36 <P>CUPS 1.2 includes many new features from the 1.0.x releases.
40 <H3><CODE>imagetoraster</CODE>, <CODE>imagetops</CODE></H3>
42 <P>The image file filters have been upgraded to support conversion of
43 Microsoft Bitmap ("BMP") and Alias PIX files.
47 <P>A new pdftops filter has been developed that is based on the
48 excellent Xpdf 0.90 software from Derek B. Noonburg. The new filter is
49 faster, smaller, and considerably more reliable than the
50 Ghostscript-based filter in CUPS 1.0.
54 <P>The <CODE>pstoraster</CODE> filter has been integrated with GNU
55 GhostScript 5.50. The new RIP supports most Level 3 PostScript language
58 <H3>rastertoepson</H3>
60 <P>The new <CODE>rastertoepson</CODE> filter supports EPSON printers
61 using the ESC/P or ESC/P2 command sets. PPDs are supplied for 9-pin,
62 24-pin, Stylus Color, and Stylus Photo printers.
64 <H2>User-Defined Printers and Options</H2>
66 <P>The new <CODE>lpoptions</CODE> command allows users to configure default
67 document options and create additional "instances" of existing printers,
68 each with unique options.
70 <P>The <CODE>lp</CODE>, <CODE>lpr</CODE>, and <CODE>lpstat</CODE> commands
71 have been upgraded to use this option and printer instance information
76 <P>CUPS 1.2 includes two new daemons that provide enhanced network printing
81 <P>The <CODE>cups-lpd</CODE> daemon provides support for clients using the
82 Line Printer Daemon protocol.
86 <P>The <CODE>cups-polld</CODE> daemon provides remote polling services for
91 <P>CUPS 1.2 includes several new printing commands.
95 <P>The <CODE>lpoptions</CODE> command provides user-defined printers and
100 <P>The <CODE>lpmove</CODE> command moves a print job to a new destination.
104 <P>The <CODE>lpinfo</CODE> command lists the available PPD files or devices.
106 <H2>IPP Implementation</H2>
108 <P>CUPS 1.2 adds support for the <CODE>set-job-attributes</CODE>
109 extension operation as well as two new CUPS-specific extension
110 operations to determine which devices and printer drivers are available
113 <P>Further information on the CUPS implementation of IPP can be found
119 <P>CUPS 1.2 includes many changes from the 1.1.x releases.
121 <H2>Directory Structure</H2>
123 <P>The directory structure in CUPS 1.2 has been modified to conform to the

188 <P>CUPS 1.2 is based on version 1.1 of the Internet Printing Protocol.
190 <P>The new scheduler supports the <CODE>create-job</CODE> and
191 <CODE>send-document</CODE> operations. In addition, the
192 <CODE>job-sheets</CODE>, <CODE>job-sheets-default</CODE>, and
193 <CODE>job-sheets-supported</CODE> attributes are now supported for
196 <P>The <CODE>CUPS-get-printers</CODE> and <CODE>CUPS-get-classes</CODE>
197 operations have been upgraded to support limited filtering based upon
198 the <CODE>printer-type</CODE>, <CODE>printer-location</CODE>,
199 <CODE>printer-info</CODE>, and <CODE>printer-make-and-model</CODE>
202 <P>The <CODE>CUPS-add-printer</CODE> operation now supports the
203 <CODE>ppd-name</CODE> attribute to specify a locally-available PPD file
204 rather than sending the PPD file from the client with the request.
