHANGES IN V1.0.2
+
+ - bannertopdf: Fixed crash caused by wrong Poppler API use.
+ - bannertopdf: Info text on test page came out in gray and not in
+ black.
+
+CHANGES IN V1.0.1
+
+ - Added the textonly filter and its PPD file, a driver for text-only
+ printers.
+ - Install the pdftoijs sample PPD file
+ HP-PhotoSmart_Pro_B8300-hpijs-pdftoijs.ppd
+ - Added cupsfilters.drv, centralized ppdc-based PPD generator for the
+ printer driver filters in this package. Current printers supported
+ are several HP DesignJet large format inkjet printers.
+ - Fixed "make uninstall". Now everything of this package gets removed.
+ - Added wrapper scripts texttops and imagetops for backward
+ compatibility to third-party PPD files or custom configurations
+ which refer to these filters explicitly (Debian bug #658258).
+
+CHANGES IN V1.0
+
+ - Built the pdftops filter based on Ghostscript by default, as
+ Ghostscript is better optimized for print output (Ubuntu bug
+ #926068).
+ - If the pdftops filter is built for using Poppler, let Poppler not
+ emit PostScript level 3, as this causes problems with some HP
+ printers (Ubuntu bug #277404, Freedesktop (Poppler) bug #19640).
+ - bannertopdf needs to be linked with C++ (bug #995)
+ - Added test.sh script for testing texttopdf
+ - Added original documentation of the PDF filters to README.txt
+ - Install C header files and the static library
+ - General clean-up of "make install" targets in Makefiles
+ - Raised MIME conversion cost factor of pdftoraster from 66 to 100 to
+ give priority to the gstoraster filter from Ghostscript, as this
+ filter supports ICC-profile-based color management.
+ - Documentation updated because libijs, liblcms, freetype, and
+ fontconfig are needed to build this package
+
+CHANGES IN V1.0b1
+
+ - Removed the bannertops, imagetops, and texttops filters, they are
+ not needed any more in the PDF-based printing workflow
+ - Added support for liblcms2
+ - Named the package "OpenPrinting CUPS Filters"

+ OpenPrinting: http://sourceforge.jp/projects/opfc/ and
+ http://www.openprinting.org/download/printing/pdf-printing/
+ - Initial packaging of files that are no longer included in CUPS 1.6
+ from CUPS upstream (http://www.cups.org/)

+# CHANGES - OpenPrinting CUPS Filters v2.0b1 - 2022-11-14
+
+## CHANGES IN V2.0b1 (TBA)
+
+### libcupsfilters
+
+- Introduced the filter functions concept converting filter
+ executables into library functions with common call scheme, moving
+ their core functionality into libcupsfilters and allowing easier use
+ by Printer Applications. Common data about the printer and the job
+ are supplied via a data structure, which is the same for each filter
+ in a chain of filters. The data structure can be extended via named
+ extensions.
+
+- Converted nearly all filters to filter functions, only exceptions
+ are rastertoescpx, rastertopclx, commandtoescpx, commandtopclx, and
+ foomatic-rip. The latter is deeply involved with Foomatic PPDs and
+ the others are legacy printer drivers. Filter functions which
+ output PostScript are implemented in libppd.
+
+- Converted CUPS' rastertopwg filter into the cfFilterRasterToPWG()
+ filter function.
+
+- Created new cfFilterPWGToRaster() filter function primarily to print
+ raster input (PWG Raster, Apple Raster, images) to CUPS Raster
+ drivers in driver-retro-fitting Printer Applications.
+
+- Converted all filter functions to completely work without PPD files,
+ using only printer and job IPP attributes and an option list for
+ options not mappable to IPP attributes. For some filter functions
+ there are also wrappers for a more comprehensive PPD file support in
+ libppd.
+
+- Added concept of callback functions for logging, for the filter
+ functions not spitting their log to stderr.
+
+- Added concept of callback functions for telling that a job is
+ cancelled so that filter functions can return early. This change is
+ to get more flexibility and especially to support the
+ papplJobIsCanceled() of PAPPL.
+
+- Added new streaming mode triggered by the boolean
+ "filter-streaming-mode" option. In this mode a filter (function) is
+ supposed to avoid everything which prevents the job data from
+ streaming, as loading the whole job (or good part of it) into a
+ temporary file or into memory, interpreting PDF, pre-checking input
+ file type or zero-page jobs, ... This is mainly to be used by
+ Printer Applications when they do raster printing in streaming mode,
+ to run with lowest resources possible. Currently
+ cfFilterGhostscript() and cfFilterPDFToPDF() got a streaming
+ mode. In streaming mode PostScript (not PDF) is assumed as input and
+ no zero-page-job check is done, and all QPDF processing (page
+ management, page size adjustment, ...) is skipped and only JCL
+ according to the PPD added.
+
+- Added raster-only PDF and PCLm output support to the ghostscript()
+ filter function. Note that PCLm does not support back side
+ orientation for duplex.
+
+- cfFilterPDFToPDF(): Introduced new "input-page-ranges" attribute
+ (Issue #365, Pull request #444, #445).
+
+- Added cfFilterChain() filter function to run several filter
+ functions in a chain.
+
+- Added filterPOpen() and filterPClose() functions which similar to
+ popen() and pclose() create a file descriptor which either takes
+ data to feed into a filter function or provides data coming out of a
+ filter function.
+
+- Added new cfFilterExternal() filter function which calls an external
+ CUPS filter (or backend) executable specified in the parameters, for
+ example a legacy or proprietary printer driver which cannot be
+ converted into a filter function. Backends can be run both for job
+ execution or in their discovery mode. The environment in which the
+ external executable is running is resembling CUPS as best as
+ possible.
+
+- Added support for the back and side channels which CUPS uses for
+ additional communication between the filters and the backend into
+ the filter function infrastructure. Now filter functions can use
+ these channels and also CUPS filters or backends called via the
+ cfFilterExternal() function. Printer Applications can easily create
+ the needed pipes via the new function cfFilterOpenBackAndSidePipes()
+ and close them via cfFilterCloseBackAndSidePipes() and filter
+ functions used as classic CUPS filters get the appropriate file
+ descriptors supplied by ihe ppdFilterCUPSWrapper() function of
+ libppd.
+
+- Added the cfFilterUniversal() filter function which allows a single
+ CUPS filter executable which auto-creates chains of filter function
+ calls to convert any input data format into any other output data
+ format. So CUPS can call a single filter for any conversion, taking
+ up less resources. Thanks to Pranshu Kharkwal for this excellent
+ GSoC project (Pull request #421).
+
+- Added functions to read out IPP attributes from the job and check
+ them against the IPP attributes (capabilities) of the printer:
+ cfIPPAttrEnumValForPrinter(), cfIPPAttrIntValForPrinter(),
+ cfIPPAttrResolutionForPrinter()
+
+- Added functions cfGenerateSizes() and cfGetPageDimensions() to match
+ input page sizes with the page sizes available on the printer
+ according to printer IPP attributes.
+
+- Moved IEEE1284-device-ID-related functions into the public API of
+ libcupsfilters, also made the internal functions public and renamed
+ them all to cfIEEE1284...(), moved test1284 to cupsfilters/.
+
+- Extended cfIEEE1284NormalizeMakeAndModel() to a universal function
+ to clean up and normalize make/model strings (also device IDs) to
+ get human-readable, machine-readable, or easily sortable make/model
+ strings. Also allow supplying a regular expression to extract driver
+ information when the input string is a PPD's *NickName.
+
+- When calling filters without having printer attributes, improved
+ understanding of color mode options/attributes. Options
+ "output-mode", "OutputMode", "print-color-mode", and choices "auto",
+ "color", "auto-monochrome", "process-monochrome", and "bi-level" are
+ supported now and default color mode is RGB 8-bit color and not
+ 1-bit monochrome.
+
+- When parsing IPP attributes/options map the color spaces the same
+ way as in the PPD generator (Issue #326, Pull request #327).
+
+- Added new oneBitToGrayLine() API function which converts a line of
+ 1-bit monochrome pixels into 8-bit grayscale format
+ (cupsfilters/bitmap.[ch]).
+
+- Removed support for asymmetric image resolutions ("ppi=XXXxYYY") in
+ cfFilterImageToPDF() and cfFilterImageToRaster() as CUPS does not
+ support this (Issue #347, Pull request #361, OpenPrinting CUPS issue
+ #115).
+
+- Removed now obsolete apply_filters() API function to call a chain of
+ external CUPS filter executables, as we have filter functions now
+ and even can call one or another filter executable (or even backend)
+ via cfFilterExternal().
+
+- Build system, README: Require CUPS 2.2.2+ and QPDF 10.3.2+. Removed
+ now unneeded ./configure switches for PCLm support in QPDF and for
+ use of the urftopdf filter for old CUPS versions.
+
+- Renamed function/data type/constant names to get a consistent API:
+ Functions start with "cf" and the name is in camel-case, data types
+ start with "cf_" and are all-lowercase with "_" separators,
+ constants start with "CF_" and are all-uppercase, also with "_"
+ separators.
+
+- Bumped soname to 2, as we have a new API now.
+
+- Build system: Remove '-D_PPD_DEPRECATED=""' from the compiling
+ command lines of the source files which use libcups. The flag is not
+ supported any more for longer times already and all the PPD-related
+ functions deprecated by CUPS have moved into libppd now.
+
+- Older versions of libcups (< 2.3.1) had the enum name for
+ fold-accordion finishings mistyped. Added a workaround.
+
+- Added support for Sharp-proprietary "ARDuplex" PPD option name for
+ double-sided printing.
+
+- Build system: Add files in gitignore that are generated by
+ "autogen.sh", "configure", and "make" (Pull request #336).
+
+- Fixed possible crash bug in oneBitLine() function.
+
+- In ghostscript() pass on LD_LIBRARY_PATH to Ghostscript
+
+
+### libppd
+
+- Added the new libppd library overtaking all the PPD handling
+ functions from libcups, CUPS' ppdc utility (PPD compiler using *.drv
+ files), and the PPD file collection handling functionality from
+ cups-driverd, as they are deprecated there and will probably get
+ removed with the next CUPS version. This form of conservation is
+ mainly intended for converting classic printer drivers which use
+ PPDs into Printer Applications without completely rewriting them.
+
+- Added functions ppdLoadAttributes(), ppdFilterLoadPPD(),
+ ppdFilterLoadPPDFile(), ppdFilterFreePPD(), and
+ ppdFilterFreePPDFile() to convert all PPD file options and settings
+ relevant for the filter functions in libcupsfilters into printer IPP
+ attributes and options. Also create a named ("libppd") extension in
+ the filter data structure, for filter functions explicitly
+ supporting PPD files.
+
+- Added ppdFilterCUPSWrapper() convenience function to easily create a
+ classic CUPS filter from a filter function.
+
+- Converted the ...tops CUPS filters into the filter functions
+ ppdFilterPDFToPS(), and ppdFilterRasterToPS(). As PostScript as
+ print output format is as deprecated as PPD gfiles and all
+ PostScript printers use PPD files, we move PostScript output
+ generation to libppd, too.
+
+- Converted CUPS' pstops filter into the ppdFilterPSToPS() filter
+ functions.
+
+- Introduced ppdFilterImageToPS() filter function for Printer
+ Applications to print on PostScript printers. It is used to print
+ images (IPP standard requires at least JPEG to be accepted) without
+ need of a PDF renderer (cfFilterImageToPDF -> cfFilterPDFToPS) and
+ without need to convert to Raster (cfFilterImageToRaster ->
+ cfFilterRasterToPS).
+
+- Created wrappers to add PPD-defined JCL code to jobs for native PDF
+ printers, ppdFilterImageToPDF() and ppdFilterPDFToPDF() filter
+ functions with the underlying ppdFilterEmitJCL() function.
+
+- Created ppdFilterUniversal() wrapper function for
+ cfFilterUniversal() to add PPD file support, especially for PPD
+ files which define driver filters.
+
+- ppdFilterExternalCUPS() wrapper function for cfFilterExternal() to
+ add PPD file support.
+
+- Auto-pre-fill the presets with most suitable options from the PPD
+ files with new ppdCacheAssignPresets() function (Only if not filled
+ via "APPrinterPreset" in the PPD). This way we can use the IPP
+ options print-color-mode, print-quality, and print-content-optimize
+ in a PPD/CUPS-driver-retro-fitting Printer Application with most
+ PPDs.
+
+- In ppdCacheCreateWithPPD() also support presets for
+ print-ontent-optimize, not only for print-color-mode and
+ print-quality
+
+- In the ppdCacheGetPageSize() function do not only check the fit of
+ the margins with the page size matching the job's page size (like
+ "A4") but also the margins of the variants (like "A4.Borderless"),
+ even if the variant's size dimensions differ from the base size (and
+ the physical paper size), for example for overspray in borderless
+ printing mode (HPLIP does this). Also select a borderless variant
+ only if the job requests borderless (all margins zero).
+
+- Move the functions ppdPwgUnppdizeName(), ppdPwgPpdizeName(), and
+ ppdPwgPpdizeResolution() into the public API.
+
+- In the ppdPwgUnppdizeName() allow to supply NULL as the list of
+ characters to replace by dashes. Then all non-alpha-numeric
+ characters get replaced, to result in IPP-conforming keyword
+ strings.
+
+- In the ppdPwgUnppdizeName() function support negative numbers
+
+- ppdFilterPSToPS(): Introduced new "input-page-ranges" attribute
+ (Issue #365, Pull request #444, #445).
+
+- Changed "ColorModel" option in the PPDs from the PPD generator to
+ mirror the print-color-mode IPP attribute instead of providing all
+ color space/depth combos for manual selection. Color space and depth
+ are now auto-selected by the urf-supported and
+ pwg-raster-document-type-supported printer IPP attributes and the
+ settings of print-color-mode and print-quality. This is now
+ implemented in the ghostscript() filter function both for use of the
+ auto-generated PPD file for driverless iPP printers and use without
+ PPD, based on IPP attributes. For this the new library functions
+ cupsRasterPrepareHeader() to create a header for Raster output and
+ cupsRasterSetColorSpace() to auto-select color space and depth were
+ created.
+
+- Clean-up of human-readable string handling in the PPD generator.
+
+- Removed support for asymmetric image resolutions ("ppi=XXXxYYY") in
+ cfFilterImageToPS() as CUPS does not support this (Issue #347, Pull
+ request #361, OpenPrinting CUPS issue #115).
+
+- Removed versioning.h and the macros defined in this file (Issue
+ #334).
+
+- Removed ppdCreateFromIPPCUPS(), we have a better one in
+ libcupsfilters. Also removed corresponding test in testppd.
+
+- Build system, README: Require CUPS 2.2.2+ and QPDF 10.3.2+. Removed
+ now unneeded ./configure switches for PCLm support in QPDF and for
+ use of the urftopdf filter for old CUPS versions.
+
+- Build system: Remove '-D_PPD_DEPRECATED=""' from the compiling
+ command lines of the source files which use libcups. The flag is not
+ supported any more for longer times already and all the PPD-related
+ functions deprecated by CUPS have moved into libppd now.
+
+- Older versions of libcups (< 2.3.1) had the enum name for
+ fold-accordion finishings mistyped. Added a workaround.
+
+- Added support for Sharp-proprietary "ARDuplex" PPD option name for
+ double-sided printing.
+
+- Build system: Add files in gitignore that are generated by
+ "autogen.sh", "configure", and "make" (Pull request #336).
+
+- Fixed PPD memory leak caused by "emulators" field not freed
+ (OpenPrinting CUPS issue #124). - Make "True" in boolean options
+ case-insensitive (OpenPrinting CUPS pull request #106).
+
+
+### cups-filters
+
+- Converted nearly all filters to filter functions, only exceptions
+ are rastertoescpx, rastertopclx, commandtoescpx, commandtopclx, and
+ foomatic-rip. The latter is deeply involved with Foomatic PPDs and
+ the others are legacy printer drivers.
+
+- Replaced all the filters converted to filter functions by a simple
+ wrapper executable using ppdFilterCUPSWrapper() for backward
+ compatibility with CUPS 2.x.
+
+- Added new streaming mode triggered by the boolean
+ "filter-streaming-mode" option. In this mode a filter (function) is
+ supposed to avoid everything which prevents the job data from
+ streaming, as loading the whole job (or good part of it) into a
+ temporary file or into memory, interpreting PDF, pre-checking input
+ file type or zero-page jobs, ... This is mainly to be used by
+ Printer Applications when they do raster printing in streaming mode,
+ to run with lowest resources possible. Currently foomatic-rip,
+ ghostscript, and pdftopdf got a streaming mode. For the former two
+ PostScript (not PDF) is assumed as input and no zero-page-job check
+ is done, in the latter all QPDF processing (page management, page
+ size adjustment, ...) is skipped and only JCL according to the PPD
+ added.
+
+- The CUPS filter imagetops uses the cfFilterImageToPS() filter
+ function now.
+
+- driverless, driverless-fax, Added IPP Fax Out support. Now printer
+ setup tools list an additional fax "driver". A fax queue is created
+ by selecting this driver. Jobs have to be sent with "-o phone=12345"
+ to supply the destination phone number (Pull request #280, #293,
+ #296, #302, #304, #305, #306, #309, Issue #298, #308).
+
+- sys5ippprinter, cups-browsed: Removed sys5ippprinter, as CUPS does
+ not support System V interface scripts any more. This first approach
+ of PPD-less printing was also not actually made use of.
+
+- urftopdf: Removed as we require CUPS 2.2.2+ now which supports Apple
+ Raster by itself.
+
+- Build system, README: Require CUPS 2.2.2+ and QPDF 10.3.2+. Removed
+ now unneeded ./configure switches for PCLm support in QPDF and for
+ use of the urftopdf filter for old CUPS versions.
+
+- Sample PPDs: Renamed source directory from "ppd/" to "ppdfiles/"
+
+- Build system: Added missing library dependencies to the filters to
+ make parallel builds work (Issue #319).
+
+- Build system: Remove '-D_PPD_DEPRECATED=""' from the compiling
+ command lines of the source files which use libcups. The flag is not
+ supported any more for longer times already and all the PPD-related
+ functions deprecated by CUPS have moved into libppd now.
+
+- Build system: Add files in gitignore that are generated by
+ "autogen.sh", "configure", and "make" (Pull request #336).
+
+
+### braille-printer-app
+
+- textbrftoindex: Fix control character filtering (Pull
+ request #409)
+
+- Build system: Remove '-D_PPD_DEPRECATED=""' from the
+ compiling command lines of the source files which use
+ libcups. The flag is not supported any more for longer times
+ already and all the PPD-related functions deprecated by CUPS
+ have moved into libppd now.

