516
517<blockquote>The PPD API is deprecated starting in CUPS 1.6/OS X 10.8. Please use the new Job Ticket APIs in the <a href="api-cups.html">CUPS API</a> documentation. These functions will be removed in a future release of CUPS.</blockquote>
518
519<p>The CUPS PPD API provides read-only access the data in PostScript Printer
520Description ("PPD") files which are used for all printers with a driver. With
521it you can obtain the data necessary to display printer options to users, mark
522option choices and check for conflicting choices, and output marked choices in
523PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
524structure contains all of the information in a PPD file.</p>
525
526<blockquote><b>Note:</b>
527
528<p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
529terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
530features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
531values as case-insensitive strings, so option "InputSlot" and choice "Upper"
532are equivalent to "inputslot" and "upper", respectively.</p>
533</blockquote>
534
535<h3><a name="LOADING">Loading a PPD File</a></h3>
536
537<p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
538PPD file and loads it into memory. For example, the following code opens the
539current printer's PPD file in a CUPS filter:</p>
540
541<pre class="example">
542#include &lt;cups/ppd.h&gt;
543
544<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
545</pre>
546
547<p>The return value is a pointer to a new
548<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
549if the PPD file does not exist or cannot be loaded. The
550<a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
551by the structure:</p>
552
553<pre class="example">
554#include &lt;cups/ppd.h&gt;
555
556<a href="#ppd_file_t">ppd_file_t</a> *ppd;
557
558<a href="#ppdClose">ppdClose</a>(ppd);
559</pre>
560
561<p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
562structure and any data in it will no longer be valid.</p>
563
564<h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
565
566<p>PPD files support multiple options, which are stored in arrays of
567<a href="#ppd_option_t"><code>ppd_option_t</code></a> and
568<a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
569
570<p>Each option in turn is associated with a group stored in a
571<a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
572specified in the PPD file; if an option is not associated with a group
573then it is put in an automatically-generated "General" group. Groups can also
574have sub-groups, however CUPS currently ignores sub-groups because of past
575abuses of this functionality.</p>
576
577<p>Option choices are selected by marking them using one of three functions. The
578first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
579selects all of the default options in the PPD file:</p>
580
581<pre class="example">
582#include &lt;cups/ppd.h&gt;
583
584<a href="#ppd_file_t">ppd_file_t</a> *ppd;
585
586<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
587</pre>
588
589<p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
590which selects a single option choice in the PPD file. For example, the following
591code selects the upper paper tray:</p>
592
593<pre class="example">
594#include &lt;cups/ppd.h&gt;
595
596<a href="#ppd_file_t">ppd_file_t</a> *ppd;
597
598<a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
599</pre>
600
601<p>The last function is
602<a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
603multiple option choices in the PPD file from an array of CUPS options, mapping
604IPP attributes like "media" and "sides" to their corresponding PPD options. You
605typically use this function in a print filter with
606<code>cupsParseOptions</code> and
607<a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
608the option choices needed for the job, for example:</p>
609
610<pre class="example">
611#include &lt;cups/ppd.h&gt;
612
613<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
614cups_option_t *options = NULL;
615int num_options = cupsParseOptions(argv[5], 0, &amp;options);
616
617<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
618<a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
619cupsFreeOptions(num_options, options);
620</pre>
621
622<h3><a name="CONSTRAINTS">Constraints</a></h3>
623
624<p>PPD files support specification of conflict conditions, called
625constraints, between different options. Constraints are stored in an array of
626<a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
627the options and choices that conflict with each other. The
628<a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
629how many of the selected options are incompatible. Since constraints are
630normally specified in pairs, the returned value is typically an even number.</p>
631
632<h3><a name="PAGE_SIZES">Page Sizes</a></h3>
633
634<p>Page sizes are special options which have physical dimensions and margins
635associated with them. The size information is stored in
636<a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
637by looking up the named size with the
638<a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
