478 PPD API introduction for the Common UNIX Printing System (CUPS).

490 <h2 class='title'
><a name='OVERVIEW'
>Overview
</a></h2>
492 <p>The CUPS PPD API provides read-only access the data in PostScript Printer
493 Description (
"PPD") files which are used for all printers with a driver. With
494 it you can obtain the data necessary to display printer options to users, mark
495 option choices and check for conflicting choices, and output marked choices in
496 PostScript output. The
<a href=
"#ppd_file_t"><code>ppd_file_t
</code></a>
497 structure contains all of the information in a PPD file.
</p>
499 <blockquote><b>Note:
</b>
501 <p>The CUPS PPD API uses the terms
"option" and
"choice" instead of the Adobe
502 terms
"MainKeyword" and
"OptionKeyword" to refer to specific printer options and
503 features. CUPS also treats option (
"MainKeyword") and choice (
"OptionKeyword")
504 values as case-insensitive strings, so option
"InputSlot" and choice
"Upper"
505 are equivalent to
"inputslot" and
"upper", respectively.
</p>
508 <h3><a name=
"LOADING">Loading a PPD File
</a></h3>
510 <p>The
<a href=
"#ppdOpenFile"><code>ppdOpenFile
</code></a> function
"opens" a
511 PPD file and loads it into memory. For example, the following code opens the
512 current printer's PPD file in a CUPS filter:
</p>
514 <pre class=
"example">
515 #include
<cups/ppd.h
>
517 <a href=
"#ppd_file_t">ppd_file_t
</a> *ppd =
<a href=
"#ppdOpenFile">ppdOpenFile
</a>(getenv(
"PPD"));
520 <p>The return value is a pointer to a new
521 <a href=
"#ppd_file_t"><code>ppd_file_t
</code></a> structure or
<code>NULL
</code>
522 if the PPD file does not exist or cannot be loaded. The
523 <a href=
"#ppdClose"><code>ppdClose
</code></a> function frees the memory used
524 by the structure:
</p>
526 <pre class=
"example">
527 #include
<cups/ppd.h
>
529 <a href=
"#ppd_file_t">ppd_file_t
</a> *ppd;
531 <a href=
"#ppdClose">ppdClose
</a>(ppd);
534 <p>Once closed, pointers to the
<a href=
"#ppd_file_t"><code>ppd_file_t
</code></a>
535 structure and any data in it will no longer be valid.
</p>
537 <h3><a name=
"OPTIONS_AND_GROUPS">Options and Groups
</a></h3>
539 <p>PPD files support multiple options, which are stored in arrays of
540 <a href=
"#ppd_option_t"><code>ppd_option_t
</code></a> and
541 <a href=
"#ppd_choice_t"><code>ppd_choice_t
</code></a> structures.
</p>
543 <p>Each option in turn is associated with a group stored in a
544 <a href=
"#ppd_group_t"><code>ppd_group_t
</code></a> structure. Groups can be
545 specified in the PPD file; if an option is not associated with a group
546 then it is put in an automatically-generated
"General" group. Groups can also
547 have sub-groups, however CUPS currently ignores sub-groups because of past
548 abuses of this functionality.
</p>
550 <p>Option choices are selected by marking them using one of three functions. The
551 first is
<a href=
"#ppdMarkDefaults"><code>ppdMarkDefaults
</code></a> which
552 selects all of the default options in the PPD file:
</p>
554 <pre class=
"example">
555 #include
<cups/ppd.h
>
557 <a href=
"#ppd_file_t">ppd_file_t
</a> *ppd;
559 <a href=
"#ppdMarkDefaults">ppdMarkDefaults
</a>(ppd);
562 <p>The second is
<a href=
"#ppdMarkOption"><code>ppdMarkOption
</code></a>
563 which selects a single option choice in the PPD file. For example, the following
564 code selects the upper paper tray:
</p>
566 <pre class=
"example">
567 #include
<cups/ppd.h
>
569 <a href=
"#ppd_file_t">ppd_file_t
</a> *ppd;
571 <a href=
"#ppdMarkOption">ppdMarkOption
</a>(ppd,
"InputSlot",
"Upper");
574 <p>The last function is
575 <a href=
"#cupsMarkOptions"><code>cupsMarkOptions
</code></a> which selects
576 multiple option choices in the PPD file from an array of CUPS options, mapping
577 IPP attributes like
"media" and
"sides" to their corresponding PPD options. You
578 typically use this function in a print filter with
579 <code>cupsParseOptions
</code> and
580 <a href=
"#ppdMarkDefaults"><code>ppdMarkDefaults
</code></a> to select all of
581 the option choices needed for the job, for example:
</p>
583 <pre class=
"example">
584 #include
<cups/ppd.h
>
586 <a href=
"#ppd_file_t">ppd_file_t
</a> *ppd =
<a href=
"#ppdOpenFile">ppdOpenFile
</a>(getenv(
"PPD"));
587 cups_option_t *options = NULL;
588 int num_options = cupsParseOptions(argv[
5],
0,
&options);
590 <a href=
"#ppdMarkDefaults">ppdMarkDefaults
</a>(ppd);
591 <a href=
"#cupsMarkOptions">cupsMarkOptions
</a>(ppd, num_options, options);
592 cupsFreeOptions(num_options, options);
595 <h3><a name=
"CONSTRAINTS">Constraints
</a></h3>
597 <p>PPD files support specification of conflict conditions, called
598 constraints, between different options. Constraints are stored in an array of
599 <a href=
"#ppd_const_t"><code>ppd_const_t
</code></a> structures which specify
600 the options and choices that conflict with each other. The
601 <a href=
"#ppdConflicts"><code>ppdConflicts
</code></a> function tells you
602 how many of the selected options are incompatible. Since constraints are
603 normally specified in pairs, the returned value is typically an even number.
</p>
605 <h3><a name=
"PAGE_SIZES">Page Sizes
</a></h3>
607 <p>Page sizes are special options which have physical dimensions and margins
608 associated with them. The size information is stored in
609 <a href=
"#ppd_size_t"><code>ppd_size_t
</code></a> structures and is available
610 by looking up the named size with the
611 <a href=
"#ppdPageSize"><code>ppdPageSize
</code></a> function. The page size and
612 margins are returned in units called points; there are
72 points per inch. If
613 you pass
<code>NULL
</code> for the size, the currently selected size is
616 <pre class=
"example">
617 #include
<cups/ppd.h
>
619 <a href=
"#ppd_file_t">ppd_file_t
</a> *ppd;
620 <a href=
"#ppd_size_t">ppd_size_t
</a> *size =
<a href=
"#ppdPageSize">ppdPageSize
</a>(ppd, NULL);
623 <p>Besides the standard page sizes listed in a PPD file, some printers
624 support variable or custom page sizes. Custom page sizes are supported if the
625 <code>variables_sizes
</code> member of the