-NEWS - OpenPrinting CUPS Filters v1.27.5 - 2020-06-05
------------------------------------------------------
-
-CHANGES IN V2.0.0
-
- - libcupsfilters: Added new API function cfFilterLoadPPD() and
- cfFilterFreePPD() for easy setup of filter function (chain)
- calls. Call cfFilterLoadPPD() when setting up the filter
- data structure before calling the filter functions and call
- cfFilterFreePPD() when done.
- - libcupsfilters: Renamed function/data type/constant names to
- get a consistent API: Functions start with "cf" and the name
- is in camel-case, data types start with "cf_" and are
- all-lowercase with "_" separators, constants start with
- "CF_" and are all-uppercase, also with "_" separators.
- - libcupsfilters: Bumped soname to 2, as we have a new API now
- - pdftopdf, pstops: Introduced new "input-page-ranges"
- attribute (Issue #365, Pull request #444, #445).
- - Braille: In vectortopdf check inkscape version to call
- inkscape with the correct command line (Issue #315, Pull
- request #443).
- - cups-browsed: Naming of local queues is matched to CUPS'
- current naming of temporary queues (no leading or trailing
- underscores), to avoid duplicates in print dialogs which
- support CUPS' temporary queues.
- - libcupsfilters: Removed now obsolete apply_filters() API
- function to call a chain of external CUPS filter
- executables, as we have filter functions now and even can
- call one or another filter executable (or even backend) via
- filterExternalCUPS().
- - cups-browsed, implicitclass: Let the implicitclass backend
- use filter functions instead of calling filter executables.
- - libcupsfilters, universal: Added the universal() filter
- function which allows a single CUPS filter executable which
- auto-creates chains of filter function calls to convert any
- input data format into any other output data format.So CUPS
- can call a single filter for any conversion, taking up less
- resources. Thanks to Pranshu Kharkwal for this excellent
- GSoC project (Pull request #421).
- - Build system, README: Require CUPS 2.2.2+ and QPDF 10.3.2+.
- Removed now unneeded ./configure switches for PCLm support
- in QPDF and for use of the urftopdf filter for old CUPS
- versions.
- - urftopdf: Removed as we require CUPS 2.2.2+ now which
- supports Apple Raster nby itself.
- - libppd: Ported CUPS' PPD compiler into libppd. Now the
- functions for PPD file collections also take driver
- information files (*.drv) into account, allowing easy
- retro-fit of ALL CUPS drivers. In addition, the API of CUPS'
- PPD compiler is available (ppd/ppdc.h) and everything stays
- available when CUPS drops PPD support.
- - libcupsfilters: Make cupsRasterParseIPPOptions() work
- correctly together with PPDs, by not parsing options
- which are in the printer's PPD and using
- ppdRasterInterpretPPD() when set_defaults = 1 is set.
- Without PPD the function behaves as before.
- - libcupsfilters: Let the ieee1284NormalizeMakeAndModel()
- function Clean up "Kodak" manufacturer name, as it is
- sometimes reported as "Eastman Kodak Company".
- - libcupsfilters, texttotext: Moved core functionality of
- texttotext into the texttotext() filter function (Pull
- request #425).
- - libcupsfilters: Let colord_get_profile_for_device_id() not
- return empty file name, to avoid error messages in CUPS
- error_log.
- - foomatic-rip: Debug message was wrongly sent to stdout and
- not to log (Issue #422).
- - libcupsfilters: In ghostscript() pass on LD_LIBRARY_PATH to
- Ghostscript
- - libcupsfilters: In color-management-related functions use
- the log function instead of logging right to stderr.
- - libcupsfilters: In ieee1284NormalizeMakeAndModel() extract
- driver info with regular expression.
- - libcupsfilters: Support print-rendering-intent IPP attribute
- in ghostscript(), mupdftoraster(), and pdftoraster() filter
- functions.
- - libcupsfilters, mupdftoraster: Moved core functionality of
- mupdftoraster into the mupdftoraster() filter function (Pull
- request #412).
- - textbrftoindex: Fix control character filtering (Pull
- request #409)
- - libcupsfilters, bannertopdf: Moved core functionality of
- bannertopdf into the bannertopdf() filter function (Pull
- request #407).
- - libcupsfilters, texttopdf: Moved core functionality of
- texttopdf into the texttopdf() filter function (Pull request
- #404).
- - libcupsfilters: The filterExternalCUPS() function. now
- supports also to run CUPS backends in discovery mode
- (without command line arguments and without input stream,
- list of discovered printers in output stream).
- - libcupsfilters: Added support for the back and side channels
- which CUPS uses for additional communication between the
- filters and the backend into the filter function
- infrastructure. Now filter functions can use these channels
- and also CUPS filters or backends called via the
- filterExternalCUPS() function. Printer Applications can
- easily create the needed pipes via the new function
- filterOpenBackAndSidePipes() and clode them via
- filterCloseBackAndSidePipes() and filter functions used as
- classic CUPS filters get the appropriate file descriptors
- supplied by ihe filterCUPSWrapper() function.
- - libcupsfilters: Added raster-only PDF and PCLm output
- support to the ghostscript() filter function. Note that
- these are experimental and not yet suitable for using in
- print filter chains, as they require a seekable output file
- and PCLm does not support back side orientation for duples.
- - libcupsfilters, foomatic-rip: Added new streaming mode
- triggered by the boolean "filter-streaming-mode" option. In
- this mode a filter (function) is supposed to avoid
- everything which prevents the job data from streaming, as
- loading the whole job (or good part of it) into a temporary
- file or into memory, interpreting PDF, pre-checking input
- file type or zero-page jobs, ... This is mainly to be used
- by Printer Applications when they do raster printing in
- streaming mode, to run with lowest resources possible.
- Currently foomatic-rip, ghostscript(), and pdftopdf() got a
- streaming mode. For the former two PostScript (not PDF) is
- assumed as input and no zero-page-job check is done, in the
- latter all QPDF processing (page management, page size
- adjustment, ...) is skipped and only JCL according to the
- PPD added.
- - Sample PPDs: Add borderless page size definitions to Generic
- PDF Printer, HP Color LaserJet CM3530 MFP PDF, and Ricoh PDF
- Printer PPD files.
- - Sample PPDs: From the PDF PPD files removed the unneeded
- "*cupsFilters2: ..." line. For CUPS it does not make any
- difference and the PPD-retro-fitting Printer Applications do
- not accept the PPDs with it.
- - libppd: In ppdCacheCreateWithPPD() also support presets for
- print-ontent-optimize, not only for print-color-mode and
- print-quality
- - libppd: Auto-pre-fill the presets with most suitable options
- from the PPD files with new ppdCacheAssignPresets() function
- (Only if not filled via "APPrinterPreset" in the PPD). This
- way we can use the IPP options print-color-mode,
- print-quality, and print-content-optimize in a
- PPD/CUPS-driver-retro-fitting Printer Application with most
- PPDs.
- - libppd: In the ppdCacheGetPageSize() function do not only
- check the fit of the margins with the page size matching the
- job's page size (like "A4") but also the margins of the
- variants (like "A4.Borderless"), even if the variant's size
- dimensions differ from the base size (and the physical paper
- size), for example for overspray in borderless printing mode
- (HPLIP does this). Also select a borderless variant only if
- the job requests borderless (all margins zero).
- - libcupsfilters: Fixed pdftopdf() filter function to
- correctly support page ranges without upper limit, like
- "10-" (Pull request #399).
- - libcupsfilters, pwgtoraster: Created new pwgtoraster()
- filter function primarily to print raster input (PWG Raster,
- Apple Raster, images) to CUPS Raster drivers in
- driver-retro-fitting Printer Applications.
- - libcupsfilters: Added new oneBitToGrayLine() API function
- which converts a line of 1-bit monochrome pixels into 8-bit
- grayscale format (cupsfilters/bitmap.[ch]).
- - libcupsfilters: Fixed possible crash bug in oneBitLine()
- function.
- - libcupsfilters, rastertopwg: Converted CUPS' rastertopwg
- filter into the rastertopwg() filter function.
- - libfontembed: Removed unneeded fontembed/main.c and ttfread
- executable (Issue #386).
- - texttotext: Made the filter also work when instead of PPDs
- and CUPS options printer and job IPP attributes are used
- (Pull request #385).
- - libcupsfilters: Made ghostscript() filter function also work
- when instead of PPDs and CUPS options printer and job IPP
- attributes are used (Pull request #383).
- - libcupsfilters, pdftoraster: Moved core functionality of
- pdftoraster into the pdftoraster() filter function (Pull
- request #381, #382).
- - cups-browsed: Make NotifLeaseDuration configurable and renew
- after half the lease duration not 60 sec before end. The
- early renewal improves reliability on busy systems a
- lot. For easier development and debugging short durations
- from 300 sec on can get selected (Pull request #378).
- - libcupsfilters: Removed duplicate code in the
- apply_filters() function.
- - libcupsfilters: Added new filterExternalCUPS() filter
- function which calls an external CUPS filter executable
- specified in the parameters, for example a legacy or
- proprietary printer driver which cannot be converted into a
- filter function.
- - driverless: If there are no driverless IPP printers
- available let "driverless" terminate with exit code 0 and
- not 1, to follow CUPS' standard of backends in discovery
- mode terminating with 0 if there are no appropriate printers
- found (Issue #375).
- - foomatic-rip: The fixes for zero-page-job handling (Pull
- request #209) broke PostScript streaming support. Changed
- method to check whether a PostScript input file is non-empty
- to only need to read and buffer the input up to the first
- page.
- - libcupsfilters: Changed "ColorModel" option in the PPDs from
- the PPD generator to mirror the print-color-mode IPP
- attribute instead of providing all color space/depth combos
- for manual selection. Color space and depth are now
- auto-selected by the urf-supported and
- pwg-raster-document-type-supported printer IPP attributes
- and the settings of print-color-mode and print-quality.
- This is now implemented in the ghostscript() filter function
- both for use of the auto-generated PPD file for driverless
- iPP printers and use without PPD, based on IPP attributes.
- For this the new library functions cupsRasterPrepareHeader()
- to create a header for Raster output and
- cupsRasterSetColorSpace() to auto-select color space and
- depth were created.
- - libcupsfilters: In the ghostscript() filter function fixed
- Ghostscript command line for counting pages as it took too
- long on PDFs from evince when printing DjVu files (Issue
- #354, Pull request #371, Ubuntu bug #1920730).
- - cups-browsed: Renamed ldap_connect() due to conflict in
- new openldap (Issue #367, Pull request #370).
- - libcupsfilters: Clean-up of human-readable string handling
- in the PPD generator.
- - libcupsfilters: Function name clean-up for the PPD
- generator.
- - libppd: Removed ppdCreateFromIPPCUPS(), we have a better one
- in libcupsfilters. Also removed corresponding test in
- testppd.
- - pdftoraster: Free color data after processing of each page
- (Pull request #363).
- - imagetopdf, imagetops, imagetoraster: Removed support for
- asymmetric image resolutions ("ppi=XXXxYYY") as CUPS does
- not support this (Issue #347, Pull request #361,
- OpenPrinting CUPS issue #115).
- - cups-browsed: Added multi-threaded operation, the Avahi
- resolver callback (which examines the remote printer,
- registers it, checks whether we want a local queue for it,
- adds it to a cluster, ...) and the creation/modification of
- a local CUPS queue is now done in separate threads, so that
- these processes can get executed in parallel to keep the
- local queues up-to-date more timely and to not overload the
- system's resources. Thanks a lot to Mohit Mohan who did
- this work as Google Summer of Code 2020 project
- (https://github.com/mohitmo/GSoC-2020-Documentation).
- - cups-browsed: Always save "...-default" option entries
- from printers.conf, regardless of presence or absense
- of PPD file (Pull request #359).
- - cups-browsed: Start after network-online.target (Pull
- request #360).
- - texttopdf: Set default margins when no PPD file is used
- (Pull request #356).
- - libppd: Fixed PPD memory leak caused by "emulators" field
- not freed (OpenPrinting CUPS issue #124).
- - libcupsfilters: Made check whether the driverless PPD to
- generate should be a fax out PPD more reliable (Issue #343).
- - foomatic-rip: Options in the 5th command line argument of
- the CUPS filter command line are separated only by white
- space and not by comma, also make sure that an option "none"
- is not considered a custom page size (Issue #348).
- - libppd: Make "True" in boolean options case-insensitive
- (OpenPrinting CUPS pull request #106).
- - implicitclass: Raise timeout for cups-browsed's answer from
- 20s to 60s (Pull request #346).
- - libppd: In the ppdPwgUnppdizeName() function support
- negative numbers
- - libcupsfilters: When normalizing printer model name replace
- '+' by "plus"
- - libcupsfilters, libppd: In the PPD generator really give
- priority to Apple Raster against PDF.
- - Build system: Add files in gitignore that are generated by
- "autogen.sh", "configure", and "make" (Pull request #336).
- - implicitclass: Added "#include <signal.h>" (Issue #335).
- - libppd: Removed versioning.h and the macros defined in this
- file (Issue #334).
- - driverless: Removed the support quality check from Pull
- request #235 as it takes significant time for each printer
- being listed, making cups-driverd (`lpinfo -m`) timing out
- when there are many printers (OpenPrinting CUPS issue #65).
- - libcupsfilters: Let the filter functions not load the PPD
- and not mark options in the PPD files to make them better
- usable with Printer Applications and to avoid race
- conditions in filter chains. To keep the behavior of CUPS
- filters, changed the filterCUPSWrapper() function
- appropriately.
- - libcupsfilters, libppd: In the PPD generators give priority
- to Apple Raster against PDF (Issue #331).
- - libcupsfilters: In the cupsRasterParseIPPOptions() map the
- color spaces the same way as in the PPD generator (Issue
- #326, Pull request #327).
- - libcupsfilters, libppd: In generated PPDs add a grayscale
- mode if there are only color printing modes (from
- OpenPrinting CUPS).
- - libcupsfilters, libppd: In generated PPDs add an "OutputBin"
- option also if it has only one choice (OpenPrinting CUPS
- pull request #18).
- - libcupsfilters, libppd: Generated PPDs could have an
- "Unknown" default InputSlot (OpenPrinting CUPS issue #44).
- - cups-browsed: Removed unneeded IPP attribute additions
- preventing the created local queues from preserving a
- location or description the user assigns to them (Issue
- #323).
- - cups-browsed: Removed all calls of the resolve_uri() function
- of libcupsfilters, as these are not actually needed and in case
- the supplied DNS-SD-based URI is not resolvable, the function
- gets stuck for ~5 seconds.
- - libcupsfilters: Added the possibility to define a callback
- function to tell the filter function when the job got
- canceled. Before, a pointer to an integer was used. This
- change is to get more flexibility and especially to support
- the papplJobIsCanceled() of PAPPL.
- - Build system: Added missing library dependencies to the
- filters to make parallel builds work (Issue #319).
- - libppd, libcupsfilters, bannertopdf, texttopdf: Added
- support for Sharp-proprietary "ARDuplex" PPD option name for
- double-sided printing.
- - libppd: Move the functions ppdPwgUnppdizeName(),
- ppdPwgPpdizeName(), and ppdPwgPpdizeResolution() into the
- public API.
- - libppd: In the ppdPwgUnppdizeName() allow to supply NULL as
- the list of characters to replace by dashes. Then all non-
- alpha-numeric characters get replaced, to result in IPP-
- conforming keyword strings.
- - libppd: Correct conversion between PPD option names and IPP
- attribute names, duplicate dashes like "Tray-2" -> "tray--2"
- (OpenPrinting CUPS pull request #23).
- - cups-browsed: Silenced compiler warning.
- - foomatic-rip: Fix infinite loop and input from file on raw
- printing (Pull request #318).
- - libcupsfilters: In cupsRasterParseIPPOptions() (called from
- filters used without PPD file) improved understanding of
- color mode options. Options "output-mode", "OutputMode",
- "print-color-mode", and choices "auto", "color",
- "auto-monochrome", "process-monochrome", and "bi-level" are
- supported now and default color mode is RGB 8-bit color and
- not 1-bit grayscale.
- - libcupsfilters: Added filterPOpen() and filterPClose()
- functions which similar to popen() and pclose() create a
- file descriptor which either takes data to feed into a
- filter function or provides data coming out of a filter
- function.
- - libcupsfilters: Extended ieee1284NormalizeMakeAndModel() to
- a universal function to clean up and normalize make/model
- strings (also device IDs) to get human-readable,
- machine-readable, or easily sortable make/model
- strings. Also allow supplying a regular expression to
- extract driver information when the input string is a PPD's
- *NickName.
- - libcupsfilters: Added NULL check when removing ".Borderless"
- suffixes from page size names (Issue #314).
- - libcupsfilters, parallel, test1284: Moved
- IEEE1284-device-ID-related functions into the public API of
- libcupsfilters, also made the internal functions public and
- renamed them all to ieee1284...(), moved test1284 to
- cupsfilters/.
- - foomatic-rip: Remove temporary file created during pdf-to-ps
- conversion (Pull request #313).
- - libppd: Added PPD collection handling functions (based on
- the code of cups-driverd in CUPS), for listing collections
- of PPD files and picking a PPD out of the collection. PPDs
- can be in arbitrary subdirectory structures, .tar and
- .tar.gz files, and also be generated by executables, as one
- uses them with CUPS in /usr/lib/cups/driver. This is for
- Printer Applications which retro-fit classic CUPS drivers.
- - libppd, libcupsfilters: Share the definition of logging functions
- between the two libraries, so that the same logging functions
- can be used with both.
- - Sample PPDs: Corrected manufacturer name in
- Fuji_Xerox-DocuPrint_CM305_df-PDF.ppd.
- - texttopdf: Added support for PPD-less use.
- - libcupsfilters, imagetops: Introduced imagetops() filter
- function for Printer Application to print on PostScript
- printers. It is used to print images (IPP standard requires
- at least JPEG to be accepted) without need of a PDF renderer
- (imagetopdf -> pdftops) and without need to convert to
- Raster (imagetoraster -> rastertops). The CUPS filter
- imagetops uses this filter function now, too.
- - libcupsfilters, imagetopdf: Moved core functionality of
- imagetopdf into the imagetopdf() filter function.
- - libcupsfilters, imagetoraster: Moved core functionality of
- imagetoraster into the imagetoraster() filter function.
- - sys5ippprinter, cups-browsed: Removed sys5ippprinter, as
- CUPS does not support System V interface scripts any
- more. This first approach of PPD-less printing was also not
- actually made use of.
- - libcupsfilters, gstoraster, gstopdf, gstopxl: Moved core
- functionality of gstoraster into the ghostscript() filter
- function.
- - braille: Support new liblouis tables not containing a
- display name (Pull request #303)
- - libcupsfilters: Added filterChain() filter function to run
- several filter functions in a chain.
- - libcupsfilters, pdftopdf: Moved core functionality of
- pdftopdf into the pdftopdf() filter function (Pull request
- #301, #307).
- - Build system: Let ./configure not error out when there is
- more than one DejaVuSans.ttf test font candidate or if there
- is no DejaVuSans.ttf at all installed (Issue #300, #411).
- - cups-browsed: Crash when a remote printer set as default
- gets removed, due to missing variable in printf() call
- (Issue #299).
- - COPYING: Fixed several typos
- - libcupsfilters: Fixed typo in log message of
- get_printer_attributes functions.
- - cups-browsed: Fixed typos in configuration file and man page
- - libcupsfilters: Let the PPD generator not suffix page size
- names with ".Borderless" if all page sizes would get this
- suffix, for example for printers which generally print
- borderless.
- - driverless, driverless-fax, libcupsfilters: Added IPP Fax
- Out support. Now printer setup tools list an additional fax
- "driver". A fax queue is created by selecting this
- driver. Jobs have to be sent with "-o phone=12345" to supply
- the destination phone number (Pull request #280, #293,
- #296, #302, #304, #305, #306, #309, Issue #298, #308).
- - libfontembed: Silenced warning with gcc 10.x (Pull request
- #287).
- - libcupsfilters, rastertopdf, rastertopclm: Moved core
- functionality of rastertopdf into the rastertopdf() filter
- function (Pull request #288, #289).
- - cups-browsed: Added ./configure options
- --enable-saving-created-queues and
- --with-remote-cups-local-queue-naming (Pull request: #253,
- #285).
- - libcupsfilters, pclmtoraster: Moved core functionality of
- pclmtoraster into the pclmtoraster() filter function (Pull
- request #275).
- - libcupsfilters, rastertops: Moved core functionality of
- rastertops into the rastertops() filter function (Pull
- request #282, #290).
- - cups-browsed: Fixed several memory leaks, mainly from the
- code to merge printer IPP attributes for clusters (Pull
- request #281, #283, #311, #322).
- - libcupsfilters: Started adding functions to read out IPP
- attributes from the job and check them against the IPP
- attributes (capabilities) of the printer:
- ippAttrEnumValForPrinter(), ippAttrIntValForPrinter()
- - driverless: Added "--std-ipp-uris" command line option to
- show listed URIs in standard hostname-based form (not the
- CUPS DNS-SD-service-name-based form. Only for manual call of
- the utility, for debugging purposes (Pull request #277).
- - libfontembed: Removed assert() calls which cause crashes
- when unsupported emoji fonts are installed (Issue #254, Pull
- request #276).
- - driverless: Added support for IPPS (use "ipps://..." URIs if
- possible, Issue #251, Pull request #270, #273).
- - libcupsfilters, pdftops: Moved core functionality of pdftops
- into the pdftops() filter function.
- - libcupsfilters, bannertopdf, gstoraster, pdftops: Moved
- common PDF/QPDF functions (pdf.cxx/pdf.h) into
- libcupsfilters.
- - libcupsfilters, bannertopdf, sys5ippprinter, texttotext,
- pdftops: Moved portability implementations (getline.c,
- strcasestr.c) into libcupsfilters.
- - libcupsfilters, pstops: Added filterCUPSWrapper()
- convenience function to easily create a classic CUPS filter
- from a filter function.
- - gstoraster, gstopdf: When converting PostScript to PDF use
- the "pdfwrite" output device with "-dPDFSETTINGS=/default"
- instead of with "-dPDFSETTINGS=/printer". This reproduces
- bitmaps in the PostScript file with their original image
- quality (Issue #272).
- - pdftops: Replaced the external program call of CUPS' pstops
- filter by the pstops() filter function of libcupsfilters.
- - lincupsfilters: Added the filter functions concept and added
- CUPS' pstops filter as the first working model of a filter
- function. All filters will get converted into filter
- functions to make it easier to use them in Printer
- Applications.
- - cups-browsed: Limit log file size and add backup file for
- previous log entries. Introduced the configuration option
- DebugLogFileSize in cups-browsed.conf to set the actual
- limit in kilobytes or 0 to get the old behavior of an
- unlimited size for the log file (Issue #260, Pull request
- #267).
- - gstoraster, gstopdf: Do not apply margins when output format
- is PDF, as then we convert an incoming PostScript file to
- PDF (pre-pdftopdf) and do not prepare the pages for the
- printer (post-pdftopdf, Issue #250).
- - cups-browsed: Do not write any log messages directly to
- stderr, there were some concerning timeouts on queue
- creation (Issue #260).
- - Build system: Fix cross-compilation without DejaVu test font
- in configure.ac (Issue #262, Pull request #263).
- - libcupsfilters, libppd: Respect the fact that PPD keywords
- are case-sensitive when adding "*cupsManualCopies: True" in
- PPD file (Issue #242).
- - Build system: Remove '-D_PPD_DEPRECATED=""' from the
- compiling command lines of the source files which use
- libcups. The flag is not supported any more for longer times
- already and all the PPD-related functions deprecated by CUPS
- have moved into libppd now.
- - libcupsfilters, libppd: Older versions of libcups (< 2.3.1)
- had the enum name for fold-accordion finishings mistyped.
- Added a workaround.
- - cups-browsed: Remove left-over local queues from the
- previous session more quickly when CUPS legacy browsing is
- turned on.
- - cups-browsed: Left-over local queues from the previous
- session for which the corresponding remote printer did not
- appear again did not get removed as they were considered
- externally overwritten.
- - gstoraster, gstopdf: Add option "-dDoNumCopies" to
- Ghostscript command line if we are outputting PDF (called
- via gstopdf wrapper) and the number of copies supplied to
- CUPS is 1 (4th command line argument). In this case we
- convert incoming PostScript to PDF and need to respect
- embedded PostScript commands to implement the number of
- copies (Issue #255, CUPS Issue #5796, OpenSUSE bug
- #1173345).
- - imagetoraster: Potential null dereference fix (when no valid
- PPD is supplied, Pull request #256).
- - libppd: Added the new libppd library overtaking all the PPD
- handling functions from libcups as they are deprecated there
- and will probably get removed with the next CUPS
- version. This form of conservation is mainly intended for
- converting classic printer drivers which use PPDs into
- Printer Applications without completely rewriting them. Side
- effect that all the compiler warnings about deprecated
- libcups functions went away and so cups-filters is free of
- warnings again. The library still needs some testing and
- optimization.
- - Sample PPDs: Renamed source directory from "ppd/" to
- "ppdfiles/"
- - cups-browsed: Call cupsGetNamedDest() only if
- "OnlyUnsupportedByCUPS No"
- - Sample PPDs: Corrected ColorModel default for Generic PWG
- Raster PPD to Color (Pull request #247).
- - cups-browsed: Mark the temp queue as cups-browsed-generated
- during setting printer-is-shared (Pull request #246).
- - cups-browsed: Remove mentions of README and AUTHORS files in
- the man page (Pull request #244).
- - pclmtoraster: Added new filter to extract Raster data from
- raster-only PDF files, here for the special case of PCLm
- files (Pull request #243, #257).
- - Sample PPDs: In Generic-PDF_Printer-PDF.ppd add option to
- switch between color and grayscale printing (Pull request
- #237).
-
-CHANGES IN V1.27.5
-
- - cups-browsed: Do not remove the created local queues on
- shutdown, to avoid their re-creation on restart, so that
- desktops get no cluttered with notifications of new queues
- being created. One can return to the old behavior via
- "KeepGeneratedQueuesOnShutdown No" in cups-browsed.conf
- (Ubuntu bug #1869981, #1878241).
- - cups-browsed: Do not accept DNS-SD broadcasts of IPPS type
- of "remote" CUPS queues of another CUPS instance on the
- local machine. This way we get a local queue pointing to
- such a printer only in unencrypted version (IPP). For some
- reason printing from one CUPS server to another on the same
- machine works only unencrypted.
- - foomatic-rip: Map two-sided-short-edge to DuplexTumble (Pull
- request #236)
- - Build system: In configure.ac use AS_IF instead of
- AC_CHECK_FILE for font check (Issue #239, Pull request #240)
- - cups-browsed: Cleaned up code for determining to which CUPS
- server (host/port/domain socket) to connect, so that
- connection via DomainSocket cups-browsed.conf directive,
- CUPS_SERVER and IPP_PORT environment variables and all
- defaults and methods of libcups, including CUPS' client.conf
- work.
- - gstoraster, rastertopdf: Do not pass NULL to fprintf() (Pull
- request #230).
- - libcupsfilters: Silence compiler warning (Pull request #229).
-
-CHANGES IN V1.27.4
-
- - libcupsfilters, cups-browsed: Fix memory issues in
- ppdgenerator and cups-browsed (Pull request #226).
- - pdftops: Mention cups-filters README, CUPS README in debug
- log (Pull request #225).
- - pdftopdf, gstoraster, foomatic-rip: Use "-dSAFER"
- Ghostscript option, instead of the deprecated
- "-dPARANOIDSAFER" (Pull request #224).
- - Build System: Replace '==' in configure.ac test with '=', as
- the former is a bashism (Pull request #222).
-
-CHANGES IN V1.27.3
-
- - cups-browsed: Allow sharing local queues pointing to remote
- CUPS queues and re-sharing printers discovered via
- BrowsePoll by default, using
- AllowResharingRemoteCUPSPrinters and
- NewBrowsePollQueuesShared directives in cups-browsed.conf
- (Issue #101, Pull request #218).
- - driverless: Correctly unlink temporary file when generating
- PPD file (Pull request #220).
- - cups-browsed: Fixed memory leaks (Pull request #219).
- - foomatic-rip: PDF page count side-loads the PDF file to
- count the pages in, so it cannot be run in -dSAFER mode. Run
- even in -dNOSAFER mode to override the -dSAFER default of
- newer Ghostscript versions. This should not cause a security
- problem as we do not take an input file which could do
- arbitrary side-loads but we run hard-coded PostScript
- commands instead (Issue #216).
- - libfontembed: Add checks to the test programs to not
- segfault if the test font file is not found (Pull request
- #214).
- - Build System: Let ./configure fail if the supplied test font
- file path (or the default) does not exist (Pull request
- #214), also use the "find" command to find the test font
- file DejaVuSans.ttf under /usr/share/fonts, as every
- distribution has it somewhere else.
-
-CHANGES IN V1.27.2
-
- - foomatic-rip: In some PostScript input files it was possible
- that option settings did not get inserted or lines inserted
- on the wron place (Issue #208, Pull request #210).
- - foomatic-rip: For the PDF page count call Ghostscript in
- sandbox mode and fix pointer arithmetics (Pull request
- #212).
- - foomatic-rip: Zero-page-job handling changes made the last
- page of PostScript files not printed, also turning one-page
- jobs into zero-page jobs (Issue #200, Issue #206, Issue
- #208, Pull request #209, Pull request #210, Pull request
- #211).
- - cups-browsed: check_printer_with_option() function:
- Initialize the value, add further checks, freeing memory and
- stop allocating magic numbers (Pull request #204).
- - cups-browsed: Additional checks against crashes in the
- is_local_hostname() function (Ubuntu bug #1863716)
-
-CHANGES IN V1.27.1
-
- - libcupsfilters: Let the PPD generator not put any dashes
- into the PPD option and choice names when translating them
- from IPP attribute names, to avoid that on the
- back-translation by CUPS no double-dashes are
- generated. This broke paper tray selections with tray names
- like "tray-1", "tray-2", ... (Issue #192, Issue #201, Debian
- bug #949315).
- - foomatic-rip: Fixed segfault when PRINTER environment
- variable is not supplied.
- - pdftopdf, pdftops, gstoraster, gstopdf, gstopxl,
- rastertoescpx, rastertopclx, foomatic-rip: Handle zero-page
- jobs (Issue #117, Pull request #196, Pull request #197, Pull
- request #198, Pull request #200).
- - texttopdf: Added support for CJK (double-width) fonts (Issue
- #135, Pull request #199).
- - cups-browsed: Switched default for "CreateIPPPrinterQueues"
- from "local-only" to "All". The configure script options
- "--enable-auto-setup-local-only" and
- "--enable-auto-setup-driverless-only" can be used to change
- this default (Debian bug #921252).
- - rastertoescpx: Fixed wrong freeing of a buffer.
- - pdftops: Added options "crop-to-fit" and "fill" to the
- pdftopdf options which the pstops called by pdftops should
- not apply a second time.
- - pdftops: Added missing "-sstdout=%stderr" to Ghostscript
- command line, to assure that all messages are redirected to
- stderr and do not mix up with the output data.
-
-CHANGES IN V1.27.0
-
- - cups-browsed: Eliminate the use of the local CUPS daemon's
- (the CUPS we are attached to) port number completely, so
- that for attaching to an arbitrary local CUPS daemon
- listening on an arbitrary port (or even not listening on
- localhost at all) it is enough to tell cups-browsed the
- domain socket the CUPS daemon is listening on.
- - cups-browsed, libcupsfilters: Identify DNS-SD-reported
- printers as of the local CUPS daemon via UUID and not via
- the port on which the local CUPS is listening, as we do not
- always have this port available.
- - cups-browsed: Leave the port for legacy CUPS browsing and
- broadcasting on 631, do not use a possible alternative port
- of the CUPS we are attached to. The legacy CUPS servers we
- communicate with are always remote ones.
- - libcupsfilters: in the PPD generator prioritize
- print-color-mode-supported against
- pwg-raster-document-type-supported (Issue #186, Pull request
- #188)
- - rastertopdf, rastertops, texttopdf, pdftoraster,
- mupdftoraster: Handle zero-page jobs, corrections on
- zero-page job handling (Issue #117)
- - cups-browsed: When restarting after a crash make sure that
- local queue names have same upper/lower case as before.
- - cups-browsed: Small code improvements to reduce crash
- probability.
-
-CHANGES IN V1.26.2
-
- - cups-browsed: Added crash guards to avoid crashes in case
- the dummy printer entry for a deleted master entry is used.
- - cups-browsed: Set the port of the local CUPS daemon to be
- used according to the IPP_PORT environment variable.
- - cups-browsed: Eliminated the use of the cupsGetPPD2()
- function of libcups completely, also the remaining calls
- in the record_printer_options() and update_cups_queues()
- functions, the former causing incomplete recording of
- option settings and the latter use of CUPS-generated
- PPDs not working when CUPS is running on a non-standard
- port.
- - cups-browsed: Eliminated the use of the cupsGetPPD2()
- function of libcups in queue_overwritten(). The function
- actually loads the queue's PPD file if the queue is on a
- local CUPS on port 631. Due to a bug the function fails if
- an alternative port is used. This lets queue_overwritten()
- always assume that the PPD got removed and therefore the
- queue got overwritten. So queues got released from
- cups-browsed if it was printed on them or if they were
- supposed to be removed on shutdown.
- - foomatic-rip: Fixed compilation with -fno-common. Starting
- from the upcoming GCC 10, the default of the -fcommon option
- will change to -fno-common. This causes compilation errors
- in foomatic-rip due to missing "external" declarations.
- (Pull request #184).
-
-CHANGES IN V1.26.1
-
- - build system: Install the "implicitclass" backend with
- "-rwx------" permissions, so that CUPS executes it as root,
- as the "ipp" CUPS backend also has to be executed as root
- (Issue #183).
- - build system: Fixed setting permissions when installing the
- "cups-brf" backend.
- - libcupsfilters: When using the
- "media-{bottom,left,right,top}-margin-supported" IPP
- attributes (needed if we have no "media-col-database"), use
- the minimum and not the maximum margins, this allows
- accessing more of the printer's capabilities, especially for
- legacy printers which do not provide sufficient information
- (Issue #22).
-
-CHANGES IN V1.26.0
-
- - cups-browsed: When generating local queues for printers for
- which the local CUPS daemon would provide temporary queues
- use the PPDs generated by libcupsfilters and not the ones
- generated by CUPS. The PPD generation of libcupsfilters also
- works with IPP-1.x-only printers, printers which do not
- support to query "media-col-database" and printers which
- support driverless printing only via PCLm. This can be
- changed via the "UseCUPSGeneratedPPDs" directive in
- cups-browsed.conf (Issue #22).
- - libcupsfilters: Re-structured the get_printer_attributes()
- function to remove the recursive calls for the fallbacks, to
- check required attributes in the response only if requested,
- and to fully integrate the method of getting a suitable
- response for a full printer capability list also if the
- printer is only IPP 1.1 or does not support the
- "media-col-database" attribute (Issue #22, Issue #163).
- - libcupsfilters, cups-browsed, driverless: Moved the funtions
- get_printer_attributes() and resolve_uri() from cups-browsed
- into libcupsfilters, to share them with the driverless
- utility (Issue #22).
- - implicitclass: Fixed wrong stdout redirection from the
- filters to the IPP backend and hard-coded path for "ipp"
- backend call (Possible fix for Issue #163, Issue #181).
- - cups-browsed, driverless: Use DNS-SD-service-name-based URIs
- instead of host-name-based ones, as CUPS also does. In
- cups-browsed one can switch back to the conventional
- host-name-based URIs via the new "DNSSDBasedDeviceURIs"
- configuration option. Note that cups-browsed always uses
- conventional URIs for printers discovered via legacy CUPS
- browsing or LDAP.
- - cups-browsed: When removing a CUPS queue, do not consider an
- error (and retry) if the queue does not actually exist. Also
- ignore errors when checking whether there are still
- jobs. This way when a new queue gets created and the
- generation of the PPD file fails the attempt to remove this
- non-existing queueu when removing the printer entry does not
- cause any problem.
- - cups-browsed: Improved the fallback mechanism of the
- get_printer_attributes() function. Instead of considering
- the request failed by the content of the response only when
- not more than the two language atrributes come out, we check
- through a list of required attributes whether they are all
- there. In addition, we actually fail when all callbacks
- have failed (Issue #22).
- - cups-browsed: Introduced new configuration options
- "UpdateCUPSQueuesMaxPerCall" and
- "PauseBetweenCUPSQueueUpdates" to limit the amount of local
- CUPS queues created, modified, or removed in a single event
- callback. Before, when there were thousands of printers in
- the network, cups-browsed got blocked for other tasks, like
- assigning a destination printer for a cluster print job
- (Issue #163).
-
-CHANGES IN V1.25.13
-
- - implicitclass: When passing on the job via the "ipp" CUPS
- backend, set argv[0] to the destination printer URI (Pull
- request #173).
- - cups-browsed: Added another fallback to the
- get-printer-attributes IPP request: Now after failing the
- standard request ("all", "media-col-database") with both IPP
- 2.0 and IPP 1.1, try simply "all", without
- "media-col-database" (Pull request #173).
- - cups-browsed: Do not set printer-is-shared for remote CUPS
- queue when making a temporary queue permanent (Pull request
- #180).
- - cups-browsed: Fix leaks of ipp_t struct and load balancing
- on the servers (Pull request #179).
- - cups-browsed, implicitclass: Prioritize Apple Raster against
- PWG Raster when selecting the PDL for the destination
- printer for a job sent to a cluster, also cleaned up the PDL
- selector code and added PostScript support.
- - libcupsfilters: Updated the PPD generator adding all changes
- of the PPD generator of CUPS: Support for "job-account-id",
- "job-accounting-user-id", "job-password", finishing options
- "trim-..." added, finishing options and
- "finishing-col-database" support synced with CUPS.
- - libcupsfilters: In the PPD generator get the mode for
- handling the back sides of the sheets when printing duplex
- preferrably from the "urf-supported" attribute.
- - libcupsfilters: Fixed bug that the PPD generator did not
- output the "*CloseUI: *ColorModel" line when it did not
- determine a default setting for "ColorModel".
- - cups-browsed: Added some missing memory allocations leading
- to a segfault (Issue #175).
-
-CHANGES IN V1.25.12
-
- - libcupsfilters: Use the text names "Draft", "Normal", and
- "High" instead of 3, 4, and 5 as choice names for the
- "cupsPrintQuality" option as CUPS does (Issue #171).
- - libcupsfilters: If a printer supports both Apple Raster and
- PWG Raster let the generated PPD use Apple Raster as there
- are several printers which report PWG Raster support but do
- not actually print PWG Raster (Pull reguest #168, Issue
- #171, CUPS issue #5238).
- - cups-browsed: Fix unset location check to use DNS-SD field
- (Pull request #172).
- - libcupsfilters, beh, implicitclass, foomatic-rip,
- imagetopdf, mupdftoraster, pdftops, sys5ippprinter,
- cups-browsed, driverless: Silenced all compiler warnings to
- make the build process of cups-filters completely free of
- warnings.
- - pdftops: Fixed crash when using filter without PPD file.
- - pdftops: If printing grayscale jobs with Ghostscript as PDF
- renderer, add "-sProcessColorModel=DeviceGray" to
- Ghostscript command line.
- - pdftops: Do not use the ugly "pdftops -level1 ..."
- workaround to get grayscale PostScript output from
- Poppler. It leads to huge output files with Poppler's
- "pdftops" utility and does not work at all with
- "pdftocairo". Poppler itself does not support PostScript
- output converted to grayscale. Issue a warning with the hint
- to use Ghostscript or MuPDF as PDF renderer (Issue #169).
- - libcupsfilters: In the cupsRasterParseIPPOptions()
- accept also "Mono", "Monochrome", and "Gray" as color
- space names.
-
-CHANGES IN V1.25.11
-
- - cups-browsed: Really accept entries without printer name
- reported on a job status request (Issue #163).
- - cups-browsed: Strip IPP attribute values reported by the
- printer on a get-printer-attributes request from white
- space (Pull request #166).
-
-CHANGES IN V1.25.10
-
- - libcupsfilters: Added NULL checks when handling page size
- names as some of the page sizes in CUPS' PWG media list have
- a NULL PPD name (Ubuntu bug #1847488).
-
-CHANGES IN V1.25.9
-
- - cups-browsed: Fix leaks in get_printer_attributes() function.
- - cups-browsed: Avoid infinite recursion on IPP 1.1 fallback.
-
-CHANGES IN V1.25.8
-
- - cups-browsed: On a job status request accept also entries
- without the printer name being reported (Issue #163).
- - cups-browsed: Fall back to IPP 1.1 if a
- get-printer-attributes IPP request with IPP 2.x fails (Issue
- #124, Issue #163).
- - gstoraster: Use ".setfilladjust2" instead of the
- undocumented ".setfilladjust" PostScript command for
- Center-of-Pixel method to fill paths (Issue #164).
-
-CHANGES IN V1.25.7
-
- - implicitclass, libcupsfilters: Fixes to solve an assertion
- error and printing to an Apple Raster printer (Issue #162,
- Ubuntu bug #1845286, Ubuntu bug #1845548).
- - cups-browsed: Do not try to resolve the network interface
- name on Avahi messages which are not interface-related (like
- "All for now"or "Cache exhausted", Issue #163).
- - Build system: The helper script ln-srf to build on systems
- with old ln was not included in the release tarballs (Issue
- #161).
- - pdftoraster: Fixed some bugs in output bitmap generation (
- writePageImage() function): Segfault on output of
- up-side-down pages (back side when printing duplex on some
- printers), margin offsets not taken into account on
- monochrome jobs, CUPS_CSPACE_W color space not recognized as
- monochrome (Ubuntu bug #1845286).
-
-CHANGES IN V1.25.6
-
- - implicitclass: Make sure the destination printer gets always
- set and do not pass on the cups-browsed-dest-printer when
- sending the job to the final destination (Issue #152, Pull
- request #159).
- - Build system: Support old ln versions without the -r option
- (Pull request #154, #157).
- - texttotext: Link with libiconv if needed (Pull request
- #155, #158).
- - foomatic-rip: Fix argument representation for raw queue
- debug mesaage (Pull request #153).
-
-CHANGES IN V1.25.5
-
- - bannertopdf: Added missing "#include <cstring>" to pdf.cxx
- so that bannertopdf correctly builds with QPDF 9.0.0 (Issue
- #134, Issue #151, Gentoo bug #693498).
- - rastertopdf: Let the getIPPColorProfileName() function not
- return a pointer to a local variable (clang warning, Issue
- #150).
- - cups-browsed: If a locally generated queue (usually with
- "implicitclass://..." URI) left over from a previous
- (crashed) session is picked up on startup, do not set the
- URI as the remote printer's URI and do not cause a fatal
- error on a failed get-printer-attributes IPP request (Issue
- #148, Debian bug #939316).
- - pdftopdf: Do not preserve encryption, since the output
- already goes into the printer (Issue #146, Pull request
- #147).
-
-CHANGES IN V1.25.4
-
- - imagetoraster: Do not call imagetops and pstoraster for
- classifications and page labels as these filters are not
- included any more with cups-filters. Classifications and
- page labels are currently not supported for direct image
- printing, only for PDF or PostScript input (which goes
- through pdftopdf).
- - imagetoraster, imagetopdf: Fixed auto-rotation of images to
- fit output page best (Issue #145).
- - pdftoraster: If the PPD contains several equally-sized page
- size entries which match the size of the input page and one
- is the size selected by the user via the "PageSize" or
- "media" option (or the default selection in the PPD) then
- prefer this one instead of simply the first matching one.
- - pdftoraster: If the input page size cannot be matched with
- one of the PPD's page sizes it is considered a custom size,
- fill the page size name field of the CUPS Raster header with
- "Custom.XXXxYYY" then.
- - pdftoraster: Match the input page size with a page size in
- the PPD only if the differences of the dimensions are less
- than 1%, also match the input page size against the
- imageable area of the PPD's page sizes if no match with the
- full page size is found (Issue #138).
-
-CHANGES IN V1.25.3
-
- - Sample PPDs: In HP-Color_LaserJet_CM3530_MFP-PDF.ppd renamed
- "custom" choice of the option "stapleoption" to "customsize"
- as from CUPS 2.2.12 on "custom" is not accepted any more as a
- choice name in a PPD file.
- - cups-browsed: Fixed check whether the remote printer understands
- PWG Raster (Issue #141).
-
-CHANGES IN V1.25.2
-
- - foomatic-rip: Fixed segmentation fault when running
- foomatic-rip by hand and the PRINTER environment variable is
- not set (Pull request #139).
- - cups-browsed: Added note to cups-browsed.conf and man page
- about IP-based URIs depending on the network interface used.
- - cups-browsed: For each DNS-SD-discovered printer register
- each DNS-SD discovery instance with network interface,
- family, and IPP type. When DNS-SD messages of instances
- disappearing show up, only unregister this instance and
- remove the printer only if no instance is left. This
- prevents a local queue of a still available printer being
- removed when Wi-Fi (= one interface) is turned off (Issue
- #136).
- - cups-browsed: If a remote printer is served from the local
- machine, prefer the "localhost"/loopback interface URI.
- - cups-browsed: If a remote printer is discovered more than
- once, use the new instance only if it has no downgrades and
- at least one upgrade compared to the old one. Features
- currently compared are IPP/IPPS, loopback interface or not,
- and discovery via CUPS legacy/LDAP/DNS-SD.
- - cups-browsed: If an Avahi-discovered entry comes through the
- "lo" interface, always use the host name "localhost". Use
- IP addresses instead of host names only if explicitly
- requested.
- - cups-browsed: Consider remote printer entries also as from
- the same printer if one has the local machine's network name
- and the other "localhost" as host name (Issue #136).
-
-CHANGES IN V1.25.1
-
- - imagetopdf: Fixed crash when no PPD file was supplied (Pull
- request #133).
- - pdftoraster: Fixed offset issues leading to segmentation
- faults (Issue #131, Pull request #132).
- - pdftoraster: Added anti-aliasing for better raster image
- quality (Pull request #129).
- - pdftoraster: Added graceful handling of zero-page input
- (Issue #117, Pull request #127).
-
-CHANGES IN V1.25.0
-
- - pdftoijs, pdftoopvp: Removed these deprecated filters
- completely as there is no demand for them any more. They
- also used unstable, undocumented APIs of Poppler.
- - pdftoraster: Changed from using unstable, undocumented APIs
- of Poppler to stable, documented ones, to improve
- maintainability of this filter, and with it of the
- cups-filters package. Thanks to Tanmay Anand for
- contributing this as his Google Summer of Code 2019 project.
- - libcupsfilters: Added support for color spaces CMY and RGBW
- when using filters without PPD file (mainly for development
- and debugging, option "print-color-mode" with values
- "cmy-XX" and "rgbw-XX" with XX being the number of bits per
- color).
-
-CHANGES IN V1.24.0
-
- - cups-browsed: Integration of Deepak Patankar's Google Summer
- of Code 2018 project with the main goal of clustering
- different printers and automatically selecting the
- destination printers by job content and option/attribute
- settings. All changes of this release are done by Deepak as
- parts of his project.
- - cups-browsed, implicitclass: Support for mixed clusters of
- remote CUPS queues and IPP network printers. For this PPD
- files of remote CUPS queues are generated by cups-browsed
- based on IPP queries, as for native IPP printers, the number
- of jobs for load balancing is polled in a way that it works
- also with native IPP printers, the implicitclass backend
- sends jobs directky to the printer instead of re-queueing
- them via CUPS.
- - cups-browsed: Merge IPP attributes of several printers to
- combined attributes for the cluster to generate the
- cluster's PPD file, including PPD constraints for option
- combinations not fulfillable by any of the member printers,
- and finding reasonable, non-conflicting default settings,
- - cups-browsed: Selection algorithm for the destination
- printer for a job sent to the cluster. Based on the job
- settings requested such as page size, media type, print
- quality, ... the best most suitable printer in the cluster
- for the job will be selected.
- - cups-browsed, implicitclass: Filter jobs to clusters already
- locally. Due to the fact that a cluster's member printers
- are not exclusively non-raw CUPS queues with the complete
- filtering framework on the remote server, but also native
- IPP printers, we need to support generic driverless printers
- as destination. So we cannot pass on the input data
- unfiltered but need to filter locally. We let the cluster's
- PPD file emulate a PDF printer, letting the local CUPS queue
- of the cluster run pdftopdf and any pre-filters to turn the
- input into PDF and we let the implicitclass backend turn PDF
- into a format understood by the destination printer,
- supporting the 4 formats of driverless IPP printing: PDF,
- PWG Raster, Apple Raster, PCLm.
-
-CHANGES IN V1.23.0
-
- - pdftops, mupdftoraster: Let pdftops call mutool directly and
- so that it directly outputs PostScript, eliminating the need
- to call the mupdftoraster and rastertops filters.
- - mupdftoraster: Reduced the use of temporary files from 3 to
- just one.
- - imagetopdf, imagetoraster, pdftopdf: Add support for
- print-scaling option (Issue #108, Pull request #118).
-
-CHANGES IN V1.22.6
-
- - rastertops: Fixed PageSize settings in the PostScript output
- (Must be in points not in pixels).
- - pdftops, mupdftoraster: Produce actual grayscale/monochrome
- PostScript (and not only instructions to print grayscale/
- monochrome) for jobs to be printed in grayscale/monochrome
- (Issue #96, Pull request #115).
- - mupdftoraster: Fixed filter not producing output at all.
- - Build system: ENABLE_DRIVERLESS got only defined with CUPS
- 1.6 and newer, not with older CUPS versions (Issue #111).
- - pdftopdf, imagetopdf, imagetoraster: Silenced compiler
- warnings.
- - cups-browsed, driverless: Replaced httpConnect() calls by
- httpConnect2() calls as the former CUPS library function is
- deprecated.
- - Build system: Compile everything using the CUPS libraries
- with '-D_PPD_DEPRECATED=""' for the time being until the
- deprecated PPD API calls get replaced, to stop the flooding
- with PPD API deprecation warnings making more important
- warnings being overlooked.
- - cups-browsed: When removing a local queue on shutdown or
- when DNS-SD reports the printer as disappeared check whether
- the local queue got overwritten by an external process as
- sometimes the shutdown or disappearing event comes too close
- for cups-browsed receiving a printer-modified notification
- from CUPS before (Ubuntu bug #1731417).
-
-CHANGES IN V1.22.5
-
- - foomatic-rip: Changed Ghostscript call to count pages in a
- PDF file to use "runpdfbegin" and not the undocumented
- Ghostscript internal "pdfdict", so that it works with
- Ghostscript 9.27 and later (Debian bug #926576, Arch Linux
- bug #62251).
-
-CHANGES IN V1.22.4
-
- - cups-browsed: Fix broken trailing space removal on
- "NickName" (Pull request #103).
- - pdftops: Emit PostScript Level 2 instead of Level 3 for
- Brother PostScript printers as at least some of them
- report to support level 3 but ontly work with Level 2
- (Ubuntu bug #1306849, comment #42).
- - bannertopdf: When multiplying the page for N-up or Duplex
- printing one page too much was generated (Issue #102).
-
-CHANGES IN V1.22.3
-
- - libcupsfilters: Added error checks for processing GIF, to
- avoid crashes or hangs on broken GIF files (Issues #81, #82,
- Pull request #100).
- - cups-browsed: Added hint to the man page and configuration
- file that with "DebugLogging stderr" the logging output goes
- to journal or syslog if cups-browsed is running as system
- service (Issue #28).
-
-CHANGES IN V1.22.2
-
- - cups-browsed: Let distribution of jobs sent to queues with
- "implicitclass" backend (usually clusters) be done by a
- "job-state" CUPS notification and not by
- "printer-state-changed" any more. The "job-state"
- notification already contains the job ID. Before we had to
- poll the job ID from CUPS via IPP which was sometimes
- unreliable (Issue #97).
- - imagetopdf, imagetoraster, pdftopdf, libcupsfilters: Added
- new page scaling options: "fill" scales the input page
- (typically a photo) so that the output page (typically with
- different aspect ratio) gets completely filled, aloowing for
- some content of the input page getting lost. "crop-to-fit"
- allows for easy printing of documents on slightly different
- output page sizes (A4 <-> Letter) maintaining the size and
- centering and cropping into the destination page. Thanks to
- Dheeraj Yadav (dhirajyadav135 at gmail dot com) for the
- patch (Pull request #92).
- - cups-browsed: Do not do IPP request for printer-is-shared
- option for remote cups queues with CUPS 2.2.x and newer
- (Pull request #91).
- - cups-browsed: Fix crash bug when reading "Cluster"
- directive from configuration file (Issue #94).
- - driverless: Updated man page as now also Mopria and
- Wi-Fi Direct printers are supported. Mentioned also
- ippusbxd.
-
-CHANGES IN V1.22.1
-
- - braille: Use sort command with LC_ALL=C for reproducibility
- of the genrated files, needed for distribution packaging.
- - cups-browsed, driverless: When polling the printer's
- capabilities via get-printer-attributes IPP request for
- driverless printing, use the attributes "all" and
- "media-col-database". Without "all" some printers do not
- report "urf-supported" and without "media-col-database" not
- all paper size and marging info gets reported (Issue #22,
- Pull request #86, CUPS issue #5484).
- - braille: Document how to rework output before
- embossing. Thanks to Samuel Thibault for this patch (Pull
- request #90).
-
-CHANGES IN V1.22.0
-
- - pdftopdf: Use QPDF for flattening interactive PDF forms
- (Issues #2, #23, #36, Pull request #88).
- - pdftopdf: Fixed bug of closing temporary file prematurely
- when external PDF form flattening utilities fail (Thanks to
- Tobias Hoffmann for finding this, see pull request #88).
- - pdftoopvp: More fixes for building with Poppler 0.72
- (Pull request #83, Issue #75).
- - pdftoraster, pdftoijs, pdftoopvp: Removed support for
- Poppler 0.18 (Pull request #83).
- - cups-browsed: Fixed crash in applying the BrowseFilter
- cups-browsed.conf directives (Debian bug #916765).
-
-CHANGES IN V1.21.6
-
- - cups-browsed: To find out whether a DNS-SD-discovered
- printer is from the local machine, use not only the flags in
- the Avahi lookup result but also check the host name.
- - cups-browsed: When a local CUPS queue pointing to a remote
- CUPS printer was removed and re-created to make it a
- permanent queue, on_printer_deleted() was triggered by
- cupsd's notification to re-create a lost queue. Now
- on_printer_deleted() checks whether the queue is really gone
- and only re-creates then (Issue #80).
- - cups-browsed: When updating the CUPS queues, also removed
- and unregistered queues and not only created queues got
- checked for HTTP timeouts, which caused crashes on shutdown
- (Issue #79, Debian bug #916149).
- - pdftops: Use the PS interpreter of Poppler for all Apple
- LaserWriter 16/600, 4/600, 12/640, 12/600, 12/660 as they
- all seem to not work with Ghostscript's PS output (Issue
- #76).
- - cups-browsed: On shutdown queues got removed even if they
- still had jobs (Debian bug #908147).
-
-CHANGES IN V1.21.5
-
- - cups-browsed: We cannot reliably determine whether a CUPS
- queue is temporary, so we apply the procedure to make a
- temporary queue permanent to any unshared queue (Debian bugs
- #910882, #905850, #908604).
- - pdftoraster, pdftopdf, pdftoijs, pdftoopvp: Do not use the
- Poppler-specific "GBool", "gFalse", "gTrue" any more, as
- Poppler has switched to standard "bool", "false", "true" in
- version 0.71.0 (Issue #69).
-
-CHANGES IN V1.21.4
-
- - cups-browsed: Limit the number of retries for
- creating a print queue when it comes to HTTP
- timeouts. Number of retries given by HttpMaxRetries
- directive in cups-browsed.conf. Thanks to Zdenek Dohnal for
- the patch (Pull request #73, Red Hat bug #1648697).
- - cups-browsed: Read out current time right before setting the
- timeouts. Thanks to Zdenek Dohnal for the patch (Pull
- request #71, Red Hat bug #1648697).
- - libcupsfilters: In the PPD generator for driverless IPP
- printing let "*cupsManualCopies: true" lines get added to
- the PPD if printing is done in a raster format as then
- pdftopdf needs to generate the copies.
- - pdftoraster, pdftoopvp, pdftoijs: Fix build with Poppler >=
- 0.70 (Issue #69, Pull request #70).
- - pdftopdf: Fixed printing multiple copies on driverless IPP
- printers. When printing collated copies the multiple copies
- got applied twice, resulting in n*n instead of n copies
- (CUPS issue #5433).
- - pdftoraster, pdftoopvp, pdftoijs: Poppler removed memCheck
- and gMemReport functions, remove appropriate calls (Issue
- #62, Pull request #66).
-
-CHANGES IN V1.21.3
-
- - foomatic-rip: Reset stdin after replacing the underlying file
- descriptor (Issue #58).
-
-CHANGES IN V1.21.2
-
- - cups-browsed: Fixed freeing of literal string caused by
- Coverity Scan issue fix (Debian bug #907399).
-
-CHANGES IN V1.21.1
-
- - foomatic-rip: Fixed segmentation fault caused by wrong
- Coverity Scan issue fix (Issue #57, Debian bug #907026).
- - Build system: Require QPDF 8.1.0 or later as it is needed by
- bannertopdf (Issue #56).
-
-CHANGES IN V1.21.0
-
- - libcupsfilters, cups-browsed, driverless, foomatic-rip,
- parallel: Silenced warnings from newest gcc.
- - libcupsfilters: When generating a PPD for driverless
- printing on a remote IPP printer, make pdftopdf not being
- run by the local queue if the remote queue is a CUPS queue
- to avoid running pdftopdf twice (CUPS Issue #5361).
- - libcupsfilters, cups-browsed, driverless, bannertopdf,
- foomatic-rip, pdftops, pdftoraster, rastertops,
- rastertoescpx, sys5ippprinter, beh: Fixed Coverity Scan
- issues. Thanks to Zdenek Dohnal (zdohnal at redhat dot com)
- for the tests and the patches.
- - bannertopdf: Switched over from using Poppler to using QPDF
- for generating the PDF pages. With Poppler unstable APIs
- were used which were subject to change. Thanks to Sahil
- Arora for this project in the Google Summer of Code 2018
- (Pull request #25).
- - cups-browsed: Manually defined clusters ("Cluster" directive
- in cups-browsed.conf) caused cups-browsed to crash.
-
-CHANGES IN V1.20.4
-
- - README: Added link to Issue Tracker on GitHub.
- - gstoraster: Removed unneeded "if"s. Thanks to Laurent
- Martelli (martellilaurent at gmail dot com) for the patch
- (Ghostscript bug #692705).
- - cups-browsed: When checking whether there is already a local
- print queue with the same URI as the one of the discovered
- printer, consider also as equal URI if the URIs only differ
- by use of IPP or IPPS and/or use of HTTPS port 443 instead
- of IPP port 631.
- - cups-browsed: Also upgrade from ipp: to ipps: when the ipps:
- URI is on HTTPS port 443 instead of IPP port 631. This is
- common on IPP network printers.
- - pdftopdf: Removed support for hardware-implemented reversing
- of page order in PostScript printers. It was once not
- correctly implemented in cups-filters and second, such
- printers are extremely rare, and on Gutenprint PPDs with
- pseudo OutputOrder option hardware reversing was even
- wrongly assumed (Issue #47).
- - pdftopdf: Accept option "output-order=normal/reverse" for
- reversing page order (Issue #47) and also "page-delivery=
- same-order/reverse-order" (CUPS Issue #5340).
- - libcupsfilters: Let the PPD generator add "*PageStackOrder
- ..." lines to the choices of the "OutputBin" option, to
- mark which output bins need the pages printed in reverse
- order (Issue #47).
- - libcupsfilters: Let the PPD generator correctly create a
- "*DefaultOutputOrder: ..." entry, depending on whether the
- paper is put out face-up or face-down in the default output
- bin (Issue #47).
- - libcupsfilters: Fixed human-readable name of the OutputBin
- option in the PPD generator.
- - pdftoopvp: Silence compiler warning (Issue #42).
- - cups-browsed: If the user modifies/overwrites a print queue
- created by cups-browsed, it will now not only be
- automatically released from the control of cups-browsed, but
- we also create a replacement for our generated local queue
- under a new name.
- - cups-browsed: Make URIS for using the implicitclass backend
- correctly working also with queue names containing an '@'
- character.
- - braille: Strengthen error checking (Pull request #41).
- - braille: Index: Replace bogus characters with space (Pull
- request #41).
- - braille: Add print and braille page number options (Pull
- request #41).
- - braille: Index: Use standard duplex cups option (Pull
- request #41).
- - cups-browsed: Moved auto-generation of PPD file for IPP
- network printers from create_remote_printer_entry()
- function to update_cups_queues(). This allows re-creating
- accidentally removed or overwritten local queues without
- losing the PPD file.
- - braille: Add option to pick hyphenation rule according to
- current locale and make it the default for second
- translation table. Thanks to Samuel Thibault for this patch
- (Pull request #38 and #39).
- - braille: Remove generated defs on "make clean". Thanks to
- Samuel Thibault for this patch (Pull request #38).
- - braille: Turn non-breakable spaces to spaces. Thanks to
- Samuel Thibault for this patch (Pull request #38 and #39).
- - braille: Fix character encoding when extracting text. When
- extracing text from a zip file or a pdf, the resulting text
- is always utf-8 independently of the original locale, so we
- need to force that. Thanks to Samuel Thibault for this patch
- (Pull request #38).
- - braille: Warn when no text translation was selected in case
- the user didn't notice. Thanks to Samuel Thibault for this
- patch (Pull request #37).
- - braille: Fix spurious spacing after last Form-Feed (Pull
- request #45).
-
-CHANGES IN V1.20.3
-
- - braille: Do not remove read permission on cups-brf. Thanks
- to Samuel Thibault for this patch (Pull request #32).
- - braille: Get braille table descriptions from liblouis
- metadata. Thanks to Samuel Thibault for this patch (Pull
- request #31).
- - braille: Select liblouis tables based on metadata before
- using file names. Thanks to Samuel Thibault for this patch
- (Pull request #30).
- - cups-browsed: The new method of identifying remote CUPS
- queues via the "printer-type" TXT record field does not work
- for printers discovered by legacy CUPS broadcast (CUPS 1.5.x
- or older). Now consider also printers without TXT record
- (not discovered via DNS-SD) as remote CUPS queues (Issue
- #34).
- - gstoraster: Improved detection whether input is PostScript
- or PDF by skipping over possible headers. Thanks to Rod
- Schmidt (schmidtrod at q dot com) for the patch.
-
-CHANGES IN V1.20.2
-
- - cups-browsed: If the user modifies/overwrites a print queue
- created by cups-browsed, it will now automatically released
- from the control of cups-browsed, so the modified queue does
- not get removed by cups-browsed on shutdown. (Ubuntu bug
- #1731417).
- - cups-browsed: The configuration setting
- "CreateIPPPrinterQueues LocalOnly" suppressed also the
- automatic generation of local queues for remote CUPS
- printers whereas this option is only intended for physical
- IPP printers.