639margins are returned in units called points; there are 72 points per inch. If
640you pass <code>NULL</code> for the size, the currently selected size is
641returned:</p>
642
643<pre class="example">
644#include &lt;cups/ppd.h&gt;
645
646<a href="#ppd_file_t">ppd_file_t</a> *ppd;
647<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
648</pre>
649
650<p>Besides the standard page sizes listed in a PPD file, some printers
651support variable or custom page sizes. Custom page sizes are supported if the
652<code>variables_sizes</code> member of the
653<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
654The <code>custom_min</code>, <code>custom_max</code>, and
655<code>custom_margins</code> members of the
656<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
657of the printable area. To get the resulting media size, use a page size string
658of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
659in points. Custom page size names can also be specified in inches
660("Custom.<i>width</i>x<i>height</i>in"), centimeters
661("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
662("Custom.<i>width</i>x<i>height</i>mm"):</p>
663
664<pre class="example">
665#include &lt;cups/ppd.h&gt;
666
667<a href="#ppd_file_t">ppd_file_t</a> *ppd;
668
669/* Get an 576x720 point custom page size */
670<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
671
672/* Get an 8x10 inch custom page size */
673<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
674
675/* Get a 100x200 millimeter custom page size */
676<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
677
678/* Get a 12.7x34.5 centimeter custom page size */
679<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
680</pre>
681
682<p>If the PPD does not support variable page sizes, the
683<a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
684<code>NULL</code>.</p>
685
686<h3><a name="ATTRIBUTES">Attributes</a></h3>
687
688<p>Every PPD file is composed of one or more attributes. Most of these
689attributes are used to define groups, options, choices, and page sizes,
690however several informational attributes may be present which you can access
691in your program or filter. Attributes normally look like one of the following
692examples in a PPD file:</p>
693
694<pre class="example">
695*name: "value"
696*name spec: "value"
697*name spec/text: "value"
698</pre>
699
700<p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
701<a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
702first and next instances, respectively, of the named attribute with the given
703"spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
704structure. If you provide a NULL specifier string, all attributes with the
705given name will be returned. For example, the following code lists all of the
706<code>Product</code> attributes in a PPD file:</p>
707
708<pre class="example">
709#include &lt;cups/ppd.h&gt;
710
711<a href="#ppd_file_t">ppd_file_t</a> *ppd;
712<a href="#ppd_attr_t">ppd_attr_t</a> *attr;
713
714for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
715     attr != NULL;
716     attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
717  puts(attr->value);
718</pre>

802<h4 class="discussion">Discussion</h4>
803<p class="discussion">This function attempts to resolve any conflicts in a marked PPD, returning
804a list of option changes that are required to resolve them.  On input,
805&quot;num_options&quot; and &quot;options&quot; contain any pending option changes that have
806not yet been marked, while &quot;option&quot; and &quot;choice&quot; contain the most recent
807selection which may or may not be in &quot;num_options&quot; or &quot;options&quot;.<br>
808<br>
809On successful return, &quot;num_options&quot; and &quot;options&quot; are updated to contain
810&quot;option&quot; and &quot;choice&quot; along with any changes required to resolve conflicts
811specified in the PPD file and 1 is returned.<br>
812<br>
813If option conflicts cannot be resolved, &quot;num_options&quot; and &quot;options&quot; are not
814changed and 0 is returned.<br>
815<br>
816When resolving conflicts, <code>cupsResolveConflicts</code> does not consider
817changes to the current page size (<code>media</code>, <code>PageSize</code>, and
818<code>PageRegion</code>) or to the most recent option specified in &quot;option&quot;.
819Thus, if the only way to resolve a conflict is to change the page size
820or the option the user most recently changed, <code>cupsResolveConflicts</code>
821will return 0 to indicate it was unable to resolve the conflicts.<br>
822<br>
823The <code>cupsResolveConflicts</code> function uses one of two sources of option
824constraint information.  The preferred constraint information is defined by
825<code>cupsUIConstraints</code> and <code>cupsUIResolver</code> attributes - in this
826case, the PPD file provides constraint resolution actions.<br>
827<br>
828The backup constraint information is defined by the
829<code>UIConstraints</code> and <code>NonUIConstraints</code> attributes.  These
830constraints are resolved algorithmically by first selecting the default
831choice for the conflicting option, then iterating over all possible choices
832until a non-conflicting option choice is found.