659 <h3><a name=
"ATTRIBUTES">Attributes
</a></h3>
661 <p>Every PPD file is composed of one or more attributes. Most of these
662 attributes are used to define groups, options, choices, and page sizes,
663 however several informational attributes may be present which you can access
664 in your program or filter. Attributes normally look like one of the following
665 examples in a PPD file:
</p>
667 <pre class=
"example">
670 *name spec/text:
"value"
673 <p>The
<a href=
"#ppdFindAttr"><code>ppdFindAttr
</code></a> and
674 <a href=
"#ppdFindNextAttr"><code>ppdFindNextAttr
</code></a> functions find the
675 first and next instances, respectively, of the named attribute with the given
676 "spec" string and return a
<a href=
"#ppd_attr_t"><code>ppd_attr_t
</code></a>
677 structure. If you provide a NULL specifier string, all attributes with the
678 given name will be returned. For example, the following code lists all of the
679 <code>Product
</code> attributes in a PPD file:

775 <p class=
"discussion">This function attempts to resolve any conflicts in a marked PPD, returning
776 a list of option changes that are required to resolve them. On input,
777 "num_options
" and
"options
" contain any pending option changes that have
778 not yet been marked, while
"option
" and
"choice
" contain the most recent
779 selection which may or may not be in
"num_options
" or
"options
".
<br>
781 On successful return,
"num_options
" and
"options
" are updated to contain
782 "option
" and
"choice
" along with any changes required to resolve conflicts
783 specified in the PPD file and
1 is returned.
<br>
785 If option conflicts cannot be resolved,
"num_options
" and
"options
" are not
786 changed and
0 is returned.
<br>
788 When resolving conflicts,
<code>cupsResolveConflicts
</code> does not consider
789 changes to the current page size (
<code>media
</code>,
<code>PageSize
</code>, and
790 <code>PageRegion
</code>) or to the most recent option specified in
"option
".
791 Thus, if the only way to resolve a conflict is to change the page size
792 or the option the user most recently changed,
<code>cupsResolveConflicts
</code>
793 will return
0 to indicate it was unable to resolve the conflicts.
<br>
795 The
<code>cupsResolveConflicts
</code> function uses one of two sources of option
796 constraint information. The preferred constraint information is defined by
797 <code>cupsUIConstraints
</code> and
<code>cupsUIResolver
</code> attributes - in this
798 case, the PPD file provides constraint resolution actions.
<br>
800 The backup constraint information is defined by the
801 <code>UIConstraints
</code> and
<code>NonUIConstraints
</code> attributes. These
802 constraints are resolved algorithmically by first selecting the default
803 choice for the conflicting option, then iterating over all possible choices
804 until a non-conflicting option choice is found.