- - cups-browsed: Identify remote CUPS queues by the
- "printer-type" TXT record entry and not by the
- "ipp(s)://<host>/printers/<name>" URIs, there are also IPP
- network printers with such URIs (HP LaserJet Professional
- M1212nf MFP in Ubuntu bug #1731417).
- - .gitignore: Added filter/braille/filters/brftopagedbrf
- - cups-browsed, foomatic-rip: Fixed several typos. Thanks to
- Didier Raboud for the patches.
-
-CHANGES IN V1.20.1
-
- - libcupsfilters: Silenced warning when using CUPS < 2.x by
- eliminating the use of a recently introduced CUPS library
- function (Bugzilla bug #1421).
- - braille: Fix some missing options on indexv4. Thanks to
- Samuel Thibault for this patch (Pull request #21).
- - braille: Fix disabling margins on indexv4 in graphic
- mode. Thanks to Samuel Thibault for this patch (Pull request
- #20).
- - braille: Fix installation of brftopagedbrf. Thanks to Samuel
- Thibault for this patch (Pull request #18, Issue #17).
- - cups-browsed: Fixed crash when CUPS reports a print queue
- without "device-uri" attribute when cups-browsed polls a
- list of local CUPS queues (Issue #16).
-
-CHANGES IN V1.20.0
-
- - libcupsfilters: Let the PPD generator prefer the English
- translation file from CUPS for the human-readable strings in
- the PPD files.
- - libcupsfilters: The PPD generator lists all page sizes with
- human-readable names now, including proprietary names of the
- printer.
- - cups-browsed, driverless: Fixed get-printer-attributes call
- on driverless printers for generating the PPD, explicitly
- requesting the media-col-database attribute as otherwise
- borderless page sizes do not appear.
- - libcupsfilters: Fixed loading option/choice strings lists
- from driverless printers for PPD file generation. Especially
- proprietary media types appear correctly now.
- - libcupsfilters: Completed color space support in the PPD
- generator: Added DeviceGray/RGB/CMYK, default to 8 bit for
- SRGB and to 16 bit for AdobeRGB, avoid duplicate listings of
- the same color space.
-
-CHANGES IN V1.19.0
-
- - libcupsfilters: Let the PPD generator add the options "Print
- Optimization", "Print Rendering Intent" and "Print Scaling"
- if appropriate IPP attributes are found.
- - libcupsfilters: Let the PPD generator read out the maximum
- of info about color spaces and this way not only reliably
- the correct choices are added to the ColorModel option but
- also the maximum supported bit depth (8 or 16 bit) is used.
- - libcupsfilters: Overtaken new features from CUPS' PPD
- generator: Presets, Finishing Templates, and extraction of
- media sizes from "media-col-database"
- - libcupsfilters: Improvements on header of generated PPDs:
- use cups-filters version number, "drvless.ppd" PCFileName,
- APSupplies and cupsChargeInfoURI from CUPS.
- - libcupsfilters: Let the PPD generator use the IPP string
- tables in the translation files of CUPS 2.3.x or newer
- (English strings only). Let all options in the PPD have
- human-readable option and choice names. In case of CUPS
- 2.2.x or older (or if the CUPS translation are missing) we
- fall back to internal tables.
- - cups-browsed: Improved debug output when checking IPP
- attributes of IPP printers.
- - .gitignore: Ignore also core files.
- - cups-browsed: Support use of PPD files generated by CUPS for
- IPP Printers. Works only if the the local queue created by
- cups-browsed replaces a temporary queue from CUPS.
- Configurable via "UseCUPSGeneratedPPDs" directive in
- cups-browsed.conf.
-
-CHANGES IN V1.18.0
-
- - braille: Add support for page-ranges option. Thanks to
- Samuel Thibault for this patch (Pull request #12).
- - braille: Fix supporting docx and LO file names with
- spaces. Thanks to Samuel Thibault for this patch (Pull
- request #11).
- - .gitignore: Updated and cleaned up.
- - Build system: Make sure that "make dist" always includes all
- files of the repository, plus the files generated by
- ./autogen.sh, independent of the system configuration and
- the used ./configure options.
- - pdftoijs, pdftoopvp: Build pdftoijs and pdftoopvp only on
- demand (via "--enable-ijs" and "--enable-opvp" on the
- ./configure command line). There are actually no known
- printer drivers using these filters. If no one complains
- about the missing filters they will get completely removed.
- - Build system: Set default path for pdftops to
- /usr/bin/pdftops also for cross-compiling (Bug #1417).
- - cups-browsed: Set "printer-location" as an attribute and not
- as an option when creating/updating a CUPS queue (Bug
- #1413).
- - braille: Fix handling non-printable characters in BRF
- files. Thanks to Samuel Thibault for this patch.
- - braille: Fix printing backslashes in BRF files. Thanks to
- Samuel Thibault for this patch.
- - braille: use application/vnd.cups-brf instead of
- text/vnd.cups-brf. Thanks to Samuel Thibault for this patch.
- - braille: Make sure liblouis emits pure BRF output. Thanks to
- Samuel Thibault for this patch.
- - braille: Spaces at the head of lines were not getting
- embossed, because bash would eat them in the read
- command. IFS allows to avoid the issue. Thanks to Samuel
- Thibault for this patch.
- - gstoraster: Emit proper error message if Ghostscript is
- missing. Thanks to Peter De Wachter (pdewacht at gmail dot
- com) for the patch (Bug #1415).
- - braille: Old bash does not like quotes, like in '$(("123" +
- 0))'. Removed unneeded quotes. Thanks to Samuel Thibault for
- this patch.
- - braille: Index V5 embossers are compatible with the V4
- protocol so we do not need driver changes, we just need to
- advertise the support. Thanks to Samuel Thibault for this
- patch.
-
-CHANGES IN V1.17.9
-
- - cups-browsed: Applying option defaults from the
- DefaultOptions directive in cups-browsed.conf got
- lost. Re-introduced it (Bug #1414).
- - cups-browsed: Get printer-location field from remote
- printers. Thanks to Marek Kasik for the patch (Bug #1413).
-
-CHANGES IN V1.17.8
-
- - foomatic-rip: Change execution of renderer thread to fail
- whenever any of its individual sub-comands fails. Thanks to
- LUUM (luum at chromium dot org) for the patch (Bug #1412).
- - foomatic-rip: Parent process now ignores SIGPIPE calls from
- upstream/downstream CUPS filters, per
- https://www.cups.org/doc/api-filter.html, while correctly
- noting child process failures and exiting
- accordingly. Thanks to LUUM (luum at chromium dot org) for
- the patch (Bug #1412).
- - Build system: Fixed typo which broke the
- "--enable-gs-ps2write" ./configure command line option (Bug
- #1410).
-
-CHANGES IN V1.17.7
-
- - braille: Add a mirror option for graphical output. Thanks to
- Samuel Thibault for this patch.
- - braille: Rename the internal cups name of the Resize option
- to the standard well-known and well-documented fitplot
- option. Thanks to Samuel Thibault for this patch.
- - braille: Add support for margins in graphical mode,
- defaulting them to 15 points (a bit more than 5mm). Thanks
- to Samuel Thibault for this patch.
- - braille: Updated French translation. Thanks to Samuel
- Thibault for this patch.
- - braille: Add a PPD which generates UBRL output, i.e. Braille
- expressed in Unicode. This is not useful for actual
- embossers, but very convenient to check output to be
- embossed without wasting paper. Thanks to Samuel Thibault
- for this patch.
- - braille: Add virtual BRF backend for generating
- ready-to-emboss BRF files with CUPS, similarly to the
- cups-pdf backend. Thanks to Samuel Thibault for this patch.
- - braille: Some tools seem to emit true/false instead of
- True/False, so let us cope with it. Thanks to Samuel
- Thibault for this patch.
- - braille: "make uninstall" did not remove all the
- links. Thanks to Samuel Thibault for this patch.
- - braille: Add support for embossing MusicXML files, through
- the FreeDots transcriptor. Thanks to Samuel Thibault for
- this patch.
- - braille: Add proper support for hardware margins on braille
- embossers. Thanks to Samuel Thibault for this patch.
- - braille: Fix the disabling of the text margins in Index
- graphics mode. Thanks to Samuel Thibault for this patch.
- - braille: Support for direct, structured embossing of XML and
- XML-based file formats (like odt, docx, ...). Thanks to
- Samuel Thibault for this patch.
-
-CHANGES IN V1.17.6
-
- - braille: Embossers can only emboss integer numbers of 2x4
- cells. Thanks to Samuel Thibault for this patch.
- - braille: In Index graphical mode we need to disable the text
- margins, since they come in earlier on the way to
- there. Thanks to Samuel Thibault for this patch.
- - braille: Also, we should always add a 1.6mm margin for
- taking into account the width of dots. Thanks to Samuel
- Thibault for this patch.
-
-CHANGES IN V1.17.5
-
- - libcupsfilters: In the PPD generator for driverless printing
- renamed the "print-quality" option back to
- "cupsPrintQuality" as the support for this option got fixed
- in CUPS (CUPS issue #5090).
- - braille: Improvements on the braille support for bitmap
- images: Moves the graphical dot distance option to the image
- conversion group, add an option to avoid image resize, and
- make the rotation option easier by proposing to just fit
- paper instead of fitting portrait or landscape. Thanks to
- Samuel Thibault for this patch.
- - braille: Support for embossing vector images as braille.
- Thanks to Samuel Thibault for this patch.
- - braille: Fix liblouis1.defs installation. Thanks to Samuel
- Thibault for this fix.
-
-CHANGES IN V1.17.4
-
- - pdftopdf: If the input PDF file contains an interactive
- form, flatten it to static PDF so that further manipulation,
- like scaling, number-up, ... do not let the filled for
- content getting lost. This is implemented by using the
- pdftocairo utility of Poppler and if this fails Ghostscript
- (9.22 or later recommended). This will probably replaced by
- a QPDF-based solution later. Thanks to Tobias Hoffmann for
- the QPDF-based detection of PDF forms (Bug #1315, Ubuntu bug
- #1564249).
-
-CHANGES IN V1.17.3
-
- - bannertopdf: Make it working also with Poppler 0.58.0 and
- newer (Bug #1408).
- - gstoraster, pdftops, foomatic-rip: Added "-dShowAcroForm" to
- all Ghostscript command lines where the input data format
- can be PDF. With this and the fix of Ghostscript bug
- #698461 most filled PDF forms should be rendered correctly
- by Ghostscript now.
- - libcupsfilters: Do not check maximum resolutions of
- raster-based PDLs, as implementation was incorrect and
- reliability of PDLs is more important than maximum
- resolution.
-
-CHANGES IN V1.17.2
-
- - rastertopdf: Fixed outstanding bug in PCLm with JPEG (DCT)
- compression. Now PCLm support is completely working.
-
-CHANGES IN V1.17.1
-
- - libcupsfilters: Added direct PNG printing to the PPD
- generator, the one of CUPS has it, too.
- - libcupsfilters: In the PPD file generator renamed the option
- "cupsPrintQuality" into the IPP name "print-quality" as CUPS
- does not update the "print-quality=4" entry in the filter
- command line based on the setting of "cupsPrintQuality"
- (CUPS issue #5090).
- - libcupsfilters: Completely redone the way how to determine
- the resolutions to use for the default resolution and print
- quality option in the PPDs generated for IPP
- printers. Resolution lists from IPP attributes are now read
- into sorted, duplicate-free lists with wrong resolutions
- removed or fixed. Resolutions actually used are the common
- ones between the supported PDLs, PDls with inferior maximum
- resolution or with broken resolution list are skipped
- (Debian bug #868360, Ubuntu bug #1712019, CUPS issue #5088,
- CUPS issue #5091).
- - rastertopdf: Prefer RLE compression instead of Flate as
- there are HP printers where Flate is buggy.
- - Build system: Fixed help mesage for "--enable-driverless"
- configure option (Bug #1405).
-
-CHANGES IN V1.17.0
-
- - rastertopdf, rastertopclm, driverless, cups-browsed,
- libcupsfilters: Added support for the PCLm output format for
- driverless printing on printers using Wi-Fi Direct and other
- driverless printing standards.
- printers. This is the Google Summer of Code 2017 project of
- Sahil Arora (sahilarora dot 535 at gmail dot com). Thank you
- very much for your great work! The PCLm support requires
- QPDF 7.0.0 or later.
-
-CHANGES IN V1.16.4
-
- - Build system: Switched over to C11 standard with GNU
- extensions (-std=gnu11).
- - Build system: Removed -pedantic flag as it is only needed
- for compatibility with commercial compilers like the ones of
- Windows (and we use GNU extensions anyway).
- - libfontembed, texttopdf: reverted removal of anonymous
- union.
-
-CHANGES IN V1.16.3
-
- - libfontembed: Reverted unneeded soname change.
-
-CHANGES IN V1.16.2
-
- - README: Minimum CUPS requirement of cups-filters is CUPS
- 1.4.x. It does not build with earlier CUPS versions (Bug
- #993).
- - driverless, foomatic-rip: Create relative symbolic links.
- - All C/C++ files: Silenced all compiler warnings, at least
- the ones appearing when building on Ubuntu Linux 17.10 with
- GCC 7.1.0.
- - README: Updated the introduction section to reflect the
- current functionality of cups-filters, and the build
- requirements for the Poppler-based filters (C++11: Bug
- #1404, Build configuration of Poppler: Bug #1257). Thanks to
- Roland Hieber (r dot hieber at pengutronix dot de) to find
- out about this.
- - pdftoopvp, bannertopdf, pdftoraster: Build with C++11
- standard as some features of this standard are needed by
- these filters (or by Poppler). Thanks to Roland Hieber (r
- dot hieber at pengutronix dot de) for the patch (Bug #1404).
-
-CHANGES IN V1.16.1
-
- - cups-browsed: Make timeouts for HTTP access to the local
- CUPS daemon and remote IPP printers configurable. Thanks to
- Cedric Dufour (cedric dot dufour at idiap dot ch) for the
- patch (Bug #1387, Debian bug #852436).
- - texttopdf: Allow bold and underline formatting to be used
- together when using "prettyprint". Thanks to Michael Moran
- (vampm at comcast dot net) for the patch.
- - texttopdf: Allow to alter margins, and chars/lines per Inch
- when using "prettyprint". Thanks to Michael Moran (vampm at
- comcast dot net) for the patch.
- - texttopdf: When "prettyprint" is used, do not drop out of
- C/shell comment mode too early. Thanks to Michael Moran
- (vampm at comcast dot net) for the patch.
- - cups-browsed: Additional NULL checks for description and
- location.
- - cups-browsed: Fixed crash which happens when using
- BrowsePoll (Debian bug #723835).
-
-CHANGES IN V1.16.0
-
- - cups-browsed: Let elements in arrays get stacked up in the
- order they are added, before, they were in the order how
- they are positioned in memory. This especially led to a
- random order of printer cluster definitions and of
- command-line-supplied configuration options.
- - cups-browsed: On shutdown not all locally created queues got
- deleted.
- - cups-browsed: Added support for manual definition of
- load-balancing printer clusters via the "Cluster" directive
- in cups-browsed.conf.
-
-CHANGES IN V1.15.0
-
- - cups-browsed: Removed the function to compare printer entries
- for sorting the printer entry list. This led to corruption
- of the list and so to crashes.
- - cups-browsed: Fixed crashes when many printers (especially
- all printers of a load-balanced cluster) are removed at once.
- - cups-browsed: Log the full list of handled remote printers
- whenever one is added or removed.
- - cups-browsed: Renamed the handle_cups_queues() function to
- update_cups_queues() to better reflect what it is doing.
- - cups-browsed: When clustering remote CUPS printers together
- do not call them duplicates but slaves asigned to a master.
- - cups-browsed: Log the error if the network interface name of
- a DNS-SD event could not be determined.
- - cups-browsed: Simplified printer entry removal procedure.
- - cups-browsed: Log memeber printer list of a printer cluster
- (implicit class) when a member printer is added or removed.
- - cups-browsed: Removed superfluous (and not correctly
- working) duplicate counter from the remote printer entry
- data structure.
- - cups-browsed: Add "AutoClustering" directive to
- cups-browsed.conf to turn on and off automatically
- clustering equally named local print queues which point to
- remote CUPS printers. When automatic clustering is turned
- off, queue name clashes are prevented by adding "@<server
- name>" to local queue names based on the remote queue name
- or on make and model.
- - cups-browsed: Skip callback functions and the CUPS queue
- creation/update/removal loop when cups-browsed is terminated
- by a SIGTERM signal. This avoids hanging on shutdown. Thanks
- to Edgar Fuss (ef at math dot uni-bonn dot de, Bug #1402).
- - libcupsfilters: Added some fallbacks for incorrect
- resolution IPP attributes on IPP network printers (Debian
- bug #868360).
- - pdftoopvp: Added missing "#include <math.h>" needed for
- cross-compiling for arm-v7a-linux-gnueabi (Bug #1232).
- - cups-browsed: Prevent the creation of two remote printer
- entries for two IPP network printers or an IPP network
- printer and a remote CUPS printer with the same local queue
- name. This could easily happen with make/model-based naming.
- - cups-browsed: Added the possibility to optionally not
- create local queues for remote printers for which CUPS
- (from 2.2.x on) auto-creates queues by itself (DNS-SD
- advertised driverless printers).
- - cups-browsed: Removed repeated code for clean-up when
- generate_local_queue() function fails.
- - cups-browsed: Take care of CUPS' temporary queues. Do not
- consider them when checking whether a queue with the same
- name as the one we are creating already exists and make
- temporary queues permanent (or remove them) before
- overwriting them with our local queue.
- - cups-browsed: Make the naming scheme for locally created
- print queue configurable, especially allow for naming based
- on the DNS-SD service name (now default) as this is the same
- scheme as CUPS uses for its temporary queues. This way we
- prevent CUPS creating temporary queues when cups-browsed is
- already creating a queue.
- - cups-browsed: Do not add "APRemoteQueueID" keyword to the
- local queue's PPD file if the queue is for an IPP network
- printer.
- - cups-browsed: Skip multiple browse entries for the same
- printer with interface alias addresses. Thanks to Edgar
- Fuss (ef at math dot uni-bonn dot de, Bug #1399).
- - cups-browsed: Improved support for Description (Info) and
- Location fields of remote CUPS queues. Thanks to Edgar Fuss
- (ef at math dot uni-bonn dot de, Bug #1398).
- - cups-browsed: Renamed variable names for better code
- readability. Thanks to Edgar Fuss (ef at math dot uni-bonn
- dot de, Bug #1398).
- - cups-browsed: Additional NULL checks in the
- create_local_queue() function. Thanks to Edgar Fuss (ef at
- math dot uni-bonn dot de, Bug #1398).
-
-CHANGES IN V1.14.1
-
- - cups-browsed: Do correct removal of printer entry handling
- duplicates correctly also when a legacy CUPS-broadcasted
- printer disappears or a printer remaining from the last
- session does not appear again.
- - cups-browsed: Use getline() instead of fgets() to read saved
- option settings. This is less crash-prone (Ubuntu bug
- #1658833).
- - cups-browsed: Improved error logging when saving option
- settings.
- - cups-browsed: Added NULL checks for generate_local_queue()
- and create_local_queue() functions.
- - cups-browsed: When accessing local CUPS queues use always
- the correct port of the CUPS daemon we are attached to.
- - cups-browsed: Check whether a connection to the local CUPS
- daemon actually happened before using it (Ubuntu bug
- #1644049).
- - cups-browsed: Set unused fields of printer record to NULL
- when tranfering data from the record of a duplicate printer
- to the record of a disappeared one.
- - cups-browsed: Simplify removal of all queues on shutdown or
- stop of Avahi.
- - cups-browsed: When creating a record for a discovered
- printer set it all zero before filling it in, to assure
- that no field is in an undefined state.
- - cups-browsed: All functions which are called via Glib
- functions or otherwise event-triggered log now in which
- thread they are running. This way one can see whether
- problems can be caused by concurrent access to global
- resources.
- - cups-browsed: Do not check whether the DNS-SD event is from
- the local machine in the browse_callback() function. We
- cannot check the port here.
- - cups-browsed: Added more NULL checks to Avahi callback
- functions.
- - cups-browsed: Added NULL check to avoid crashes in the Avahi
- resolver callback (Ubuntu bug #1696967).
- - libcupsfilters: Let PPD generator do case-insensitive
- comparisons for PWG Raster color spaces, as some printers
- (Epson) do not use the standard-conforming all-lowercase
- form for them (CUPS Issue #4998).
-
-CHANGES IN V1.14.0
-
- - cups-browsed: When a printer is discovered via DNS-SD on the
- "lo" (loopback) interface the printer is not reliably
- accessible through the reported host name (which is the
- network host name of the local machine). Until this problem
- is fixed in Avahi, we create queues for such printers with a
- URI based on the IP address. This is a workaround until
- Avahi fully supports the "lo" interface.
- - cups-browsed: Added new setting "LocalOnly" for the
- CreateIPPPrinterQueues in cups-browsed.conf. With this new
- setting (which is the default from now on) only for local
- printers made available as IPP printers (like IPP-over-USB
- printers with ippusbxd) queues are auto-created. With this
- we can follow the common standard of distributions where USB
- printers are automatically set up and network printers not.
- - cups-browsed: Fixes and improvements in comments and debug
- messages: 1. Bonjour -> DNS-SD; 2. When a remote CUPS class
- is discovered, tell that it is a class; 3. Show network
- interface and IPv4/IPv6 when a DNS-Sd service appears or
- disappears.
- - cups-browsed: Added ./configure script option
- "--enable-auto-setup-driverless" to let cups-browsed
- automatically set up IPP network printers by default.
-
-CHANGES IN V1.13.5
-
- - foomatic-rip: When called via the utility cupsfilter from
- CUPS, foomatic-rip was not able to read the PPD file with
- the file name supplied as environment variable PPD (Bug
- #1388).
- - driverless: Improved error message output.
- - libcupsfilters: Fixed error handling of the PPD file
- generator for driverless printing, so that callers get
- decent error messages.
- - libcupsfilters: Do not generate a PPD file where the only
- output data format is JPEG, as JPEG does not support
- multi-page documents.
- - libcupsfilters: Let PPD generator skip broken page size
- records and add warnings for debugging to the PPD.
- - libcupsfilters: Updated PPD generator to match with the
- current GIT state of the one of CUPS.
- - braille: Automatically select a table according to the
- current locale.
- - braille: Update for liblouis table list.
- - braille: Added support for text margins.
- - cups-browsed: When creating a local queue for a remote CUPS
- printer, add the line '*APRemoteQueueID: ""' to the PPD file
- so that CUPS sets the CUPS_PRINTER_REMOTE bit for the
- printer type of the local queue (Bug #1386).
-
-CHANGES IN V1.13.4
-
- - libcupsfilters: Let PPD generator for driverless printing
- not error out when there is no urf-supported or
- pwg-raster-document-resolution-supported IPP attribute,
- simply accept the default resolution also from the
- printer-resolution-default attribute or set a default value
- of 300 dpi to get a working PPD file.
- - cups-browsed: Do not use deprecated names for IPP status
- constants
- - cups-browsed: Corrected determination whether an IPP status
- is an error, to avoid "Unable to create/modify CUPS queue
- (Success)" and infinite repetition of a succeeded operation
- (Debian bug #852436).
-
-CHANGES IN V1.13.3
-
- - libcupsfilters: When auto-generating PPD files added support
- for passing through JPEG input to printers which understand
- JPEG. This is also done in CUPS-generated PPDs (Debian bug
- #851499).
- - libcupsfilters: Added the "output-bin" option support from
- CUPS' PPD generator to our PPD generator (CUPS Issue #4938).
- - cups-browsed: Make support for printers with IPv6 IP address
- work. Both link-local and regular addresses work.
-
-CHANGES IN V1.13.2
-
- - cupsfilters.drv: Corrected cupsFilter entry for the "Generic
- IPP Everywhere Printer".
- - driverless: Fixes on the man page (Debian bug #849075).
- - driverless: Do not error-exit (non-zero status) when run by
- CUPS as backend or PPD generator when no driverless printer
- is found or Avahi not running. When run from thr command
- line, exit status is the same as of ippfind.
- - imagetoraster: Removed (incomplete) PWG Raster support. For
- PWG Raster output we let the rastertopwg filter from CUPS do
- the finalization (mainly adding white pixels at the borders
- to get a full-page bitmap).
- - imagetoraster: Fixed several bugs in the calculation of the
- page geometry (Debian bug #849380).
- - libcupsfilters: If the IPP-polled printer has the
- "sides-supported" attribute, determine the need of a
- "Duplex" option solely whether the attribute has a
- "two-sided-long-edge" choice and ignore the "duplex"
- parameter of the ppdCreateFromIPP() function call. This lets
- the more precise information coming from the IPP query
- always be preferred against information from the Bonjour
- record.
- - driverless: When listing printers let the device ID contain
- "AppleRaster" (for Apple Raster printers) and "PWGRaster"
- (for IPP Everywhere printers) in the "CMD" field.
- - driverless: Added "-T 3" to the ippfind command line. This
- makes ippfind search the Bonjour broadcasts for up to 3
- seconds when searching for IPP printers, raising the
- reliability in finding all of them (Debian bug #848712).
-
-CHANGES IN V1.13.1
-
- - cups-browsed: Avoid erroring out when restarting after a
- crash (with generated queues not deleted due to the crash)
- and the configuration option
- CreateRemoteCUPSPrinterQueues=No being set.
- - cups-browsed: If CUPS is stopped while cups-browsed is
- running and there are queue for IPP network printers (not
- remote CUPS queues) on restart of CUPS the still existing
- local CUPS queue is not correctly re-connected with
- cups-browsed and therefore gets removed after a
- timeout. This should be fixed after a clean-up of
- re-connecting with remaining queues from a previous session
- (Debian bug #848223).
- - cups-browsed: Generated queues did not get removed on
- shutdown (Debian bug #848167).
- - libcupsfilters: Let PPD generator for driverless printing
- suppress page sizes which the printer reports more than
- once (CUPS Issue #4933).
- - driverless, libcupsfilters: Make "driverless list" output
- and output of driverless as CUPS backend in discovery mode
- add the word "driverless" to its output, to make it easier
- to set up driverless printers with printer setup tools.
- Made the NickName of the generated PPDs also match with the
- "driverless list" output.
-
-CHANGES IN V1.13.0
-
- - cups-browsed: Use the httpGetAddr() only with CUPS 2.0.x or
- newer, as older CUPS versions do not provide it (Bug #1381).
- - cups-browsed: Minor corrections in the handling of the data
- records of the discovered printers.
- - rastertopdf, urftopdf: As with libcupsimage from CUPS 2.2.2
- on rastertopdf also understands Apple Raster and much better
- than urftopdf does, use rastertopdf for Apple Raster
- (image/urf) input files then. Also allow for manually
- choosing by the ./configure command line.
- - driverless: Added a CUPS backend mode to the driverless
- utility. Running as a CUPS backend in discovery mode it
- lists the IPP URIs of the suitable printers in printer setup
- tools and in "lpinfo -v", as conneting via IPP is required
- for driverless printing.
-
-CHANGES IN V1.12.0
-
- - cups-browsed: Added new "CreateRemoteCUPSPrinterQueues"
- directive to cups-browsed.conf, which allows to decide
- whether to auto-create local print queues for shared CUPS
- queues on remote machines. This way one can also set up
- servers which only create queues for IPP network printers.
- - driverless: Added new /usr/lib/cups/driver/driverless
- utility to make CUPS auto-generate PPD files for printers
- designed for driverless use (IPP Everywhere, Apple Raster)
- when they are set up with a printer setup tool. This gives
- transparency to set up these printers with legacy printer
- setup tools. This utility is also linked to /ustr/bin to
- manually generate PPDs via command line.
- - libcupsfilters, cups-browsed: Moved the PPD generator for
- IPP network printers from cups-browsed to libcupsfilters, so
- that it can also be used by other utilities.
- - cups-browsed: When auto-generating a PPD set the cost values
- in the filter lines to give the highest priority to PDF,
- then PWG Raster, Apple Raster, PCL-XL, PostScript, PCL 5c/e.
- - cups-browsed: Synced the PPD generator with the one of CUPS,
- giving the best possible support for IPP Everywhere and
- AirPrint printers. Especially support for more media types
- and for finishing units got added. Also support for more
- different ways to represent the printer capabilities via
- IPP attributes got added.
- - cups-browsed: Added support for auto setup of IPP printers
- understanding the Apple Raster input data format (.urf, on
- AirPrint printers), only if CUPS 2.2.2 is used, which can
- generate this format via its rastertopwg filter.
- - cups-browsed: Added new "NewIPPPrinterQueuesShared"
- directive to cups-browsed.conf, which allows to decide
- whether the auto-created local print queue for a newly
- discovered IPP network printer will be shared or not. For
- printers discovered earlier, cups-browsed remembers the
- previous setting.
- - cups-browsed: If a user changes the printer-is-shared bit of
- an auto-created print queue for an IPP network printer (not
- for a remote CUPS queue), record this fact and recover the
- change when creating this queue in the next session.
- - cups-browsed: For automatic creation of print queues for IPP
- network printers also allow only creating queues for IPP
- Everywhere printers, only for Apple Raster printers, or for
- both printer types designed for driverless printing and not
- only for all suitable printers, configurable via the
- CreateIPPPrinterQueues directive in cups-browsed.conf.
-
-CHANGES IN V1.11.6
-
- - pdftops: Do not default to simply "pdftops" when calling the
- Poppler pdftops utility, as the $PATH of CUPS when running
- filters/backends starts with /usr/lib/cups/filter/ and then
- pdftops would call itself (Bug #1380).
-
-CHANGES IN V1.11.5
-
- - cups-browsed: Fixed several typos in the documentation (Bug
- #1378).
- - gstoraster, mupdftoraster, pdftops, sys5ippprinter: Use
- execvp() and execvpe() to call programs so that the $PATH
- environment variable gets used to find the programs (Bug
- #1378).
- - build system: Several fixes, especially to make it work when
- cross-compiling or using a build server (Bug #1378).
- - cups-browsed: Silenced a warning.
- - cups-browsed: For remote CUPS queues with a dot in their
- name no local queue got created (Bug #1379).
- - pdftopdf: Do the page logging also for IPP Everywhere
- printers which use the PWG Raster data format as the
- ...toraster filters being the last filter then do not log.
- - gstoraster, pdftoraster: Let filters generate PWG Raster if
- the environment variable FINAL_CONTENT_TYPE is set to
- image/pwg-raster, make sure full-page bitmaps are generated
- in PWG_raster mode, and added mime conversion rules for
- direct PWG Raster output.
- - cups-browsed: Corrected checking of the PDLs of an IPP network
- printer. Now PCL 5c/e printers (not HP inkjets) should get
- recognized correctly.
- - texttopdf: Added missing NULL check to avoid a segfault when
- texttopdf does not find a suitable (monospace TTF) font.
- - foomatic-rip: Replace old manpage macro calls from
- foomatic-filters 3.0.2-20050114.
- - cups-browsed: Allow changing BrowseInterval and
- BrowseTimeout via cups-browsed.conf, as it was formerly with
- CUPS (Debian bug #794655).
- - pdftopdf: Count the actual output pages also if the
- number-up option is not used, to correctly find out whether
- we have an even or odd number of pages, even if the
- page-ranges option is used. This is needed to correctly
- decide whether for duplex printing a blank page has to be
- added (Bug #1377).
-
-CHANGES IN V1.11.4
-
- - gstoraster: Allow Ghostscript to use the center-of-pixel
- method instead of the PostScript-standard any-part-of-pixel
- method when rendering filled paths. This improves the
- graphics output quality of low-resolution printers like
- label printers, for example to assure readability of bar
- codes (Bug #1373).
- - cups-browsed: Fixes to avoid unneeded calls of
- handle_cups_queues() and even infinite loops (Possible fix
- for bug #1376). Also make sure that queues left over from
- the previous cups-browsed session are integrated correctly.
-
-CHANGES IN V1.11.3
-
- - cups-browsed: If a queue is not only discovered via Bonjour
- but also via legacy CUPS or LDAP, prefer the Bonjour record
- as it provides more information and there is also a defined
- cancellation broadcast.
- - cups-browsed: Let PPD options saved in the last session also
- get applied to generated PPDs for IPP network printers.
- - cups-browsed: Make sure that saved PPD options do not get
- lost if for some reason the PPD file cannot be loaded in a
- new cups-browsed session (or the loaded PPD file is
- different). This is done by holding a copy of the settings
- in the remote printer data structure.
- - cups-browsed: When saving option settings, remove
- backslashes added when the settings are read out via IPP
- request. Otherwise the backslashes would double with each
- session of cups-browsed.
- - implicitclass: Do not let the job get immediately retried on
- failure to send it out to the remote CUPS printer. By
- repeating to send the job to an unavailable server so
- quickly, cups-browsed gets bombed with requests and hangs on
- shutdown.
- - cups-browsed: Shortened timeouts of HTTP connections and IPP
- requests to 3 seconds amd of IPP requests to remote CUPS
- servers to 2 seconds. For local IPP requests always use the
- connection once created via http_connect_local(). Also call
- g_main_context_wakeup(NULL) after each
- g_main_loop_quit(gmainloop) call. These measures should
- reduce long hangs of cups-browsed on shutdown when a CUPS
- server got unavailable.
- - cups-browsed: Do not mark remote printers discovered via
- legacy CUPS broadcasts as disappeared right from the
- beginning to implement the browse timeout. Instead manage
- their expiring by introducing a flag which marks them as
- CUPS legacy printers. Printers with disappeared status are
- considered invalid in some situations, especially when
- clusterin equally-named remote printers (Bug #1374).
- - cups-browsed: When we have remote CUPS printers, we use the
- implicitclass backend and a local copy of the remote PPD
- file already if we have only a single remote printer with
- this queue name. This simplifies the management of remote
- CUPS printers and also we do not hassle with using a remote
- PPD file. Now one can change PPD option defaults with
- printer setup tools or the lpadmin command and they get
- preserved in the next cups-browsed sessions.
- - if we are using the implicitclass backend CUPS does not make
- the server's PPD file available on the client any more. To
- fix this, we download the PPD file when creating an
- implictclass:... queue and apply it to the queue. This way
- the options of the printer(s) are always available for
- enumeration, especially in print dialogs (Bug #1372). We
- modify the local copy setting any options saved from the
- previous session and inhibiting local execution of filters
- (as the driver for the remote printer is not necessarily
- available locally).
- - cups-browsed: Added flag to inhibit auto-backup of option
- settings by the on_printer_modified() notification handler
- during print queue setup and removal.
- - cups-browsed: Let the printer_record() function always
- return the master record for the printer name and not an
- arbitrary duplicate.
- - cups-browsed: Fixes in the functionality for saving option
- settings: Make sure to not save the same option twice with
- different values, do not save the "printer-is-shared" option
- (errors out when re-applying option in the next session).
- - cups-browsed: Treat discovered printers correctly also if
- they use a non-standard port, even if several CUPS daemons
- are running on the same server but on different ports. This
- also improves the support of a sandboxed printing stack.
- - cups-browsed: Close http connections opened for polling
- properties of IPP network printers, to fix a possible memory
- leak.
- - cups-browsed: Cleaned up HTTP access to local and remote
- CUPS servers and IPP printers, to assure that the local CUPS
- daemon is always accessed the same (user-defined) way
- (domain socket/localhost:port). This especially prevents
- cups-browwsed hanging on shutdown (Debian bug #832637).
- - cups-browsed: Fixed clustering equally-named queues of
- different remote servers, to assure to have one master
- referencing to all duplicates and not a daisy chain of
- duplicate references.
-
-CHANGES IN V1.11.2
-
- - cups-browsed: Allow turning off the use of CUPS' domain
- socket via cups-browsed.conf.
- - foomatic-rip: When run as regular CUPS filter use preferably
- /etc/cups/foomatic-rip.conf (or whereever the CUPS
- configuration files reside, according to the CUPS_SERVERROOT
- environment variable) as configuration file. This way we can
- more easily run the printing stack in a sandbox.
- - foomatic-rip: When run as regular CUPS filter, read the PPD
- through CUPS and get the print queue name by environment
- variable.
- - bannertopdf, foomatic-rip, gstoraster, mupdftoraster,
- pdftoopvp, pdftoraster: Do not use build-time hard-coded
- paths, but always the paths from the environment variables
- which CUPS sets when calling its filters. This is needed to
- run the printing stack in a sandbox.
-
-CHANGES IN V1.11.1
-
- - mupdftoraster: Lowered the priority (raised the cost value)
- in the cupsfilters-mupdf.convs file so that in a full
- cups-filters installation MuPDF is not prioritized.
-
-CHANGES IN V1.11.0
-
- - pdftops: Added support for MuPDF as PDF renderer. MuPDF can
- be selected by the "pdftops-renderer=mupdf" option.
- - rastertops: Removed unneeded page logging.
- - rastertops: Fixed DSC comments, some were only preceded by
- a single '%' instead of a double "%%".
- - gstoraster, pdftops, foomatic-rip: Use -dNOMEDIAATTRS when
- calling Ghostscript. This way Ghostscript does not try to
- match media sizes with internal lists.
- - Build system: Allow building cups-filters without Poppler
- (--disable-poppler in ./configure command line) This skips
- the build of pdftoraster, bannertopdf, pdftoijs, and
- pdftoopvp and the installation of these filters and their
- auxiliary files. With this cups-filters can be easily
- installed on mobile/appliance systems with MuPDF as the only
- PDF interpreter.
- - mupdftoraster: Added filter to support MuPDF as PDF
- interpreter. MuPDF is a lightweight PDF interpreter
- especially interesting for mobile systems and
- appliances. Thanks to Pranjal Bhor for contributing this as
- part of his Google Summer of Code project.
- - gstoraster: Fix setting of width and height of the page in
- pixels when there is no Resolution option in the PPD.
- - cups-browsed, implicitclass: Avoid the use of files for the
- communication between cups-browsed and the load-balancing
- backend implicitclass. Instead of in a file, cups-brwsed
- stores the destination server name in an option (which CUPS
- saves in printers.conf) which the implicitclass backend
- reads via IPP. This not only makes it easier to run
- cups-filters in a sandbox, but it is also better in terms of
- system security.
- - cups-browsed: Allow configuring where the files produced by
- cups-browsed will get stored. This makes it easier to run
- cups-filters in a sandbox.
- - beh: Fixed printing multiple copies with beh (Ubuntu bug
- #1605514).
- - cups-browsed: Fixed several memory leaks, especially when
- using IPP requests and DNS-SD TXT record look-ups. Thanks to
- Ivo Straka for finding them with Valgrind and supplying
- patches to fix them (Bug #1365, Bug #1368, Ubuntu bug
- #1203276).
- - libcupsfilters: Added missing "#include <cups/ppd.h>" to
- make sure that the package builds on all systems (Bug
- #1366).
-
-CHANGES IN V1.10.0
-
- - texttotext: Added new filter for text-only printers written
- in C, to use the CUPS library to access the print queue's
- PPD file, with a lot of options to fit practically all
- printer models amd paper sizes, support for CUPS' page
- management options, and support for configuring the print
- queue and controlling the options by the PPD file. The PPD
- is now generated on-the-fly by cupsfilters.drv.
- - textonly: Removed the old script-based filter and its PPD
- for text-only printers.
- - rastertops: Added new filter to turn PWG Raster into
- PostScript, in preparation for MuPDF support. Thanks to
- Pranjal Bhor for contributing this as part of his Google
- Summer of Code project.
- - gstoraster, gstopxl, gstopdf, pstopdf: Integrated
- functionality of script-based filters pstopdf and gstopxl
- into gstoraster filter as script-based filters cannot access
- the print queue's PPD file with current CUPS due to change
- of PPD file permissions. To make gstoraster always produce
- the correct output format (CUPS/PWG Raster, PDF, PCL-XL) it
- is called via new wrapper scripts (gstopdf, gstopxl) which
- set an environment variable telling the format. The old
- filter scripts got removed.
- - imagetops, texttops: Do not use $0 in the wrapper scripts,
- when CUPS calls filters, it passes the queue name as $0, not
- path and name of the called filter.
- - cups-browsed: When creating local queues for discovered IPP
- network printers always create PPD files and if the
- information supplied by the printer via IPP is insufficient
- use information from the DNS-SD entry or default values
- suitable for most printers. Use System V interface scripts
- only on explicit request in cups-browsed.conf. This change
- is to address the fact that System V interface script
- support is removed from CUPS 2.2.x and later for security
- reasons.
- - pstopdf: Make the filter only get installed if Ghostscript is
- present and also moved its conversion rules into the
- cupsfilters-ghostscript.convs file.
- - cups-browsed: Fixed crash when trying to get debugg logging
- both to the terminal and into a file.
- - libcupsfilters: Fixed crash of pdftoraster when the color
- space is an RGB space (3 colors) with 1 bit color
- depth. Here we need to add one bit to the pixels (to get 4
- bits per pixel) to align the pixels with the bytes.
- - cups-browsed: From cups-browsed.service removed the unneeded
- "Wants=cups.service" as we have "Requires=cups.service"
- (Debian bug #827455, #827457).
- - foomatic-rip: Updated man page for removed page logging
- facility.
- - pdftops: Also added Dell to the list of manufacturers whose
- printers need Poppler's PostScript to work around their
- PostScript interpreter bugs (Debian bug #827040).
-
-CHANGES IN V1.9.0
-
- - foomatic-rip: Removed page logging via insertion of PostScript code.
- This works only with Ghostscript and PostScript input and even
- then it can break things or simply not work. We do the page logging
- for foomatic-rip in pdftopdf now, which is more universal and more
- reliable.
- - sys5ippprinter: Added page logging (to /var/log/cups/page_log)
- functionality.
- - pdftopdf: Added functionality for logging pages in the
- /var/log/cups/page_log file. Logging can also be forced or
- surpressed via command line (page-logging=on/off/auto) and
- page logging is also done for filters which should do but
- actually do not do: foomatic-rip, gstopxl, hpps (CUPS issue #4798,
- Ubuntu bug #1585380).
- - pdftopdf: Whitespace and indentation clean-up.
- - README: Removed the documentation of the old Poppler-based pdftopdf
- filter which is not included any more.
- - cups-browsed: Do not schedule failed operations for later repetition
- during shutdown.
- - cups-browsed: Added support for debug logging into a file (usually
- /var/log/cups/cups-browsed_log, to be activated via "-l" or
- "--logfile" option or via "DebugLogging file" option in
- cups-browsed.conf.
- - cups-browesd: Consistent use of debug_printf() in the LDAP support.
- - cups-browsed: Added "Requires=cups-service" to the
- cups-browsed.service file, so that systemd keeps CUPS running while
- shutting down cups-browsed on system shutdown (Ubuntu bug #1579905).
- - README: Extended pdftopdf's documentation.
- - README: Added documentation for the pdfAutorotate option in
- pdftopdf.
- - gstoraster: Treat status output of the waitpid() function properly,
- to avoid gstoraster exiting with zero status when Ghostscript
- exited with non-zero status or got terminated by a signal
- (Bug #1354).
- - README: Fixed typos. Thanks to Pranjal Bhor (bhor dot pranjal at
- gmail dot com) for the patch.
- - braille: Recognize application/vnd.cups-pdf-banner MIME type and
- read standard input directly instead of using /dev/stdin.
- - braille: Drop output of the "type" command when checking the
- presence of helper utilities.
- - braille: Do not send EOF twice to the braille embosser.
- - cups-browsed/sys5ippprinter: Fixed documentation about the allowed
- input formats for auto-created network printer queues using
- sys5ippprinter, also improved NEWS entry about renaming of
- sys5ippprinter (Debian bug #819665).
-
-CHANGES IN V1.8.3
-
- - cups-browsed: When creating or modifying a local print queue
- set the printer-is-shared bit to false in a separate IPP
- request as this operation errors on queues directly pointing
- to remote CUPS queues with the IPP backend. This way we can
- ignore the error and assure that all other settings are
- applied (Ubuntu bug #1560099).
- - Fixed pkg-config support so that $PKG_CONFIG gets used and
- cross compilation works (Bug #1347).
- - gstoraster: Put conversion rules for this filter into a
- separate file, so that they do not get installed when we
- build without Ghostscript support (Bug #1346).
- - Allow disabling dependencies on IJS (Bug #1345).
- - pdftops: Switch to Poppler as PDF renderer also for the
- Apple LaserWriter 12/640, to work around a bug in the
- printer's PostScript interpreter (Bug #1344).
-
-CHANGES IN V1.8.2
-
- - Allow disabling dependencies on Ghostscript and Foomatic
- (Bug #1342).
- - cups-browsed: Optionally generate also local queues pointing
- to remote raw queues. Usually only queues pointing to remote
- queues with PPD/driver are created (Debian bug #814020,
- Debian bug #756724).
-
-CHANGES IN V1.8.1
-
- - cups-browsed: Do not disable queues which still have jobs (and
- therefore cannot be removed) when avahi-daemon goes away, the
- print server is most probably still available and printing can
- be continued. Especially important on mobile devices where
- avahi-daemon is shut down when the print dialog is closed (and
- the job(s) still printing).
-
-CHANGES IN V1.8.0
-
- - COPYING: Replaced the COPYING file by a file in Debian format,
- derived from Debian's file but updated and corrected.
- - braille: Added info about additional packages needed for Braille
- printing to the README file.
- - braille: Let the Braille filters use lou_translate of
- liblouis if the more sophisticated file2brl of liblouisutdml
- is not installed. This is decided on at run time, so later
- installation of liblouisutdml will let the filters
- automatically switch to file2brl.
- - braille: Allow to build with Braille support also if
- liblouis is not installed at build time.
- - braille: Added checks for the presence of helper tools, to
- get clear messages in the CUPS error_log if something is
- missing.
- - Fixed copyright headers of files inherited from CUPS or
- derived from CUPS, pointing to COPYING as license info file,
- removing Apple exceptions, removing hints that a missing
- license info file can be found at www.cups.org, and removing
- "$Id" SVN file ID placeholders.
- - Updated COPYING file for missing implicitclass and beh
- backends.
-
-CHANGES IN V1.7.0
-
- - cups-browsed: Added possibility to trigger the auto shutdown
- by the queues of cups-browsed being without jobs. Before
- auto shutdown was only possible when all queues have gone
- away. This allows auto shutdown on mobile devices where
- avahi-daemon is also used for other things than printing.
-
-CHANGES IN V1.6.0
-
- - cups-browsed: Fixed use of CUPS domain socket, both
- detection during build process and permission check at
- runtime.
- - foomatic-rip: Fixed buffer overflow when reading environment
- variables CUPS_FONTPATH, CUPS_DATADIR, and GS_LIB (Bug
- #1336).
- - beh: Introduced beh, the Backend Error Handler, a wrapper
- backend to make handling of backend errors more
- configurable. This backend is a C re-write of the beh
- backend written in Perl which was part of the former
- foomatic-filters package. Several people asked for beh
- getting moved to cups-filters.
- - braille: Make image printing working also if ImageMagick
- generates formatted images without header.
- - braille: If the user does not select a Braille translation,
- let the embosser do the translation.
- - cups-browsed: Added version info to help screen and start-up
- in debug mode, call help screen also via "--version" option.
- - cups-browsed: Minor improvements in help screen and man
- page.
-
-CHANGES IN V1.5.0
-
- - cups-browsed: Allow use of an alternative configuration file
- via the "-c" command line option.
- - cups-browsed: Allow supplying configuration settings via the
- command line using the "-o" command line option.
- - cups-browsed: Command line help via the "-h" or "--help"
- command line option.
-
-CHANGES IN V1.4.0
-
- - foomatic-rip: SECURITY FIX: Also consider the semicolon
- (';') as an illegal shell escape character. Thanks to Adam
- Chester (adam dot chester at pentest dot co dot uk) for the
- hint (CVE-2015-8560).
- - brftoembosser, imagetobrf, imagetoubrl, imageubrltoindexv3,
- imageubrltoindexv4, textbrftoindexv3, textbrftoindexv4,
- texttobrf, braille.convs, braille.types, generic-brf.drv,
- indexv3.drv, indexv4.drv: Added support for Braille
- embossing via CUPS. Text and even images can now be sent to
- a Braille embosser like to a printer. Thanks to Samuel
- Thibault (samuel dot thibault at ens-lyon dot org) for this
- contribution.
-
-CHANGES IN V1.3.0
-
- - cups-browsed: Added new BrowseFilter directive in
- cups-browsed.conf. This directive allows filtering of the
- remote printers to be accepted on most properties/metadata
- supplied with the DNS-SD broadcasts. This allows, in
- addition to BrowseAllow/BrowseDeny/BrowseOrder, to reduce
- the amount of printers listed in print dialogs to a more
- useful amount.
- - cups-browsed: Added support for BrowseDeny and BrowseOrder
- directives in cups-browsed.conf.
- - cups-browsed: Let the BrowseAllow lines in cups-browsed.conf
- also apply to remote printers discovered via DNS-SD.
- - cups-browsed: Auto-create queues for PCL-5c/e printers but
- not for HP inkjet printers (which also advertise themselves
- as PCL printers).
- - cups-browsed, sys5ippprinter: Recognize PCL-5c/e printers
- not only by the application/vnd.hp-pcl MIME type but also by
- application/pcl and application/x-pcl.
-
-CHANGES IN V1.2.0
-
- - cups-browsed: When using IP-address-based device URIs via
- the "IPBasedDeviceURIs" directive in cups-browsed.conf, add
- two additional settings to restrict the used IP addresses to
- either only IPv4 addresses or only IPv6 addresses.
- - foomatic-rip: SECURITY FIX: Also consider the back tick
- ('`') as an illegal shell escape character. Thanks to Michal
- Kowalczyk from the Google Security Team for the hint
- (CVE-2015-8327).
-
-CHANGES IN V1.1.0
-
- - Version numbering scheme changed: Releases with feature
- addition/change have the minor number increased now, pure
- bug fix releases get the revision number increased, to make
- use of the minor number which stayed zero all the time.
- - cups-browsed: Added "DefaultOptions" directive to
- cups-browsed.conf to allow defining default option settings
- for local queues to be generated for newly appearing remote
- printers.
- - cups-browsed: Removed assert() calls which remained from
- copy and paste in the very beginning of the development of
- cups-browsed. assert() is only for use during debugging and
- should not be used in production code.
- - cups-browsed: Let option settings of a generated print queue
- be saved before taking the queue down so that when the remote
- printer appears again all user changes get restored, making
- user changes permanent on generated queues.
- - foomatic-rip: Fixed string length for shell path constant, to
- work also with systems having longer paths (Bug #1325)
- - cups-browsed: Added a mode in which IP-based device URIs
- for the generation of local print queues are used, for
- cases with problems in local host name resolution.
- - foomatic-rip: Use -dFirstPage=... and -dLastPage=... only
- if really needed (Bug #1324).
- - cups-browsed, implicitclass: Make the load-balancing
- configurable so that one can select whether the jobs get
- queued up locally like in a CUPS class or whether they get
- immediately distributed to the remote servers letting them
- queue up there.
-
-CHANGES IN V1.0.76
-
- - cups-browsed: Make build also working with BSD make (Bug
- #1310).
- - cups-browsed, implicitclass: Let the load-balancing queue up
- the jobs in the local (generated) queue until a free (idle,
- enabled, and accepting jobs) remote queue is found (check
- every 5 sec if no free queue available). This gives a more
- even distribution of the work amongst the servers and
- protects against the case that a bunch of jobs gets
- inaccessible or lost if one of the servers fails.
- - cups-browsed: Let the load-balancing also check whether the
- destination queue is actually accepting jobs.
- - cups-browsed: If a generated queue is not removed on
- shutdown of cups-browsed due to remaining jobs in it,
- re-enable it in the next cups-browsed session even if it was
- disabled by something other than cups-browsed.
- - implicitclass: Clean up debug and error messages.
- - implicitclass: Fix exit codes for immediate retry of jobs.
- - cups-browsed: Make absence of CUPS notifications via D-Bus
- non-fatal and fall back to the old behavior of cups-browsed
- (fail-over instead of load balancing for equally-named
- remote queues, do not remove generated queue if it is
- default instead of default printer management). This solves
- problems of CUPS and/or cups-browsed built without D-Bus
- support or absence of D-Bus on the system (Bug #1316).
- - cups-browsed: Do not use g_warning() function, sneaked in by
- copy and paste of CUPS subscription functions.
-
-CHANGES IN V1.0.75
-
- - texttopdf: Really support BoldItalic (original texttops just maps
- BoldItalic to Bold).
- - texttopdf: Fixed segfault when outputting BoldItalic (Bug #1314).
-
-CHANGES IN V1.0.74
-
- - cups-browsed: Added NULL check when getting the notification of
- a printer starting to process a job and checking whether this
- printer is created by cups-browsed with the implicitclass:
- backend (Ubuntu bug #1488524).
- - backends: Include unistd.h and fcntl.h in backend-private.h for
- all platforms, not only Linux, so that the backends build also
- on non-Linux platforms (Bug #1308).
- - cups-browsed: Do not schedule printers for update when they are
- already marked as disappeared.
- - cups-browsed: Added sanity checks when saving the default printer
- selection in a file.
- - cups-browsed, implicitclass: If remote queues disappear or
- cups-browsed shuts down and a cups-browsed-generated queue still
- has jobs and needs to be kept therefore, disable it and re-enable
- it when cups-browsed starts again and/or the remote queue(s) re-
- appear(s). This avoids repeated retries of the jobs while the
- remote server is not available, causing unneeded system load and
- battery consumption.
- - cups-browsed: After polling info from remote CUPS servers to find
- the best destination job, set the default CUPS server back to local.
-
-CHANGES IN V1.0.73
-
- - cups-browsed: Added missing
- utils/org.cups.cupsd.Notifier.xml file.
-
-CHANGES IN V1.0.72
-
- - cups-browsed, implicitclass: Added load balancing
- functionality. If there are several remote CUPS printers
- with the same name, they for locally a cluster represented
- by a print queue with this name. This printer prints through
- a special backend (implicitclass) which makes cups-browsed
- find the best destination remote queue (fewest jobs,
- enabled) for this job.
- - cups-browsed: Added protection against accidental deletion of
- print queues generated by cups-browsed. These queues now get
- automatically re-created.
- - cups-browsed: Added LDAP support. Appropriately configured via
- cups-browsed.conf remote printers made available via LDAP will be
- looked up and local queues pointing to them created. Thanks to
- Raphael Geissert (atomo64 at gmail dot com) for contributing this
- patch (Debian bug #795185).
- - cups-browsed: Introduced new handling for the default
- printer using cache files. So we do not need to keep an auto-generated
- queue because it is set as default printer. If the auto-generated
- queue disappears, the old local printer is set as default again and
- when it re-appears it returns to be the default printer.
- - cups-browsed: Added infrastructure for subscribing to CUPS
- notifications for things like improved default printer handling,
- load balancing, ...
- - foomatic-rip: Prevent crash when supplying "media" option with empty
- value ("media=", Ubuntu bug #1479871).
- - pdftoopvp: Adaptations to API changes on Poppler 0.34.0, note that
- this patch disables color management in this filter. Thanks to
- Vincent le Garrec and Andreas K. Huettel for the patch (Bug #1301,
- Gentoo bug #554782).
- - libcupsfilters, bannertopdf, foomatic-rip, gstoraster, pdftoijs,
- sys5ippprinter, pdftoopvp, pdftops, pdftoraster, rastertoescpx,
- urftopdf, texttopdf: Miscellaneous fixes for build compatibility with
- different platforms, like config.h as very first include and so on.
- Thanks to Richard Palo for the patch (Bug #1264).
- - texttopdf: Request the generic 'monospace' font alias from fontconfig
- instead of the hard-coded FreeMono. Thanks to Fabian Greffrath
- (fabian at debian dot org) for the patch (Debian bug #788048).
-
-CHANGES IN V1.0.71
-
- - texttopdf: The Page allocation is moved into textcommon.c, where it
- does all the necessary checking: lower-bounds for CVE-2015-3258 and
- upper-bounds for CVE-2015-3279 due to integer overflows for the
- calloc() call initialising Page[0] and the memset() call in
- texttopdf.c's WritePage() function zeroing the entire array. Thanks
- to Tim Waugh from Red Hat for the patch.
- - texttopdf: Upper-bounds checking (CVE-2015-3279).
-
-CHANGES IN V1.0.70
-
- - texttopdf: Fixed buffer overflow on size allocation of texttopdf
- when working with extremely small line sizes, which causes the size
- calculation to result in 0 (CVE-2015-3258, thanks to Stefan
- Cornelius fro Red Hat for the patch).
- - cups-browsed: leak fixes
- - cups-browsed: Further BrowseAllow fixing
- - cups-browsed: BrowsePoll is an array of pointers, not structures,
- so allocate room for the pointers
- - cups-browsed: Prevent NULL dereference when handling BrowseAllow
- without value
- - cups-browsed: Use memory deallocation function corresponding to
- allocation function used
- - cups-browsed: Fixes for glib source handling (Red Hat bug #1228555)
- - foomatic-rip: Allow using another shell than /bin/bash using the
- "--with-shell=..." option for "./configure". Thanks to Leonardo
- Taccari for the patch (Bug #1288).
-
-CHANGES IN V1.0.69
-
- - cups-browsed: When generating a PPD for an auto-discovered IPP
- network printer, create a "ColorModel" option only if valid
- choices are reported for it by the IPP printer.
- - cups-browsed: Updated PPD file generator for auto-generated queues
- for IPP network printers from the CUPS 2.1.x upstream code, so that
- floating-point numbers are written in a locale-neutral way
- (CUPS STR #4579).
- - cups-browsed: When checking whether a queue name already exists
- as a locally defined queue, do case-insensitive comparing as for
- CUPS printer names are case-insensitive. This assures that
- already existing queues do never get overwritten.
- - cups-browsed: Added "IPPPrinterQueueType Auto/PPD/NoPPD" directive
- to cups-browsed.conf to allow controlling how cups-browsed
- creates queues fr native IPP network printers: with PPD, with
- System V interface script, or selecting automatically.
- - pdftopdf: Center Landscape-oriented jobs correctly on the page
- if the "fitplot" or "number-up" options are used (Bug #1284).
- - pstopdf: Removed "-dUseCIEColor" from the Ghostscript command line.
- In modern Ghostscript versions (9.11 and newer) it is recommended to
- not use it with the pdfwrite and ps2write output devices any more.
- - imagetopdf: Corrections in PDF output: Let evince display the PDF
- with the correct size including margins and let ghostscript not
- complain about an invalid xref entry.
- - cups-browsed: Do not add options to the System V interface script
- which calls sys5ippprinter but set the options as defaults for the
- CUPS queue in printers.conf.
- - cups-browsed: When auto-generating a PPD-less print queue for an
- IPP network printer, determine default page size, unprintable margins,
- and color space from the printer via an IPP request.
- - imagetopdf: Debug logging should be only controlled by the LogLevel
- of CUPS, not by an awkward build time switch.
- - cups-browsed: Determine from the TXT records of the Bonjour broadcast
- of an IPP network printer whether it has color and duplex
- capabilities and if yes, let auto-generated PPD-less print queues
- use appropriate command line options to make use of these
- capabilities.
- - imagetopdf: Make this filter also work with auto-generated PPD-less
- print queues for IPP network printers.
- - sys5ippprinter: Renamed from pdftoippprinter to reflect that
- it is a System 5 interface script and does not accept only
- PDF as input.
- - pdftoippprinter: Support also PWG Raster and JPEG as input formats
- so that an auto-generated, PPD-less queue for an IPP printer emulates
- an IPP Everywhere printer.
-
-CHANGES IN V1.0.68
-
- - cups-browsed: Numeric IDs for GSources of the glib event
- loop must be positive integers greater than zero according
- to the documentation of the g_source_get_id() function.
- Taken care of this at all places.
- - cups-browsed: Added conditionals so that it also builds with
- CUPS 1.5.x (but then withou support for automatically creating
- queues for IPP network printers). Thanks to Johannes Meixner from
- SUSE for the patch (Bug #1268).
- - Ricoh-PDF_Printer-PDF.ppd: Added PPD file for Ricoh's PDF printers
- (experimental). Thanks to Ulrich Wehner from Ricoh for the file.
-
-CHANGES IN V1.0.67
-
- - cups-browsed: Use g_source_remove() instead of g_source_destroy()
- for killing auto shutdown timers (Ubuntu bug #1427344).
-
-CHANGES IN V1.0.66
-
- - cups-browsed: SECURITY FIX: Fixed a bug in the remove_bad_chars()
- failing to reliably filter out illegal characters if there are two
- or more subsequent illegal characters, allowing execution of
- arbitrary commands with the rights of the "lp" user, using forged
- print service announcements on DNS-SD servers (Bug #1265).
- - pdftoopvp: Added conditionals to also build with Poppler 0.31.0
- and newer. Thanks to Armin K. (krejzi at email dot com) for the
- patch (Bug #1254).
-
-CHANGES IN V1.0.65
-
- - cups-browsed: Listen for NetworkManager changes (Red Hat bug #975933).
- - cups-browsed: Fix for memory leak introduced in BZR rev 7059.
- - cups-browsed: Memory leak/uninit fixes.
- - cups-browsed: Cache prepared browse data to send.
- - cups-browsed: Only get local notifications once per BrowsePoll run.
- - cups-browsed: Fix BrowsePoll now notifications work properly. Need
- to maintain a list of printers to keep alive for the case of there
- being no notifications of changes.
- - cups-browsed: Use local browsepolling for getting initial printer
- list.
- - cups-browsed: Ignore browse packets for deleted printers.
- - cups-browsed: Cache connection to local cupsd.
- - cups-browsed: Use notifications to track local printers.
- This avoids expensive calls to cupsGetDests().
- - cups-browsed: Manage subscriptions for local browsepolling.
- - cups-browsed: Track notify-sequence-number for notifications.
-
-CHANGES IN V1.0.64
-
- - cups-browsed: Added PPD file generator for IPP Everywhere
- printers. If auto-setup of discovered IPP printers is
- activated ("CreateIPPPrinterQueues Yes" in
- cups-browsed.conf), the printer provides suitable capability
- information via a Get-Printer-Attributes IPP call, and
- prints PWG or PostScript input, a PPD is auto-generated
- based on the Get-Printer-Attributes IPP response. Otherwise
- a System-V interface script is used as befreo. Advantage of
- the PPD file is that current print dialogs aloow access to
- the options, no IPP request done by the dialog is
- required. The PPD generator code is borrowed from the CUPS
- 2.1.x development code repository. It will perhaps be
- removed in the future when CUPS provides proper API function
- for its PPD generator.
-
-CHANGES IN V1.0.63

- - foomatic-rip: Added hint to man page that direct, spooler-less mode
- is mainly for testing and debugging (Bug #1253).
- - foomatic-rip: Added a symlink of the filter to the binary executable
- directory (usually /usr/bin), so that LSB compliance test scripts
- work (Bug #1255).
- - cups-browsed: Fixed CUPS Browsing timeouts. Thanks to Tim
- Waugh from Red Hat for the patch (Bug #1252, Red Hat bug
- #1189254).
-
-CHANGES IN V1.0.62
-
- - cups-browsed: Allow underscore characters in print queue names.
- Thanks to Tim Waugh from Red Hat for the bug report (Bug
- #1241).
- - pdftops: Apply workarounds for Kyocera also to Utax printers
- as Utax uses hard- and software from Kyocera. Thanks to Edward
- Huang from Kyocera.
- - cups-browsed: Added support for "BrowseAllow All" in the
- cups-browsed.conf file.
- - cups-browsed: Reorder inclusion of headers for compatibility
- with NetBSD (Bug #1235).
- - imagetopdf, pdftopdf: Correct handling of hardware copies in
- PJL/JCL and/or when the PPD file has a "Copies" option.
-
-CHANGES IN V1.0.61
-
- - cups-browsed: Fixed memory leak when a
- cups-browsed-generated print queue is the default
- printer. Thanks to Tim Waugh from Red Hat for the patch (Red
- Hat bug: #1119290).
- - cupsfilters.drv, *-PDF.ppd, textonly.ppd: Added
- "*cupsFilter2: ..." lines to the PPD files to support
- data-format-specific behavior of backends, especially of the
- IPP backend.
-
-CHANGES IN V1.0.60
-
- - cups-browsed, pdftoippprinter: Do not confuse the PDL "PCLm"
- with "PCL". The former is a proprietary, PDF-based raster
- format and has nothing to do with PCL.
- - cupsfilters.drv: Corrected the CMD: field of the device ID,
- it must read "PWGRaster" there to conform to the PWG standard.
-
-CHANGES IN V1.0.59
-
- - cupsfilters.drv: Added PPD file for a Generic IPP Everywhere
- Printer, generating PWG Raster output.
- - gstoraster, pdftoraster, imagetoraster: Allow PWG Raster
- output with print queues using a PPD file, using the new
- "PWGRaster" PPD attribute.
- - pdftoraster: Removed "cm_disabled" flag in selectConvFunc()
- - libcupsfilters: Allowed color management to continue while
- invalid input
- - rastertopdf: Streamlined PDF conversion code
- - rastertopdf: Invert all CUPS_CSPACE_K documents by default
- - foomatic-rip: Clean trailing white space from PPD file lines to
- avoid a segfault caused by it (Bug #1227).
-
-CHANGES IN V1.0.58
-
- - pdftoraster: Changed ICC profile get function to accept a
- PPD fallback profile.
- - pdftoraster: Fixed handling of cupsColorSpaces 18,19,20.
- - rastertopdf: Added test feature to force color management if
- "profile=" option is specified.
- - rastertopdf: Grayscale color conversion now properly inverts
- bits.
- - rastertopdf: Code cleanup for prepare_pdf_page().
- - rastertopdf: Implemented basic 8bit->8bit color space
- conversions.
- - rastertopdf: Added black point compensation.
- - rastertopdf: Added handling of color rendering intent.
- - gstoraster, imagetoraster, pdftoraster, rastertopclx,
- rastertopdf, foomatic-rip: Use color management functions in
- libcupsfilters.
- - libcupsfilters: Modified code formatting and documentation in
- the color management functions.
- - libcupsfilters: Fixed string handling and added debug log
- messages in the color management functions.
- - libcupsfilters: Fixed Adobe RGB matrix for proper rendering
- (transpose)
- - libcupsfilters: Moved color management functions from the
- individual filters to the libcupsfilters library.
-
-CHANGES IN V1.0.57
-
- - rastertopclx: Fixed implicit declaration of
- colord_get_inhibit_for_device_id.
- - Build system: Explicitly link to libm as -lm was dropped
- from cups-config --libs.
- - libcupsfilters, foomaticrip, gstoraster, imagetoraster,
- pdftoraster, rastertopclx, rastertopdf: Handle absence of
- colord or D-Bus gracefully (Ubuntu bug #1356405).
-
-CHANGES IN V1.0.56
-
- - rastertopdf: Some code polishing and removal of now unneeded
- functions
- - rastertopdf: Reduced color space handling to only
- PWG-supported color spaces
- - rastertopdf: Added colorspace calibration function; included
- optional "/Alternate" PDF key for ICC profile embedding
- - rastertopdf: Colorspace sRGB now embeds srgb icc profile;
- implemented ICC Profile embedding (PDF 1.3 spec)
- - rastertopdf: Added basic color calibration
- - rastertopdf: Implemented ICC Profile creation code for IPP
- Everywhere (from PWG raster)
- - pdftoraster: Added colord handling of ICC profiles
- - kmdevices.cpp/.h: Added interface for Kolor Manager
- - cups-browsed: Do not consider a remote CUPS queue as raw if
- the TXT record is NULL as for queues broadcasted by the
- legacy CUPS method the TXT record does not exist. Now
- consider a queue with NULL TXT record only as raw if the
- domain entry is not empty (which tells that the queue is
- Bonjour-broadcasted (Bug #1223).
- - cups-browsed: Do also not mark a discovered printer as
- already provided by another server when the other server's
- queue has "unconfirmed" status. Mark the other queue with
- "disappeared" or "unconfirmed" status as duplicate of the
- discovered printer so that the new queue for the discovered
- printer does not get removed when the entry for the other
- queue times out.
-
-CHANGES IN V1.0.55
-
- - pdftopdf: Fixed manual duplex by adding a blank page to evn
- pages if the total number of pages of the document is
- odd. Otherwise the last page of the document would stay in
- the input tray. This fixes also a side effect as the set of
- even pages reducing to a zero page job if the job consists
- of only one page, making Poppler's pdftops error out (Ubuntu
- bug #1340435).
- - cups-browsed: Do not mark a discovered printer as already
- provided by another server when the other server's queue has
- "disappeared" status. This queue can be from the same server
- before it changed its name.
- - cups-browsed: Do not create a local queue pointing to a
- remote raw queue (Ubuntu bug #1335211).
- - foomatic-rip, imagetoraster, pdftoraster, rastertopclx,
- rastertopdf: Added colord "device_inhibit" support for
- color-managed filters.
- - foomatic-rip: Let it also build correctly on systems which
- already provide the strlcat() and strlcpy() functions, like
- Mac OS X. Thanks to Matt Broughton for reporting this
- (bug #1215).
- - bannertopdf: Added support for PPD-less printing, especially
- one gets a useful test page with PPD-less queues now.
- - bannertopdf: Fixed "Printer Location" and "Driver Version"
- entries on the test page/the banners.
- - bannertopdf: Added new PDF template files which contain the
- text strings appropriate to the banners, before the banners
- were all equal, without text. Thanks to Johannes Meixner
- from SUSE/Novell for this fix (Bug #1209).
- - bannertopdf: Fixed Makefile to mark it dependent on
- libfontembed.la. Thanks to Tim Waugh from Red Hat for the
- patch (Red Hat bug #1106101).
- - pstopdf: Use "grep -E" instead of "grep -P" as the latter
- generates executable code and executes it, requiring
- "execmem" privileges which could be not available in some
- security policies. Thanks to Tim Waugh from Red Hat for the
- patch (Red Hat bug #1079534).
- - foomatic-rip: NetBSD does not provide a mkstemps() function,
- use appropriate workaround then (Bug #1211).
- - cups-browsed: Reorder inclusion of headers for compatibility
- with NetBSD (Bug #1212).
- - pdftoraster: Fixed segfault caused by introduction of
- "no-color-management" option (Bug #1214).
- - libcupsfilters: Let cupsRasterParseIPPOptions() also accept
- "pwg-raster-document-type" settings with hyphen between
- color space name and color depth.
-
-CHANGES IN V1.0.54
-
- - pdftoraster: Support for output in the color spaces 18
- (CUPS_CSPACE_SW, sGray), 19 (CUPS_CSPACE_SRGB, sRGB), and 20
- (CUPS_CSPACE_ADOBERGB, Adobe RGB). No color management
- appropriate to these color spaces is added yet.
- - foomatic-rip, gstoraster, imagetoraster, pdftoraster,
- rastertopclx: added boolean option "no-color-management" to
- suppress all forms of color correction when
- color-calibrating the printer.
- - pdftops: Default to "hybrid" setting for the PDF->PostScript
- renderer.
- - pdftoraster: Produce correct (compressed) PWG Raster output
- when requested by using the correct mode in
- cupsRasterOpen().
- - rastertopdf: Added new filter to convert PWG Raster input
- into a PDF file (using QPDF). This filter makes CUPS
- supporting the PWG Raster input format which is required to
- be supported by IPP Everywhere printers, making a shared
- CUPS queue emulating an IPP Everywhere printer. This is a
- first implementation which supports the black, RGB, CMYK,
- sGray, sRGB, and Adobe RGB color spaces (all mapped to
- DeviceGray, DeviceRGB, and DeviceCMYK resp. in the PDF
- output) with 1, 8, and 16 bits per component color
- depth. sGray, sRGB, and Adobe RGB are currently also mapped
- to DeviceGray and DeviceRGB and do not have the correct
- color management yet, so color output is not absolutely
- correct. Note that mime.types of CUPS up to 1.7.2 has a bug
- which prevents PWG Raster to be recognized, the
- "priority(100)" of the rule needs to be changed to
- "priority(150)".
- - foomatic-rip: Corrected declaration of print_pdf() function in
- pdf.h file (Debian bug #748028).
- - foomatic-rip: Let it also build with uclibc which does not
- provide the mkstemps() function. Thanks to Andreas K.
- Huettel for the patch (Gentoo bug #509884).
- - cups-browsed: Create local queues also to access classes on
- remote CUPS servers (Ubuntu bug #1313741).
- - cups-browsed: Let a newly discovered printer not only
- overtaking an existing printer entry if it is from the same
- host (usually IPP -> IPPS) or without host entry
- (unconfirmed local queue from previous cups-browsed session)
- but also if it is marked disappeared. So printer entries get
- correctly migrated when things like a host name change of
- the remote server happen.
- - cups-browsed: Always do case-insensitive comparing of
- strings, as CUPS queue names and URIs are case-insensitive
- (CUPS STR #4411).
-
-CHANGES IN V1.0.53
-
- - foomatic-rip: Fixed segfault when creating log file (Bug
- #1206).
- - cups-browsed: SECURITY FIX: Fix on usage of the
- "BrowseAllow" directive in cups-browsed.conf. Before, if the
- argument of a "BrowseAllow" directive is not understood it
- is treated as the directive not having been there, allowing
- any host if this was the only "BrowseAllow" directive. Now
- we treat this as a directive which no host can fulfill, not
- allowing any host if it was the only one. No "BrowseAllow"
- directive means access for all, as before (Bug #1204).
- - cups-browsed: SECURITY FIX: Further improvement on the fix
- in 1.0.51 as it was insufficient. In addition, some fixes
- against OOB access are done. Thanks to Sebastian Krahmer for
- the patch (SUSE/Novell bug #871327).
-
-CHANGES IN V1.0.52
-
- - texttopdf: Make sure that margin changes for prettyprint
- get applied.
- - texttopdf, imagetopdf, imagetoraster: Range-check paper
- dimensions and margins taken from the PPD file and correct
- them if needed (Bug #1195).
-
-CHANGES IN V1.0.51
-
- - cups-browsed: SECURITY FIX to prevent arbitrary code
- injection into the System V interface scripts generated for
- queues for discovered native IPP printers by a malicious IPP
- print service with forged make/model and/or PDL string.
-
-CHANGES IN V1.0.50
-
- - pdftops: Let old HP LaserJet printers (model number without
- letter, like "LaserJet 3" or "LaserJet 4000") use Poppler
- instead of Ghostscript (Debian bug #742765).
- - pdftops: Improved workaround for Toshiba printers. Instead
- of using Poppler do not emit TrueType fonts with Ghostscript
- (Ubuntu bug #998087).
- - cups-browsed: Build the device URIs for all local queues we create
- with the CUPS library function httpAssembleURIf() for proper
- percent escaping of characters which are not allowed in URIs
- (Bug #1187).
-
-CHANGES IN V1.0.49
-
- - pdftops: Use Poppler also for Toshiba printers (Ubuntu bug
- #998087).
- - pdftops: Fixed typo which always made PostScript level 2 being
- generated when using Poppler's pdftops (Ubuntu bug #1294370).
-
-CHANGES IN V1.0.48
-
- - cups-browsed: Fix for a crash which happens on Bonjour reports of
- printers without "product", "usb_MDL", and "ty" fields in the
- text record (Ubuntu bug #1284834).
- - cups-browsed: In README and in the sample startup scripts/configs
- for System V Init and Upstart taken into account the fact that it
- is not required any more to start avahi-daemon before starting
- cups-browsed.
-
-CHANGES IN V1.0.47
-
- - pdftoopvp: SECURITY FIX for CVE-2013-6474, CVE-2013-6475,
- and CVE-2013-6476: Introductionof gmallocn and gmallocn3
- to protect against arbitrary code execution with the
- privileges of the "lp" user via malicious PDF files. Also
- restrict the directory from where OPVP drivers can get
- loaded.
- - urftopdf: SECURITY FIX for CVE-2013-6473: Two heap-based
- buffer overflow flaws in urftopdf. If a malicious URF file
- were processed it could lead to arbitrary code execution
- with the privileges of the "lp" user.
- - pdftopdf: Fixed typo in initialization which sets the default
- value page border to an undefined value. Thanks to Helge
- Blischke for the patch.
- - cups-browsed: Check for changes of the URI of a queue which
- we have created and correct the URI if needed, especially if
- a queue was not removed on shutdown of cups-browsed (default
- printer or still having jobs) and before restart of
- cups-browsed the server's DNS-SD-provided has changed.
- - bannertopdf: Support PDF forms as banner template. This allows
- especially internationalized banner pages. Forms can contain
- fields for any CUPS/IPP value and get automatically filled
- Thanks to Andrew V. Stepanov from ALT Linux (Bug #1170,
- also first step to fix Ubuntu bug #1196986).
-
-CHANGES IN V1.0.46
-
- - gstoraster: Ignore SIGCHLD, rely on waitpid instead. Thanks
- to Lauri Tirkkonen (Bug #1184).
- - gstoraster: Fix two instances of insufficient EINTR handling.
- Thanks to Lauri Tirkkonen (Bug #1184).
-
-CHANGES IN V1.0.45
-
- - cups-browsed: Under Upstart load the AppArmor profile
- (Ubuntu bug #1276630).
- - cups-browsed: Added auto-shutdown feature for on-demand use
- of cups-browsed (for example on mobile devices). With auto
- shutdown active, cups-browsed terminates after a certain
- time interval (30 sec by default) without having any remote
- printer to make available locally. The mode can be turned
- on, turned off (default) or set to automatically be off
- while avahi-daemon is running an on otherwise (controlled by
- avahi-daemon running on-demand). The mode and the timeout
- interval can be selected by command line options, the
- configuration file, and sending signals to cups-browsed
- (on/off only).
- - cups-browsed: To make Bonjour-discovered printers locally
- available avahi-daemon does not need to be started before
- cups-browsed and does not need to stay continuously running
- while cups-browsed is running. Bonjour-discovered printers
- are now added whenever avahi-daemon starts and removed
- whenever avahi-daemon stops and cups-browsed keeps
- running. This makes it easier to use cups-browsed in
- different system-configurations and also on systems with
- daemons running on-demand (like mobile systems).
- - foomatic-rip: Fixed pid_t/int function prototype mismatch
- (Bug #1182).
- - Fixed --with-pdftops-path and --with-pdftocairo-path options
- in ./configure (Bug #1181).
- - foomatic-rip: Do not use PATH_MAX for the length of static
- strings which are supposed to hold a command line. Use our
- own CMDLINE_MAX constant to set them to a length of 65535
- bytes (Ubuntu bug #1019662, Debian bug #738440).
- - pdftops: Log command lines of renderer (Ghostscript, pdftops,
- pdftocairo, acroread) and of pstops in CUPS' error_log (in
- debug mode).
-
-CHANGES IN V1.0.44
-
- - README: Documented the "hybrid" choice for the PDF renderer
- in the pdftops filter.
- - pdftoippprinter: Handle missing Ghostscript/Poppler for all
- output formats.
- - cups-browsed: Minor corrections in the error messages.
- - gstopxl: Support for PPD-less printing. Resolution,
- InputSlot, Duplex, and ColorModel are set also without PPD
- file now.
- - Added another sample PPD file for a native PDF printer,
- Fuji_Xerox-DocuPrint_CM305_df-PDF.ppd. Thanks to Adrian
- Johnson for contributing this PPD file.
-
-CHANGES IN V1.0.43
-
- - cups-browsed: When automatically setting up a PPD-less print
- queue for an IPP network printer add make/model info as an
- additional "make-and-model" command line option to the call
- of the pdftoippprinter filter, this way filters can do
- make/model-specific exceptions (quirk rules).
- - pdftopdf: Take page size from the command line if not
- already given by the PPD file, this way
- "fitplot"/"fit-to-page" also works with PPD-less printing.
- - libcupsfilters: cupsRasterParseIPPOptions() did not set
- sRGB color space.
- - libcupsfilters: cupsRasterParseIPPOptions() did not set
- Tumble with "Duplex=DuplexTumble".
- - pdftopdf: Fixed software copy generation logic for printers
- with hardware copy generation, but without collate support
- (Ubuntu bug #1259240).
- - pdftops: Let Ghostscript output PostScript level 3 also for
- PPD-less printing, but not for HP lasers or when make/model
- info is not supplied.
- - cups-browsed: removed duplicate definition of ippSetVersion.
- - foomatic-rip: Take PATH_MAX constant from limits.h if
- available instead defining it's own version conflicting with
- kfreebsd. Thanks to Peter Green for the patch (Debian bug
- #731658).
- - pdftops: Ignore "landscape", "orientation-requested",
- "fit-to-page", and any page geometry options. The first two
- do not make sense on PDF input and therefore should only be
- used in ...topdf filters used before pdftopdf, the others
- are already taken care of by pdftopdf so that pdftops gets
- pages with print-ready page geometry.
- - pdftops: Added "-nocenter" to the call of "pdftops
- -origpagesizes" (Poppler/freedesktop.org bug #72312,
- comments #6 and #7).
- - pdftopdf: If there is no PPD file or no
- "*LandscapeOrientation:" keyword in the PPD file, rotate
- counterclockwise, not clockwise to fit a landscape-oriented
- page on a portrait-oriented sheet (See
- Poppler/freedesktop.org bug #72312, comment #6).
- - pstopdf: Support for the "landscape" and
- "orientation-requested" options (Ubuntu bug #1243484).
- - pdftops: Support for PPD-less printing on PostScript
- printers: duplex, resolution, input tray, color mode, and
- make/model (for quirk rules) can now be supplied by the
- command line, pdftopdf takes care of the page geometry.
- - libcupsfilters: cupsRasterParseIPPOptions() allows
- specifying resolutions without unit now, assuming dpi then
- (example: "600x600").
- - Fixed "--with-cups-rundir" and "--with-cups-domainsocket"
- options in configure (Bug #1174).
- - pdftops: After fixing the output of rotated PDF pages
- (usually landscape-oriented pages rotated by pdftopdf) in
- Poppler (Poppler/freedesktop.org bug #72312) corrected the
- use of "pdftops -origpagesizes" in pdftops appropriately
- (Red Hat bug #768811).
-
-CHANGES IN V1.0.42
-
- - pdftoippprinter: Check also the presence of Ghostscript and
- use pdftoraster if Ghostscript is missing.
- - gstoraster: At build time use the path for Ghostscript which
- our build system already finds for pdftops.
- - pdftoraster: Take into account rotate field in PDF header,
- when pdftopdf rotates a page to fit the paper it sets the
- rotate field and does not swap the width and height entries.
- - pdftoippprinter: Made PCL 5c/e printing working correctly,
- by first adding support for unprintable margins and
- defaulting to 12pt margins if no margin info is supplied,
- and second, by doing color printing always in RGB color
- space.
- - rastertopclx: Improved support for PPD-less printing,
- allowing color printing with (s)RGB color space. Output is
- in sRGB then.
- - rastertopclx: Determine page size and select correct PCL
- command for the page size more reliably, especially for
- landscape-oriented pages.
- - gstoraster, pdftoraster: Do correct PWG Raster output, allow
- switching to PWG Raster via "media-class=PwgRaster" option
- and CUPS Raster via "media-class=". Default for PPD-less
- printing is PWG Raster.
- - gstoraster, pdftoraster: Support applying unprintable
- margins for PPD-less mode with CUPS Raster output.
- - libcupsfilters: Added support for "media-left-margin",
- "media-right-margin", "media-bottom-margin", and
- "media-top-margin" IPP options to specify unprintable
- margins in 1/100th of a mm, to allow PPD-less printing with
- unprintable margins (esp. PCL 5c/e with rastertopclx).
- - libcupsfilters: Do not set "MediaClass" to "PwgRaster" when
- we request a CUPS Raster header and not a PWG Raster header.
- - libcupsfilters: Fixed typo in a debug message in the colord
- support part.
- - cupsfilters.convs: Corrected cost factor of
- vnd.cups-postscript -> vnd.cups-raster conversion with
- gstoraster, so that input data of the type
- application/vnd.adobe-reader-postscript is converted
- correctly (not via pstotiff). Thanks to Tim Waugh from Red
- Hat for this patch
- - cups-browsed: Fixed several memory leaks by adding missing
- free() calls and removing an unneeded strdup(). Thanks to
- Jaromir Koncicky from Red Hat for the patch (Red Hat bug
- #1027317).
- - Backends parallel and serial: Fixed logical expressions for
- error handling (Bug #1172).
- - libcupsfilters: Moved filter/colord.[ch] into the library as
- this code is now used by both gstoraster and foomatic-rip.
- - libcupsfilters: Made the names of the flags to tell that the
- header is already included unique in all API header files.
- - foomatic-rip: Moved foomatic-rip's upstream home from the
- foomatic-filters package to cups-filters, to make it easier
- for distributions to ship and maintain a complete printing
- stack and also to make upstream maintenance and development
- easier.
- - foomatic-rip: Removed support for all the non-CUPS printing
- environments as they are discontinued upstream. Now
- foomatic-rip only works as a CUPS filter and in a spooler-less
- direct mode, where the latter is mainly for testing and
- debugging. Thanks to Anshul Kushwaha (anshulkushwaha1 at gmail
- dot com) for doing this as a Google Summer of Code 2013 project.
- - foomatic-rip: Eliminated compiler warnings.
- - foomatic-rip: fixed "endswith()" string utility function.
- - foomatic-rip: Removed unneeded HAVE_DBUS conditionals.
- - gstoraster: Fixed build system for gstoraster use D-Bus for
- colord support.
- - libcupsfilters: Recognize more Adobe-generated CMYK JPEGs to
- take into account their inverted colors (Bug #1169).
- - pdftopdf: When checking whether double-sided printing is
- chosen, do not only check for the choice names "DuplexNoTumble"
- and "DuplexTumble" but also for "LongEdge", "ShortEdge",
- "Top", and "Bottom", as CUPS does (Bug #1167).
-
-CHANGES IN V1.0.41
-
- - cups-browsed: Added support for automatic PPD-less setup of
- print queues for IPP printers discovered on the network via
- Bonjour. Supported are printers with known languages (PWG
- Raster, PDF, PostScript, PCL XL, PCL 5c/e), especially also
- IPP Everywhere printers. This functionality is especially
- ment for mobile devices to be able to print without printer
- setup tool and without printer driver/PPD collection.
- - cups-browsed: Fixed a Valgrind-reported issue.
- - pdftoippprinter: New filter for PPD-less printing. The filter
- will be configured as System-V interface script for a print
- queue for a discovered IPP network printer generated by
- cups-browsed.
- - rastertopclx: Added support for PPD-less printing. Without
- PPD the filter generates PCL 5e.
- - cups-browsed: Fixed socket leaks in recent IPP subscriptions
- changes. Thanks to Tim Waugh from Red Hat for the patch (Red
- Hat bug #1021512).
-
-CHANGES IN V1.0.40
-
- - pdftops: Introduced new "hybrid" renderer: Here usually
- Ghostscript is used, but if the printer is a Brother,
- Minolta, or Konica Minolta Poppler's pdftops gets used. This
- is a quirk rule to work around bugs in the PS interpreters
- of the printers.
- - Fixed format string issues and added __attribute__ wording
- to printf-like functions to catch any regressions. Thanks to
- Tim Waugh from Red Hat for the patch.
-
-CHANGES IN V1.0.39
-
- - pdftops: Fix for landscape PDF handling. Do not use the
- command line options "-origpagesizes" and
- "-choosePaperByPDFPageSize" of Poppler's pdftops utility on
- already processed PDF data. Thanks to Tim Waugh from Red Hat
- for the patch.
- - cups-browsed: Improve the efficiency of BrowsePoll by using
- IPP notifications when possible. It falls back to the
- previous behaviour if it is not possible to use this
- optimization. Thanks to Tim Waugh from Red Hat for the patch.
-
-CHANGES IN V1.0.38
-
- - pdftops: Added "-dNOINTERPOLATE" to the Ghostscript command line
- for quicker processing of embedded bitmaps.
- - pstopdf: Added "-dUseCIEColor" to the Ghostscript command line
- to assure compatibility with newer Ghostscript versions (9.08
- and newer).
-
-CHANGES IN V1.0.37
-
- - Added example configuration files for systemd and Upstart. Thanks
- to Tomáš Chvátal for the systemd file.
- - Build system: Make sure that gstoraster gets linked against the
- libcupsfilters of the currently built package and not of the
- system. Thanks to Tomáš Chvátal.
- - cupsfilters.convs: Reworked the cost factors of the filters to
- avoid bogus filter chains like pstotiff|imagetopdf instead of
- pstopdf|pdftopdf for PostScript->PDF. Thanks to Tim Waugh from
- Red Hat for the report.
- - pdftopdf: Accept additional command line options for PPD-less
- printing.
- - cups-browsed: Fixed building with CUPS 1.5.x and older,
- ippSetVersion() was missing under the accessor function definitions
- for backward compatibility.
-
-CHANGES IN V1.0.36
-
- - Fixed libdl detection in configure. Thanks to Andreas Huettel and
- Yuta Satoh (Gentoo bug #478642).
- - cups-browsed: Allow BrowsePoll operation also access print queues
- on older CUPS servers. Thanks to David Mohr for the patch.
- - cups-browsed: Assure that it always applies to the local CUPS
- daemon and never to a remote one specified via client.conf
- (Ubuntu bug #1207203).
- - pdftoopvp, pdftoijs, pdftoraster, bannertopdf: Made code working
- with Poppler 0.24.x (Bug #1144).
- - gstoraster: Silenced compiler warnings.
- - gstoraster, pdftoraster: Added support for PPD-less printing
- controlled by IPP attributes (CUPS 1.7.x+ only).
- - gstoraster, gstopxl: Moved these filters from Ghostscript to
- cups-filters as upstream home.
- - libcupsfilters: Added new cupsRasterParseIPPOptions() API
- function for PPD-less printing controlled by IPP attributes
- (raster.h, CUPS 1.7.x+ only).
- - pdftopdf: Added support for page labels. "page-label" option and
- "CLASSIFICATION" environment variable. Thanks to Tim Waugh from
- Red Hat for the patch.
- - pdftops: If one or more of the PDF-to-PS renderers (Ghostscript,
- Poppler pdftops, Poppler pdftocairo, acroread) is not installed
- at build time, pre-fill the appropriate executable's path with the
- executable name to allow the use of this renderer when it gets
- installed later (Debian bug #716842).
- - cups-browsed: Do not resolve host names of remote printers discovered
- via CUPS broadcasts (Bug #1141).
- - Added man pages for cups-browsed and cups-browsed.conf. Thanks to
- Brian Potkin for the contribution (Debian bug #714460).
- - Install also escp.h, it is useful for .drv files.
-
-CHANGES IN V1.0.35
-
- - pdftoraster: Silenced compiler warning (Bug #1092).
- - bannertopdf: Fixed typo which prevented the host name to be shown
- (Bug #1115).
- - README: Fixed info about the PPD keyword cupsManualCopies (Bug
- #1086).
- - Modified the cost factors of the filters to avoid unneeded PDF
- conversion detours when the input data is PostScript. Instead of
- pstopdf->pdftopdf->pdftops and pstopdf->pdftopdf->gstoraster we
- get pstops and pstops->gstoraster now (Bug #1138).
- - pdftops: Added experimental support for pdftocairo as PDF renderer.
- Note that PostScript level 1 output and PDF input with color
- spaces other than DeviceRGB, DeviceGray, sRGB or sGray is not
- supported. PDFs generated by Cairo (for example when printing from
- evince) uses only supported color spaces. Thanks to James Cloos
- for the patch (Bug #1139).
- - cups-browsed: Changed default of browsing protocols fron none to
- both DNS-SD and CUPS.
- - pdftops: Let Poppler generally generate PostScript level 3 if the
- PPD identifies the printer as PS3 printer, make an exception of
- sending PostScript Level 2 only for HP's laser printers, to not
- compromise print quality and performance on all PS3 printers only
- due to some buggy HP models (Debian bug #712949, see also Ubuntu bug
- #277404).
- - Install pcl.h, it is needed by cupsfilters.drv. Thanks to Jiri
- Popelka from Red Hat for the patch (Bug #1133).
- - Make cups-filters building with automake 1.13. Thanks to Andreas K.
- Huettel (dilfridge) on IRC.
- - libcupsfilters, libfontembed, pdftopdf, texttopdf, cups-browsed:
- Fixed several resource leaks and other problems. Thanks to Jiri
- Popelka from Red Hat for the patches (Bug #1116).
-
-CHANGES IN V1.0.34
-
- - cups-browsed: Fixed build with OpenBSD (Bug #1103).
- - pdftopdf: Enabled hardware copy generation, if available.
- - pdftopdf: Fixed evenDuplex logic.
- - cups-browsed: If a queue left over from the last session
- gets confirmed, fill in the data structure with the Bonjour
- parameters, also update the Bonjour parameters if a local
- queue is upgraded from IPP to IPPS.
-
-CHANGES IN V1.0.33
-
- - cups-browsed: Added NULL check (Bug #1106).
-
-CHANGES IN V1.0.32
-
- - cups-browsed: Shared algorithm to generate local queues based on
- browsed remote queue data between Bonjour and CUPS browsing, as the
- simpler method used for CUPS browsing could overwrite local print
- queues and had de-duplication problems, for example if the server
- appears on two IPs in the network (connected by both ethernet and
- WLAN).
- - cups-browsed: CUPS broadcasting also broadcasted non-shared,
- especially cups-browsed-generated printers. Switched to detection
- of non-shared printers by the appropriate bit in the printer-type
- bit field IPP attribute.
- - cups-browsed: Made CUPS broadcasting work also without BrowseAllow
- lines in cups-browsed.conf. In this case we accept all remote
- printers (Ubuntu bug #1163764).
- - README: Updated documentation for cups-browsed.
- - Added more comments and examples to /etc/cups/cups-browsed.conf.
- - cups-browsed: Added support for "...:<port>" extensions of
- BrowsePoll addresses. Thanks to Tim Waugh from Red Hat (Ubuntu
- bug 1159213).
-
-CHANGES IN V1.0.31
-
- - cups-browsed: cups-browsed removed valid local queues pointing to
- remote queues when cups-browsed did not shut down cleanly after
- the previous session, leaving the user with missing local accessor
- queues for some of the remote CUPS queues (Ubuntu bug #1131149).
- - Fixed build system to allow parallel or multilib builds. Thanks to
- Timo Gurr for the patch (Bug #1104).
- - pdftopdf: Improved error output.
- - pdftopdf: getRotation now handles unusual cases more graceful
- (probably fixes Ubuntu Bug #1154318).
- - Fixed build system to allow building without Avahi. In this case
- a cups-browsed with only CUPS broadcasting/browsing will get
- built. Thanks to Tim Waugh from Red Hat (Bug #1101, Bug #1102).
-
-CHANGES IN V1.0.30
-
- - cups-browsed: Do not remove a generated local print queue when
- it was made the system default printer (Ubuntu bug #1146407).
- - texttopdf: Fixed corrupted pdf when a utf-8 title is given and
- corresponding crash with 'prettyprint' (Ubuntu Bug #1137438).
- - cups-browsed: Added CUPS Broadcasting for sharing local printers
- to remote CUPS clients with CUPS 1.5.x and older. Thanks to Tim
- Waugh from Red Hat.
- - cups-browsed: Added sample config-file and build-time default
- setting options. Thanks to Tim Waugh from Red Hat.
- - cups-browsed: Added CUPS browsing and BrowsePoll functionality, to
- be backwards compatible to CUPS 1.5.x and older servers. Thanks
- to Tim Waugh from Red Hat.
- - pdftopdf: Fixed incorrect evenDuplex page insertion (Bug #1088).
- - pdftoopvp: Let it build with Poppler 0.22.x. Thanks to Koji Otani
- from BBR Inc. (Bug #1089).
-
-CHANGES IN V1.0.29
-
- - Fixed ./configure option "--with-rcdir=no". Thanks to Jiri
- Popelka from Red Hat (Bug #1091).
-
-CHANGES IN V1.0.28
-
- - cups-browsed: Do not create CUPS queues for shared local CUPS
- printers.
-
-CHANGES IN V1.0.27
-
- - cups-browsed: The daemon crashed if there is no local CUPS queue
- at all. Fixed.
-
-CHANGES IN V1.0.26
-
- - Some fixes in README and INSTALL.
- - cups-browsed: Added daemon to browse the Bonjour broadcasts of
- shared remote CUPS printers and automatically add local raw queues
- pointing to them, to resemble the behavior of the former CUPS
- broadcasting/browsing which was dropped in CUPS 1.6. Now remote
- printers appear as local print queues as before, but with the
- standardized Bonjour broadcasting.
- - "make dist" got broken in 1.0.25. Fixed.
-
-CHANGES IN V1.0.25
-
- - urftopdf: Newly added filter to convert the URF format which (at
- least some) iOS apps send when printing via AirPrint (Bug #1076).
- - pdftopdf: pdfautorotate functionality has been patched directly
- into pdftopdf (Bug #1080).
- - pdftopdf: "mirror" produced only empty pages (XObjects not there).
- - pdftopdf: Fixed segfault on "page-ranges=1-2147483647" (from cups).
- - pdftopdf: Fixed collate filler insertion.
- - texttopdf: Fixed deficient string escaping (Bug #1071).
- - pdftoopvp: Get correct byte order definition when building under
- OpenBSD (Bug #1070).
- - serial backend: Added check for sys/ioctl.h to configure.ac (Bug
- #1069).
- - pdftopdf: Made code building under OpenBSD (Bug #1068).
- - pdftopdf: Don't expect too much C++11 support for now (Bug #1067).
-
-CHANGES IN V1.0.24
-
- - pdftopdf now generates the necessary pdf comments to disable
- duplicate number-up when pdftops is also applied (Bug #1063).
- - pdftops: Added support for using Adobe Reader (acroread) in command
- line mode for turning PDF to PostScript (Bug #1065).
- - pdftopdf: Fix build on OpenBSD (Bug #1062).
- - pdftops: Fix stripping of page management options from the pstops
- command line which got already applied by pdftopdf. If the name
- of the option to be removed is contained in the name of a option
- in the command line (like "number-up" in "number-up-layout" or
- "scaling" in "Natural-scaling"), this option gets stripped instead
- of the correct option (Bug #1064).
-
-CHANGES IN V1.0.23
-
- - Removed filter/pdftopdf.old
- - Fixed the requires.private for cupsfilters lib
-
-CHANGES IN V1.0.22
-
- - Added missing *.h files of filter/pdftopdf/ to source file list so
- that "make dist" builds correct upstream tarballs.
-
-CHANGES IN V1.0.21
-
- - bannertopdf: Page duplication routine fixed.
- - bannertopdf: Fixed invalid output of a direct stream object.
- - pdftopdf filter replaced by new QPDF-based filter from Tobias
- Hoffmann's Google Summer of Code project. The former Poppler-based
- pdftopdf duplicated a lot of Poppler's code. The old filter is
- still in the package as pdftopdf.old with source code in
- filter/pdftopdf.old. It will be removed in a later release.
- - Added most recent contributors to AUTHORS and COPYING files.
-
-CHANGES IN V1.0.20
-
- - pdftops: Added another workaround for Kyocera printers: Some
- models get very slow on images which request interpolation,
- so now we remove the image interpolation requests by additional
- PostScript code only inserted for Kyocera printers (Ubuntu bug
- #1026974).
- - pdftops: The build system only configured the default renderer
- (Ghostscript OR Poppler), not the other renderer, but as we support
- switching on runtime both need to get configured.
- - Improved portability of the package to non-Linux systems (Bug #1056).
- - Made the Poppler-based filters pdftopdf and pdftoopvp build with
- both Poppler 0.18.x and 0.20.x (Bug #1055).
- - Let build system check for dlopen.
-
-CHANGES IN V1.0.19
-
- - Fixes according to Coverity scan results (Bug #1054).
- - Added distribution packaging instructions to INSTALL.
- - Switched build system to autotools. This especially fixes several
- build problems in Gentoo. Also build-tested with CUPS 1.6.0b1.
- - Fixes for compatibility with clang/gcc-4.7.
- - textonly: Filter did not work as a pipe with copies=1 (Bug #1032).
- - texttopdf: Avoid trimming the results of FcFontSort(), as this may
- miss some reasonable candidates under certain circumstances. BTW,
- fix passing a non-pointer as a pointer to "result" (Debian bug
- #670055),
- - Corrected documentation. The option for the maximum image rendering
- resolution in pdftops is "pdftops-max-image-resolution", not
- "pdftops-max-image-resolution-default".
-
-CHANGES IN V1.0.18
-
- - Modified "./configure" options related to the pdftops filter to
- allow changing the defaults for the renderer being used by default
- (Ghostscript or Poppler) and the maximum image rendering resolution
- and to supply paths for both Ghostscript's gs and Poppler's pdftops.
- - pdftops: Allow selection whether Ghostscript or Poppler is used
- at runtime, setting the "pdftops-renderer" option to "gs" or
- "pdftops".
- - pdftops: Allow setting an upper limit for the image rendering
- resolution, also at runtime, setting the option
- "pdftops-max-image-resolution" to the desired limit in dpi.
- "0" means no limit.
- - pdftops: Fixed crash by wrong usage of sizeof() function when adding
- "Collate" to the fifth command line argument for the "pstops" CUPS
- filter call (Ubuntu bug #982675).
- - pdftops: Removed newline from copies value when reading it from
- the "%%PDFTOPDFNumCopies" entry of the incoming PDF file.
- - pdftops: Silenced compiler warning about ignoring the return
- value of the write() function.
- - pdftops: Added a crash guard.
- - pdftops: Start determining the printing resolution with
- cupsRasterInterpretPPD(), this is the most reliable as often
- the choice names of the "Resolution" option are marketing names
- with higher numerical values than the actual resolution. Also
- ignore error exit values of cupsRasterInterpretPPD() as the
- function can error out after having found the resolution.
- - pdftops: If printing resolution is determined by
- cupsRasterInterpretPPD() do not stick on 100 dpi if the
- resolution cannot be determined (Ubuntu bug #984082).
-
-CHANGES IN V1.0.17
-
- - pdftopdf: Fixed segmentation fault when printing selected pages
- ("page-ranges" option, Ubuntu bug #980673).
-
-CHANGES IN V1.0.16
-
- - pdftopdf: Fixed segmentation faults when using N-up with certain PDF
- files (Ubuntu bug #980673) and when calling pdftopdf manually without
- specifyting a PPD file.
-
-CHANGES IN V1.0.15
-
- - pdftops: Suppress image compression only for Brother printers as they
- really need this measure to print at all. This accelerates printer-
- internal job processing on most other printers (tested on HP and
- Kyocera). Also suppress page compression on Kyocera printers, this
- works around a bug in Kyocera's PostScript interpreters which makes
- printing pages with images very slow (Ubuntu bug #977912).
-
-CHANGES IN V1.0.14
-
- - pdftops: Determine printing resolution from the PPD file and supply
- it on the Ghostscript or pdftops (Poppler) command line, so that
- the renderer does the image rendering with a resolution matching the
- printer's resolution. This avoids too slow processing of the jobs
- by the printer's built-in PostScript interpreter. In addition
- a default resolution of 300 dpi is used for PPDs without any hint
- of the printer's resolution, as most PostScript lasers use multiples
- of 300 dpi as resolution (Ubuntu bug #977912).
-
-CHANGES IN V1.0.13
-
- - bannertopdf: Fix display of the job dates on the test page and on
- banner pages (Ubuntu bug #975064).
-
-CHANGES IN V1.0.12
-
- - Fixed crash of imagetopdf filter when it is called manually
- without supplying a valid PPD file (Ubuntu bug #973564).
-
-CHANGES IN V1.0.11
-
- - Actually install the Generic PDF printer PPD file.
- - Really introduce a Generic PDF printer PPD file.
-
-CHANGES IN V1.0.10
-
- - Added Generic PPD file for native PDF printers.
- - Updated all code copied from Poppler to the current state of Poppler.
- - Made Poppler-based PDF filters building with various versions of
- Poppler.
-
-CHANGES IN V1.0.9
-
- - Deactivated NIME conversion rules which are not used by the PDF-
- based printing workflow.
- - Cleaned up sample PPD file HP-Color_LaserJet_CM3530_MFP-PDF.ppd.
- - imagetopdf: Added support for native PDF printers.
- - imagetopdf, imagetoraster: Let image input "scale to fit"
- by default. This makes photo printing via AirPrint work,
- as the iOS devices send JPEG but do not allow setting options.
-
-CHANGES IN V1.0.8
-
- - pdftops: Generally do not compress fonts and images, and
- also do not do CCITT compression for bitmap glyphs to make
- the PostScript output more compatible with buggy PostScript
- interpreters. The output gets 30-50% longer but will work on
- many more different printer models. Problems were also
- discovered on HP and not only on Brother (Ubuntu bug
- #960666).
-
-CHANGES IN V1.0.7
-
- - pdftops: Added PostScript debug mode. For jobs sent with "-o psdebug"
- the PostScript output by Ghostscript does not have compression of
- pages and fonts, so that one can analyse the PostScript code,
- especially in cases of incompatibilities and bugs of the built-in
- PostScript interpreters of printers. Thanks to the Ghostscript
- upstream developers for this hint.
-
-CHANGES IN V1.0.6
-
- - texttopdf: Fixed minor miscalculation of /AvgWidth.
- - texttopdf: Added support for direct file references in pdf.utf-8.
- - pdftops: Added another workaround for a bug in Brother's PostScript
- interpreter: Suppress CCITT compression for bitmap glyphs and
- images on Brother printers (Ubuntu bug #955553).
- - texttopdf: Fixed typo in pdf font descriptor dictionary keys.
- - Fixed ColorDevice definition in cupsfilters.drv for HP DesignJet
- printers.
- - Put ModelNumber entries in cupsfilters.drv at the right place to
- get correct "*cupsModelNumber:" entries in the PPDs for the HP
- DesignJet printers.
- - rastertopclx: Code of JCL options did not get inserted into the JCL
- header.
- - parallel backend: Use the same way as CUPS does to prevent an
- infinite loop on side channel errors (CUPS STR #4044).
- - pdftopdf: Added support for native PDF printers, add JCL (PJL)
- options and send page_log entries only if the PDF has the
- "*JCLToPDFInterpreter:" keyword.
- - Updated README.txt for the new native PDF printer support.
- - Added a sample PPD file for a native PDF printer,
- HP-Color_LaserJet_CM3530_MFP-PDF.ppd.
- - texttopdf: A lot of internal rework; also split up into more files
- - texttopdf: Fixed many bugs on the way
- - texttopdf: Added support for CFF-flavoured OTFs; for these
- subsetting is not yet implemented, full embedding is done instead
- - texttopdf: Adapted and improved fontconfig font selection
- - Make sure that "make clean" and "make distclean" also work if
- Makedefs does not exist (Debian bug #663564).
-
-CHANGES IN V1.0.5
-
- - pdftops: Added insertion of workaround PostScript code for printers
- with bugs in their PS interpreters (Ubuntu bugs #950713, #951627).
- - parallel backend: Break infinite loop (Ubuntu bug #936647).
- - texttopdf: Complete the implementation of fontconfig-based font
- selection (Debian bug #663070).
-
-CHANGES IN V1.0.4
-
- - texttopdf: Fall back to altermative fonts via fontconfig if the
- FreeMono TrueType fonts are not installed (Debian bugs #495598
- and #662660).
- - bannertopdf: Fix off-by-one error in page duplication
- - bannertopdf: Put indirect references to streams into the page's
- contents
- - bannertopdf: Let byte offsets for the Xref table of the PDF output
- being determined correctly also when the output goes to stdout
- (Ubuntu bug #939735).
- - bannertopdf: Output multiple copies of the test page if duplex
- and/or N-up is chosen, to let the test page appear on all possible
- positions of the sheet (Ubuntu bug #939530).
-
-CHANGES IN V1.0.3
-
- - bannertopdf: Draw the frame to mark the non-printable borders 1pt
- smaller all around to assure that it is always visible, like it was
- done in bannertops.
- - bannertopdf: Scale the page to fit onto the desired output page.
- - bannertopdf: Get and output the correct media limits.
-
-CHANGES IN V1.0.2
-
- - bannertopdf: Fixed crash caused by wrong Poppler API use.
- - bannertopdf: Info text on test page came out in gray and not in
- black.
-
-CHANGES IN V1.0.1
-
- - Added the textonly filter and its PPD file, a driver for text-only
- printers.
- - Install the pdftoijs sample PPD file
- HP-PhotoSmart_Pro_B8300-hpijs-pdftoijs.ppd
- - Added cupsfilters.drv, centralized ppdc-based PPD generator for the
- printer driver filters in this package. Current printers supported
- are several HP DesignJet large format inkjet printers.
- - Fixed "make uninstall". Now everything of this package gets removed.
- - Added wrapper scripts texttops and imagetops for backward
- compatibility to third-party PPD files or custom configurations
- which refer to these filters explicitly (Debian bug #658258).
-
-CHANGES IN V1.0
-
- - Built the pdftops filter based on Ghostscript by default, as
- Ghostscript is better optimized for print output (Ubuntu bug
- #926068).
- - If the pdftops filter is built for using Poppler, let Poppler not
- emit PostScript level 3, as this causes problems with some HP
- printers (Ubuntu bug #277404, Freedesktop (Poppler) bug #19640).
- - bannertopdf needs to be linked with C++ (bug #995)
- - Added test.sh script for testing texttopdf
- - Added original documentation of the PDF filters to README.txt
- - Install C header files and the static library
- - General clean-up of "make install" targets in Makefiles
- - Raised MIME conversion cost factor of pdftoraster from 66 to 100 to
- give priority to the gstoraster filter from Ghostscript, as this
- filter supports ICC-profile-based color management.
- - Documentation updated because libijs, liblcms, freetype, and
- fontconfig are needed to build this package
-
-CHANGES IN V1.0b1
-
- - Removed the bannertops, imagetops, and texttops filters, they are
- not needed any more in the PDF-based printing workflow
- - Added support for liblcms2
- - Named the package "OpenPrinting CUPS Filters"

-INTRODUCTION
-
- CUPS is a standards-based, open source printing system used by
- Apple's Mac OS® X and other UNIX®-like operating systems,
- especially also Linux. CUPS uses the Internet Printing Protocol
- ("IPP") and provides System V and Berkeley command-line
- interfaces, a web interface, and a C API to manage printers and
- print jobs.
-
- This package contains backends, filters, and other software that
- was once part of the core CUPS distribution, but during the time
- when CUPS was developed at Apple, Apple stopped maintining these
- parts as they were not needed by Mac OS.
-
- In addition it contains more filters and software developed
- independently of Apple, especially filters for the PDF-centric
- printing workflow introduced by OpenPrinting and a daemon to
- browse broadcasts of remote CUPS printers and IPP printers to make
- them available locally.
-
- Since CUPS 1.6.0 cups-filters is required for using printer
- drivers (and also driverless printing) with CUPS under Linux. This
- version of cups-filters is only for CUPS 2.2.2 or newer. Please
- use the cups-filters 1.x line for older CUPS versions.
-
- For compiling and using this package CUPS (2.2.2 or newer),
- libqpdf (10.3.2 or newer), libjpeg, libpng, libtiff, freetype,
- fontconfig, liblcms (liblcms2 recommended), libavahi-common,
- libavahi-client, libdbus, and glib are needed. It is highly
- recommended, especially if non-PDF printers are used, to have at
- least one of Ghostscript (preferred), Poppler, or MuPDF.
-
- It also needs gcc (C compiler), automake, autoconf, autopoint, and
- libtool. On Debian, Ubuntu, and distributions derived from them
- you could also install the "build-essential" package to
- auto-install most of these packages.
-
- If Ghostscript is used (via the "gsto..." or the "universal" CUPS
- filters), Ghostscript 10.00.0 is required (10.01.0 is highly
- recommended) and it has to be built at least with the "pdfwrite",
- "ps2write", "cups", "pwgraster", "appleraster", "pclm", "pclm8",
- "pdfimage24", "pdfimage8", "pxlcolor", and "pxlmono" output
- devices. libcups of CUPS 2.2.2 or newer is required to buid
- Ghostscript this way.
-
- The Poppler-based pdftoraster filter needs a C++ compiler which
- supports C++11 and Poppler being built with the "./configure"
- option "-DENABLE_CPP=ON" for building the C++ support library
- libpoppler-cpp. This is the case for most modern Linux
- distributions.
-
- If you use MuPDF as PDF renderer make sure to use at least version
- 1.15, as the older versions have bugs and so some files get not
- printed correctly.
-
- For Braille embosser support (see below) you will also need at
- least liblouis, ImageMagick, and poppler-utils. Recommended is to
- also have liblouisutdml, antiword, docx2txt for more sophisticated
- Braille generation representing also the formatting of the input
- text. None of these is needed for compiling cups-filters.
-
- CUPS, this package, and Ghostscript contain some rudimentary
- printer drivers and especially the filters needed for driverless
- printing (currently PWG Raster, Apple Raster, PCLm, and PDF output
- formats, for printers supporting IPP Everywhere, AirPrint, Wi-Fi
- Direct, and other standards). See
- http://www.openprinting.org/drivers/ for a more comprehensive set
- of printer drivers for Linux.

+fontconfig, liblcms (liblcms2 recommended), libavahi-common,
+libavahi-client, libdbus, and glib are needed. It is highly
+recommended, especially if non-PDF printers are used, to have at
+least one of Ghostscript (preferred), Poppler, or MuPDF.
+
+It also needs gcc (C compiler), automake, autoconf, autopoint, and
+libtool. On Debian, Ubuntu, and distributions derived from them
+you could also install the "build-essential" package to
+auto-install most of these packages.
+
+If Ghostscript is used (via the "gsto..." or the "universal" CUPS
+filters), Ghostscript 10.00.0 is required (10.01.0 is highly
+recommended) and it has to be built at least with the "pdfwrite",
+"ps2write", "cups", "pwgraster", "appleraster", "pclm", "pclm8",
+"pdfimage24", "pdfimage8", "pxlcolor", and "pxlmono" output
+devices. libcups of CUPS 2.2.2 or newer is required to build
+Ghostscript this way.
+
+The Poppler-based pdftoraster filter needs a C++ compiler which
+supports C++11 and Poppler being built with the "./configure"
+option "-DENABLE_CPP=ON" for building the C++ support library
+libpoppler-cpp. This is the case for most modern Linux
+distributions.
+
+If you use MuPDF as PDF renderer make sure to use at least version
+1.15, as the older versions have bugs and so some files get not
+printed correctly.
+
+For Braille embosser support (see below) you will also need at
+least liblouis, ImageMagick, and poppler-utils. Recommended is to
+also have liblouisutdml, antiword, docx2txt for more sophisticated
+Braille generation representing also the formatting of the input
+text. None of these is needed for compiling cups-filters.
+
+CUPS, this package, and Ghostscript contain some rudimentary
+printer drivers and especially the filters needed for driverless
+printing (currently PWG Raster, Apple Raster, PCLm, and PDF output
+formats, for printers supporting IPP Everywhere, AirPrint, Wi-Fi
+Direct, and other standards). See
+http://www.openprinting.org/drivers/ for a more comprehensive set
+of printer drivers for Linux.

-IMAGE PRINTING DEFAULT CHANGED TO "SCALE TO FIT"
-
- Compared to the PostScript-based original CUPS filters there is a
- change of defaults: The imagetopdf and imagetoraster filters print
- in "scale-to-fit" mode (image is scaled to fill one page but
- nothing of the image being cut off) by default.
-
- This is done to support photo printing via AirPrint. The photo
- apps on Apple's iOS devices send print jobs as JPEG images and do
- not allow to set any options like "scaling" or the page size. With
- "scale-to-fit" mode set by default, the iOS photos come out on one
- page, as expected.
-
- To get back to the old behavior, supply one of the options
- "nofitplot" "filplot=Off", "nofit-to-page", or "fit-to-page=Off".
-
-GHOSTSCRIPT RENDERING OF FILLED PATHS
-
- When Ghostscript is rendering PostScript or PDF files into a
- raster format the filled paths are ususally rendered with the
- any-part-of-pixel method as it is PostScript standard. On
- low-resolution printers, like label printers with 203 dpi,
- graphics output can get inaccurate and so for example bar codes do
- not work any more. This problem can be solved by letting
- Ghostscript use the center-of-pixel method.
-
- This can be done by either supplying the option "-o
- center-of-pixel" or "-o CenterOfPixel" on the command line when
- printing or by adding a "CenterOfPixel" option to the PPD file and
- set it to "true", for example by adding the following lines to the
- PPD file of the print queue (usually in /etc/cups/ppd/):
-
- *OpenUI *CenterOfPixel/Center Of Pixel: PickOne
- *OrderDependency: 20 AnySetup *CenterOfPixel
- *DefaultCenterOfPixel: true
- *CenterOfPixel true/true: ""
- *CenterOfPixel false/false: ""
- *CloseUI: *CenterOfPixel
-
- This option can be used when the print queue uses the gstoraster
- filter.
-
-POSTSCRIPT PRINTING RENDERER AND RESOLUTION SELECTION
-
- If you use CUPS with this package and a PostScript printer then
- the included pdftops filter converts the print job data which is
- in PDF format into PostScript. By default, the PostScript is
- generated with Ghostscript's "ps2write" output device, which
- generates a DSC-conforming PostScript with compressed embedded
- fonts and compressed page content. This is resource-saving and
- leads to fast wire transfer of print jobs to the printer.
-
- Unfortunately, Ghostscript's PostScript output is not compatible
- with some printers due to interpreter bugs in the printer and in
- addition, processing (by Ghostscript or by the printer's
- interpreter) can get very slow with high printing resolutions when
- parts of the incoming PDF file are converted to bitmaps if they
- contain graphical structures which are not supported by
- PostScript. The bitmap problem especially occurs on input files
- with transparency, especially also the ones produced by Cairo
- (evince and many other GNOME/GTK applications) which unnecessarily
- introduces transparency even if the input PDF has no transparency.
-
- Therefore there are two possibilities to configure pdftops at
- runtime:
-
- 1. Selection of the renderer: Ghostscript, Poppler, pdftocairo,
- Adobe Reader, or MuPDF
-
- Ghostscript has better color management and is generally optimized
- more for printing. Poppler produces a PostScript which is
- compatible with more buggy built-in PostScript interpreters of
- printers and it leads to a somewhat quicker workflow when
- graphical structures of the input PDF has to be turned into
- bitmaps. Adobe Reader is the PDF renderer from Adobe, the ones who
- created PDF and PostScript. pdftocairo is a good choice for the
- PDF output of Cairo (for example when printing from evince). It
- is less resource-consuming when rasterizing graphical elements
- which cannot be represented in PostScript (like
- transparency). Note that pdftocairo only supports PDF input using
- DeviceRGB, DeviceGray, RGB or sGray and is not capable of
- generating PostScript level 1. So its support is only experimental
- and distributions should not choose it as default.
-
- The selection is done by the "pdftops-renderer" option, setting it
- to "gs", "pdftops", "pdftocairo", "acroread", "mupdf", or "hybrid":
-
- Per-job: lpr -o pdftops-renderer=pdftops ...
- Per-queue default: lpadmin -p printer -o pdftops-renderer-default=gs
- Remove default: lpadmin -p printer -R pdftops-renderer-default
-
- By default, pdftops uses Ghostscript if this does not get changed
- at compile time, for example by the Linux distribution vendor.
-
- Hybrid means Ghostscript for most printers, but Poppler's pdftops
- for Brother, Minolta, and Konica Minolta. Printer make and model
- information comes from the PPD or via the "make-and-model" option.
-
- 2. Limitation of the image rendering resolution
-
- If graphical structures of the incoming PDF file have to be
- converted to bitmaps due to limitations of PostScript, the
- conversion of the file by pdftops or the rendering by the printer
- can get too slow if the bitmap resolution is too high or the
- printout quality can degrade if the bitmap resolution is too low.
-
- By default, pdftops tries to find out the actual printing
- resolution and sets the resolution for bitmap generation to the
- same value. If it cannot find the printing resolution, it uses 300
- dpi. It never goes higher than a limit of 1440 dpi. Note that this
- default limit can get changed at compile time, for example by the
- Linux distribution vendor.
-
- The resolution limit for bitmaps can be changed to a lower or
- higher value, or be set to unlimited. This is done by the option
- "pdftops-max-image-resolution", setting it to the desired value
- (in dpi) or to zero for unlimited. It can be used per-job or as
- per-queue default as the "pdftops-renderer" option described
- above.
-
- The "pdftops-max-image-resolution" option is ignored when Adobe
- Reader is selected as PDF renderer.
+See the "COPYING", "LICENCE", and "NOTICE" files for legal
+information. The license is the same as for CUPS, for a maximum of
+compatibility.

POSTSCRIPT PRINTING DEBUG MODE
- Sometimes a PostScript printer's interpreter errors, crashes, or
- somehow else misbehaves on Ghostscript's output. To find
- workarounds (currently we have already workarounds for Brother and
- Kyocera) it is much easier to work with uncompressed PostScript.
- To get uncompressed PostScript as output, send a job with the
- "psdebug" option, with commands like the following:

-HELPER DAEMON FOR BROWSING REMOTE CUPS PRINTERS AND IPP NETWORK PRINTERS
-
- From version 1.6.0 on in CUPS the CUPS broadcasting/browsing
- facility was dropped, in favour of Bonjour-based broadcasting of
- shared printers. This is done as Bonjour broadcasting of shared
- printers is a standard, established by the PWG (Printing Working
- Group, http://www.pwg.org/), and most other network services
- (shared file systems, shared media files/streams, remote desktop
- services, ...) are also broadcasted via Bonjour.
-
- Problem is that CUPS only broadcasts its shared printers but does
- not browse broadcasts of other CUPS servers to make the shared
- remote printers available locally without any configuration
- efforts. This is a regression compared to the old CUPS
- broadcasting/browsing. The intention of CUPS upstream is that the
- application's print dialogs browse the Bonjour broadcasts as an
- AirPrint-capable iPhone does, but it will take its time until all
- toolkit developers add the needed functionality, and programs
- using old toolkits or no toolkits at all, or the command line stay
- uncovered.
-
- The solution is cups-browsed, a helper daemon running in parallel
- to the CUPS daemon which listens to Bonjour broadcasts of shared
- CUPS printers on remote machines in the local network via Avahi,
- and can also listen for (and send) CUPS Browsing broadcasts. For
- each reported remote printer it creates a local raw queue pointing
- to the remote printer so that the printer appears in local print
- dialogs and is also available for printing via the command
- line. As with the former CUPS broadcasting/browsing with this
- queue the driver on the server is used and the local print dialogs
- give access to all options of the server-side printer driver.
-
- Note that CUPS broadcasting/browsing is available for legacy
- support, to let the local CUPS daemon work seamlessly together
- with remote CUPS daemons of version 1.5.x and older which only
- support CUPS broadcasting/browsing. In networks with only CUPS
- 1.6.x servers (or Ubuntu or Fedora/Red Hat servers with CUPS
- 1.5.x) please use the native Bonjour broadcasting of your servers
- and cups-browsed, configured for Bonjour browsing only on the
- clients.
-
- Also high availability with redundant print servers and load
- balancing is supported. If there is more than one server providing
- a shared print queue with the same name, cups-browsed forms a
- cluster locally with this name as queue name and printing through
- the "implicitclass" backend. Each job triggers cups-browsed to
- check which remote queue is suitable for the job, meaning that it
- is enabled, accepts jobs, and is not currently printing. If none
- of the remote queues fulfills these criteria, we check again in 5
- seconds, until a printer gets free to accommodate the job. When we
- search for a free printer, we do not start at the first in the
- list, but always on the one after the last one used (as CUPS also
- does with classes), so that all printer get used, even if the
- frequency of jobs is low. This is also what CUPS formerly did with
- implicit classes. Optionally, jobs can be sent immediately into
- the remote queue with the lowest number of waiting jobs, so that
- no local queue of waiting jobs is built up.
-
- For maximum security cups-browsed uses IPPS (encrypted IPP)
- whenever possible.
-
- In addition, cups-browsed is also capable of discovering IPP
- network printers (native printers, not CUPS queues) with known
- page description languages (PWG Raster, Apple Raster, PDF,
- PostScript, PCL XL, PCL 5c/e) in the local network and auto-create
- print queues with auto-created PPD files. This functionality is
- primarily for mobile devices running CUPS to not need a printer
- setup tool nor a collection of printer drivers and PPDs.
-
- cups-browsed can also be started on-demand, for example to save
- resources on mobile devices. For this, cups-browsed can be set
- into an auto shutdown mode so that it stops automatically when it
- has no remote printers to take care of any more, especially if an
- on-demand running avahi-daemon stops. Note that CUPS must stay
- running for cups-browsed removing its queues and so being able to
- shut down. Ideal is if CUPS stays running another 30 seconds after
- finishing its last job so that cups-browsed can take down the
- queue. For how to set up and control this mode via command line,
- configuration directives, or sending signals see the man pages
- cups-browsed(8) and cups-browsed.conf(5).
-
- The configuration file for cups-browsed is
- /etc/cups/cups-browsed.conf. This file can include limited forms
- of the original CUPS BrowseRemoteProtocols, BrowseLocalProtocols,
- BrowsePoll, and BrowseAllow directives. It also can contain the
- new CreateIPPPrinterQueues to activate discovering of IPP network
- printers and creating PPD-less queues for them.
-
- Note that cups-browsed does not work with remote CUPS servers
- specified by a client.conf file. It always connects to the local
- CUPS daemon by setting the CUPS_SERVER environment variable and so
- overriding client.conf. If your local CUPS daemon uses a
- non-standard domain socket as only way of access, you need to
- specify it via the DomainSocket directive in
- /etc/cups/cups-browsed.conf.
-
- The "make install" process installs init scripts which make the
- daemon automatically started during boot. You can also manually
- start it with (as root):
+and print into this queue as described above. The PostScript
+output is in /tmp/printout after the job has completed.
+
+This option does not change anything if Poppler's pdftops is used

}
soft_copies = device_copies > 1 ? 1 : Copies;
+```
-7.2 JCL
+6.2 JCL
When you print PDF files to a PostScript(PS) printer, you can specify
device options in PS. In this case, you can write PS commands in a PPD file
like as follows.
+```
*OpenUI *Resolution/Resolution : PickOne
*DefaultResolution: 600
*Resolution 300/300 dpi: "<</HWResolution[300 300]>>setpagedevice"
*Resolution 600/600 dpi: "<</HWResolution[600 600]>>setpagedevice"
*CloseUI: *Resolution
+```
However, if options cannot be described in PS file, you can write JCLs
as follows;
+```
*JCLOpenUI *JCLFrameBufferSize/Frame Buffer Size: PickOne
*DefaultJCLFrameBufferSize: Letter
*OrderDependency: 20 JCLSetup *JCLFrameBufferSize
*JCLFrameBufferSize Letter: '@PJL SET PAGEPROTECT = LTR<0A>'
*JCLFrameBufferSize Legal: '@PJL SET PAGEPROTECT = LGL<0A>'
*JCLCloseUI: *JCLFrameBufferSize
+```
Because PDF cannot specify device options in a PDF file, you have to define
all the device options as JCLs.
So, "imagetopdf" handles this case as follows;
(In following pseudo program, JCL option is an option specified with JCLOpenUI)
+```
if (Both JCLBegin and JCLToPSInterpreter are specified in the PPD file) {
output JCLs that marked JCL options.
}
}
}
output NEWLINE
+```
Thus, if you want to use both PDF filters and GS by single PPD file,
what you should do is to add the following line in the PPD file;
+```
*pdftopdfJCLBegin: "pdfto... jobInfo:"
+```
Replace "pdfto..." by the name of the actual filter to be called after
pdftopdf.
For example, if the page size is defined in a PPD file as following;
- *OpenUI *PageSize/Page Size: PickOne
- *DefaultPageSize: A4
- *PageSize A4/A4:
- *PageSize Letter/US Letter:
- *CloseUI: *PageSize
+ *OpenUI *PageSize/Page Size: PickOne
+ *DefaultPageSize: A4
+ *PageSize A4/A4:
+ *PageSize Letter/US Letter:
+ *CloseUI: *PageSize
if you choose the page size "Letter", the string "PageSize=Letter;" is
added to jobInfo. On the other hand, if the driver requires the different
instead of "PageSize=Letter;" as the jobInfo value, the PPD file has to
be defined as following;
- *OpenUI *PageSize/Page Size: PickOne
- *DefaultPageSize: A4
- *PageSize A4/A4:
- *pdftopdfJCLPageSize A4/A4: "PS=A4;"
- *PageSize Letter/US Letter:
- *pdftopdfJCLPageSize Letter/US Letter: "PS=LT;"
- *CloseUI: *PageSize
+ *OpenUI *PageSize/Page Size: PickOne
+ *DefaultPageSize: A4
+ *PageSize A4/A4:
+ *pdftopdfJCLPageSize A4/A4: "PS=A4;"
+ *PageSize Letter/US Letter:
+ *pdftopdfJCLPageSize Letter/US Letter: "PS=LT;"
+ *CloseUI: *PageSize
-7.3 Temporally files location
+6.3 Temporally files location
"imagetopdf" creates temporally files if needed. Temporary files are created
in the location specified by TMPDIR environment variable. Default location
is "/tmp".
-PDFTOPDF
-========
+### PDFTOPDF
The pdftopdf filter depends on libqpdf to read and write PDF files.
A similar filter (which can serve as behavior reference)
is called "cgpdftopdf" in OS X (not open source).
-Command line
-------------
+
+#### Command line
pdftopdf follows the usual CUPS filter calling conventions, i.e.
- pdftopdf <job> <user> <title> <num-copies> <options> [<filename>]
+ pdftopdf <job> <user> <title> <num-copies> <options> [<filename>]
together with the environment variables "PPD" and "CLASSIFICATION".
pdftopdf processes the following standard command-line and/or PPD options:
-Copies # ppd will only override, when commandline parameter was 1
-fitplot / fit-to-page / ipp-attribute-fidelity
-landscape / orientation-requested
-PageSize / page-size / MediaSize / media-size
-page-left / page-right / page-bottom / page-top
-media-top-margin / media-left-margin / media-right-margin / media-bottom-margin
-Duplex / JCLDuplex / EFDuplex / JD03Duplex / sides
-number-up / number-up-layout
-page-border
-OutputOrder / OutputBin / DefaultOutputOrder / page-delivery
-page-label
-page-set
-page-ranges
-MirrorPrint / mirror
-emit-jcl
-position
-Collate / multiple-document-handling / sheet-collate
-cupsEvenDuplex
-cupsManualCopies # via ppd
+ Copies # ppd will only override, when commandline parameter was 1
+ fitplot / fit-to-page / ipp-attribute-fidelity
+ landscape / orientation-requested
+ PageSize / page-size / MediaSize / media-size
+ page-left / page-right / page-bottom / page-top
+ media-top-margin / media-left-margin / media-right-margin /
+ media-bottom-margin
+ Duplex / JCLDuplex / EFDuplex / JD03Duplex / sides
+ number-up / number-up-layout
+ page-border
+ OutputOrder / OutputBin / DefaultOutputOrder / page-delivery
+ page-label
+ page-set
+ page-ranges
+ MirrorPrint / mirror
+ emit-jcl
+ position
+ Collate / multiple-document-handling / sheet-collate
+ cupsEvenDuplex
+ cupsManualCopies # via ppd
Additional (non-standard) options
----------------------------------
1) Booklet printing
- booklet=Off/On/Shuffle-Only
+ booklet=Off/On/Shuffle-Only
"On" also tries to set DuplexTumble (two-sided-short-edge) and forces number-up=2
- booklet-signature=(multiple of 4, or default: -1 to use "all pages")
+ booklet-signature=(multiple of 4, or default: -1 to use "all pages")
2) Page autorotate
instead of (e.g. fitplot) scaling them down unrotated.
This behavier can be controlled by
- pdfAutorotate / nopdfAutorotate
+ pdfAutorotate / nopdfAutorotate
Specifically, if a PDF file contains pages with page width greater than
page height (a landscape page), such pages are automatically rotated
"*LandscapeOrientation: Minus90". In this case, clockwise rotation is used.
To turn off the feature on a job-by-job basis use
- lp -d <print_queue_name> -o nopdfAutorotate <document>
+
lp -d <print_queue_name> -o nopdfAutorotate <document>
On a per-queue basis use
- -o nopdfAutorotate-default
+ -o nopdfAutorotate-default
as an option to lpadmin.
form stays unflattened and so the filled in data will possibly not get
printed.
-Native PDF Printer / JCL Support
---------------------------------
+
+#### Native PDF Printer / JCL Support
Note that for most modern native PDF printers JCL is not needed any
more as they are controlled via IPP. For these the PPD files get
This enables for hardware copy generation and device collate; e.g. with PJL:
-*JCLBegin: "<1B>%-12345X@PJL JOB<0A>"
-*JCLToPDFInterpreter: "@PJL ENTER LANGUAGE = PDF <0A>"
-*JCLEnd: "<1B>%-12345X@PJL EOJ <0A><1B>%-12345X"
+ *JCLBegin: "<1B>%-12345X@PJL JOB<0A>"
+ *JCLToPDFInterpreter: "@PJL ENTER LANGUAGE = PDF <0A>"
+ *JCLEnd: "<1B>%-12345X@PJL EOJ <0A><1B>%-12345X"
For each marked option, the prefixed "pdftopdfJCL<option name>" keywords
can also be used to send raw JCL strings for that option.
Other JCL code can be injected via "*JCLOpenUI: ..." ... "*JCLCloseUI: ...".
-Special PDF comments
---------------------
+
+#### Special PDF comments
pdftopdf adds comments to the pdf preamble that might esp. be of use
to subsequent filters, e.g.
The "NumCopies" and "Collate" values refer to the expected device/hardware
copies, i.e. when pdftopdf's soft-copy generation did not handle this options.
-Limitations
------------
+
+#### Limitations
pdftopdf does not support functions that are not related to printing
features, including interactive features and document interchange features.
Many of these operators and sections are just ignored.
Some of these may be output, but those functions are not assured.
-Most notable is the use of AcroForms; their content will not be printed
-if any non-trivial processing by pdftopdf is involved (e.g. "fitplot").
-This only occurs when a file is printed directly, e.g. by "lpr".
-Usual PDF viewer applications (xpdf, evince, acroread, ghostscript, ...)
-will hardcopy the form content into printable pdf operations,
-when choosing to print such a document.
-
-Known issues
-------------
+#### Known issues
- Borders, esp. in the "number-up=1 fitplot=false"-case might be drawn
at incorrect locations.
- Missing AcroForm-content might surprise users printing PDF files directly /
from the command-line (see the Limitations section, above).
-License
--------
-
-pdftopdf is released under the MIT license.
-The required libqpdf is available under version 2.0 of the Apache License,

-URFTOPDF
-========
-
-"urftopdf" is a filter to convert Apple's proprietary URF raster
-format into PDF. URF raster is generated by some iOS applications when
-printing via Airprint, so this filter provides a more complete support
-for AirPrint clients. Note that it is not clear whether nowadays all
-iOS applications send PDF and not URF any more. Also the filter does
-not support all variants of URF format so the URF support is most
-probably incomplete.
-
-Apple does not provide any official documentation of the format but there is
-already some reverse engineering done. A description of the format as far as it
-got found out and two sample files can be found here:

-BEH - Backend Error Handler wrapper backend
-===========================================
+### BEH - Backend Error Handler wrapper backend
A wrapper for CUPS backends to make error handling more configurable
Activate "beh" for your print queue(s) with command(s) like this:
-lpadmin -p <queue name> -E -v beh:/<dd>/<att>/<delay>/<originaluri>
-
-with
- <queue name>: The name of your print queue
- <dd>: Don't Disable, if "1", beh always exits with zero
- status, so the queue gets never disabled when the
- original backend exits with an error. "0" carries
- the error status of the last call of the backend
- (after <att> retries) on to CUPS, so the queue
- usually gets disabled.
- <att>: Attempts, number of attempts to recall the backend
- in case of an error. "0" means infinite retries. In
- this case <dd> gets meaningless.
- <delay>: Delay between two attempts to call the beckend, to
- be given in seconds and as an integer number.
- Meaningless if <att> is one.
- <originaluri>: The original URI, which your queue had before. Can
- be determined with "lpstat -v".

All parameters, especially, <dd>, <att>, and <delay> have always to be
specified, even if one of them is meaningless due to the setting of
Example URIs:
-beh:/1/3/5/socket://printer:9100
+ beh:/1/3/5/socket://printer:9100
- On the network printer with host name "printer" it is tried to
- access 3 times with 5 second delays between the attempts. If the job
- still fails, the queue is not disabled (and the job discarded).

- printer comes back, in intervals of one minute. This way the job
- does not get lost when the printer is turned off and one can
- intendedly delay printing by simply switching off the printer. The
- ideal configuration for desktop printers and/or home users.

Originally this backend was written in Perl and part of the
foomatic-filters package. It was not overtaken into cups-filters
cups-filters without introducing new dependencies.
-BRAILLE EMBOSSING
-=================
+### BRAILLE EMBOSSING
cups-filters also provides filters and drivers for braille
embossers. It supports:
in the standard printer panel, or passed as -o options to the lp command.
-------------
-Text support
-------------
+#### Text support
Text can be embossed either with no translation on the computer side (the
embosser will translate), or with translation on the computer side (thanks to
liblouis). It is a matter of running
-lp file.txt
+ lp file.txt
or even
-lp file.html
-lp file.odt
-lp file.doc
-lp file.rtf
-lp file.docx
-lp file.pdf
+ lp file.html
+ lp file.odt
+ lp file.doc
+ lp file.rtf
+ lp file.docx
+ lp file.pdf
Important: it is really preferrable to directly print the document files
themselves, and not a pdf output, or printing from the application (which
quality.
---------------------
-Vector Image support
---------------------
+#### Vector Image support
Vector images can be embossed by converting them to braille dots.
which has to reconstruct lines to be embossed.
--------------
-Image support
--------------
+#### Image support
Images can be embossed by converting them to braille dots.
A lot of images formats are support, so one can just run
-lp file.png
-lp file.gif
-lp file.jpg
-...
+ lp file.png
+ lp file.gif
+ lp file.jpg
+ ...
Here are complete examples for controlling the processing (all options can be
omitted, the default values are shown here):
Emboss the image without edge detection, as black on white or white on black:
-lp -o "Edge=None" file.png
-lp -o "Edge=None Negate" file.png
+ lp -o "Edge=None" file.png
+ lp -o "Edge=None Negate" file.png
Emboss the image with edge detection, the default tuning parameters are set
here:
-lp -o "Edge=Edge EdgeFactor=1" file.png
-lp -o "Edge=Canny CannyRadius=0 CannySigma=1 CannyLower=10 CannyUpper=30" file.png
+ lp -o "Edge=Edge EdgeFactor=1" file.png
+ lp -o "Edge=Canny CannyRadius=0 CannySigma=1 CannyLower=10 CannyUpper=30" file.png
Emboss the image as it is, without any resize or edge detection, as black on
white or white on black:
-lp -o "nofitplot Edge=None" file.png
-lp -o "nofitplot Edge=None Negate" file.png
+ lp -o "nofitplot Edge=None" file.png
+ lp -o "nofitplot Edge=None Negate" file.png
-------------------------
-Generic embosser support
-------------------------
+
+#### Generic embosser support
It should be possible to make all embossers use the generic driver. For this to
work, one has to:
be distorted by the Braille interline spacing.
------------------------
-Index embossers support
------------------------
+#### Index embossers support
Supported models:
-Basic-S V3/4
-Basic-D V3/4
-Everest-D V3/4
-4-Waves PRO V3
-4X4 PRO V3
-Braille Box V4
+- Basic-S V3/4
+- Basic-D V3/4
+- Everest-D V3/4
+- 4-Waves PRO V3
+- 4X4 PRO V3
+- Braille Box V4
Index V3 embosser support has been well tested. It supports both text and
graphics mode. Embossers with firmware 10.30 and above can be easily configured
The density of dots for images can easily be chosen from the command line, for
instance:
-lp -o "GraphicDotDistance=160" file.png
+ lp -o "GraphicDotDistance=160" file.png
to select 1.6mm dots spacing
10.30 or above, or select the 10.20 firmware version in the "index" panel of the
cups printer options.
-----------------------
-Braille output options
-----------------------
+
+#### Braille output options
The output can be finely tuned from the standard printing panel, or from the
command-line, the following example selects translation tables for French and
Greek, with 2.5mm dot spacing and 5mm line spacing. All options can be omitted,
the default values are shown here.
-lp -o "LibLouis=fr-fr-g1 LibLouis2=gr-gr-g1 TextDotDistance=250 LineSpacing=500" file.txt
+ lp -o "LibLouis=fr-fr-g1 LibLouis2=gr-gr-g1 TextDotDistance=250 LineSpacing=500" file.txt
----------------------------------
-Reworking output before embossing
----------------------------------
+#### Reworking output before embossing
One may want to check and modify the .brf or .ubrl output before sending it to
the embosser. This can be achieved by first generating the .brf file:
lp -o document-format=image/vnd.cups-ubrl ~/test.ubrl
----------------
-BRF file output
----------------
+#### BRF file output
One can generate BRF files by adding a virtual BRF printer.
subdirectory of the home directory.
-----------------
-UBRL file output
-----------------
+#### UBRL file output
One can generate Unicode braille files, not useful for embossing, but which can
be easily looked at by sighted people to check for the output.
subdirectory of the home directory.
-----------------------------
-Remark about the source code
-----------------------------
+#### Remark about the source code
The file filter/braille/drivers/index/ubrlto4dot.c is used to generate
the translation table in
generation in the Makefile is more tedious than really useful.

+#### TODO
- Test whether one wants to negate, e.g. to emboss as few dots as possible
- textubrltoindex when liblouis tools will be able to emit 8dot braille
