503<p>The CUPS PPD API provides read-only access the data in PostScript Printer
504Description ("PPD") files which are used for all printers with a driver. With
79e1d494
MS
505it you can obtain the data necessary to display printer options to users, mark
506option choices and check for conflicting choices, and output marked choices in
507PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
508structure contains all of the information in a PPD file.</p>
509
510<blockquote><b>Note:</b>
511
512<p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
513terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
514features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
515values as case-insensitive strings, so option "InputSlot" and choice "Upper"
516are equivalent to "inputslot" and "upper", respectively.</p>
517</blockquote>

5a738aea 519<h3><a name="LOADING">Loading a PPD File</a></h3>
ef416fc2 520
5a738aea
MS
521<p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
522PPD file and loads it into memory. For example, the following code opens the
523current printer's PPD file in a CUPS filter:</p>
ef416fc2 524
5a738aea
MS
525<pre class="example">
526#include &lt;cups/ppd.h&gt;
ef416fc2 527
5a738aea 528<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
ef416fc2 529</pre>
530
5a738aea
MS
531<p>The return value is a pointer to a new
532<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
533if the PPD file does not exist or cannot be loaded. The
534<a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
535by the structure:</p>
536
537<pre class="example">
538#include &lt;cups/ppd.h&gt;
539
540<a href="#ppd_file_t">ppd_file_t</a> *ppd;
541
542<a href="#ppdClose">ppdClose</a>(ppd);
543</pre>
544
79e1d494
MS
545<p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
546structure and any data in it will no longer be valid.</p>
547
5a738aea
MS
548<h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
549
550<p>PPD files support multiple options, which are stored in arrays of
551<a href="#ppd_option_t"><code>ppd_option_t</code></a> and
552<a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
553
554<p>Each option in turn is associated with a group stored in a
555<a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
556specified in the PPD file; if an option is not associated with a group
557then it is put in an automatically-generated "General" group. Groups can also
558have sub-groups, however CUPS currently ignores sub-groups because of past
559abuses of this functionality.</p>
560
79e1d494 561<p>Option choices are selected by marking them using one of three functions. The
5a738aea
MS
562first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
563selects all of the default options in the PPD file:</p>
564
565<pre class="example">
566#include &lt;cups/ppd.h&gt;
567
568<a href="#ppd_file_t">ppd_file_t</a> *ppd;
569
570<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
571</pre>
572
573<p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
574which selects a single option choice in the PPD file. For example, the following
79e1d494 575code selects the upper paper tray:</p>
5a738aea
MS
576
577<pre class="example">
578#include &lt;cups/ppd.h&gt;
579
580<a href="#ppd_file_t">ppd_file_t</a> *ppd;
581
79e1d494 582<a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
5a738aea
MS
583</pre>
584
585<p>The last function is
586<a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
587multiple option choices in the PPD file from an array of CUPS options, mapping
588IPP attributes like "media" and "sides" to their corresponding PPD options. You
589typically use this function in a print filter with
590<code>cupsParseOptions</code> and
591<a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
592the option choices needed for the job, for example:</p>
593
594<pre class="example">
595#include &lt;cups/ppd.h&gt;
596
597<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
598cups_option_t *options = NULL;
599int num_options = cupsParseOptions(argv[5], 0, &amp;options);
600
601<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
602<a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
79e1d494 603cupsFreeOptions(num_options, options);
5a738aea
MS
604</pre>
605
606<h3><a name="CONSTRAINTS">Constraints</a></h3>
607
608<p>PPD files support specification of conflict conditions, called
609constraints, between different options. Constraints are stored in an array of
610<a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
611the options and choices that conflict with each other. The
612<a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
79e1d494
MS
613how many of the selected options are incompatible. Since constraints are
614normally specified in pairs, the returned value is typically an even number.</p>
5a738aea
MS
615
616<h3><a name="PAGE_SIZES">Page Sizes</a></h3>
617
618<p>Page sizes are special options which have physical dimensions and margins
619associated with them. The size information is stored in
620<a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
621by looking up the named size with the
622<a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
623margins are returned in units called points; there are 72 points per inch. If
624you pass <code>NULL</code> for the size, the currently selected size is
625returned:</p>
626
627<pre class="example">
628#include &lt;cups/ppd.h&gt;
629
630<a href="#ppd_file_t">ppd_file_t</a> *ppd;
631<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
632</pre>
633
634<p>Besides the standard page sizes listed in a PPD file, some printers
635support variable or custom page sizes. Custom page sizes are supported if the
636<code>variables_sizes</code> member of the
637<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
638The <code>custom_min</code>, <code>custom_max</code>, and
639<code>custom_margins</code> members of the
640<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
641of the printable area. To get the resulting media size, use a page size string
642of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
643in points. Custom page size names can also be specified in inches
644("Custom.<i>width</i>x<i>height</i>in"), centimeters
645("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
646("Custom.<i>width</i>x<i>height</i>mm"):</p>
647
648<pre class="example">
649#include &lt;cups/ppd.h&gt;
650
651<a href="#ppd_file_t">ppd_file_t</a> *ppd;
652
653/* Get an 576x720 point custom page size */
654<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
655
656/* Get an 8x10 inch custom page size */
657<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
658
659/* Get a 100x200 millimeter custom page size */
660<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
661
662/* Get a 12.7x34.5 centimeter custom page size */
663<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
664</pre>
665
79e1d494
MS
666<p>If the PPD does not support variable page sizes, the
667<a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
668<code>NULL</code>.</p>
669
5a738aea
MS
670<h3><a name="ATTRIBUTES">Attributes</a></h3>
671
672<p>Every PPD file is composed of one or more attributes. Most of these
673attributes are used to define groups, options, choices, and page sizes,
79e1d494
MS
674however several informational attributes may be present which you can access
675in your program or filter. Attributes normally look like one of the following
676examples in a PPD file:</p>
5a738aea
MS
677
678<pre class="example">
679*name: "value"
680*name spec: "value"
681*name spec/text: "value"
682</pre>
683
684<p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
685<a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
686first and next instances, respectively, of the named attribute with the given
687"spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
688structure. If you provide a NULL specifier string, all attributes with the
689given name will be returned. For example, the following code lists all of the
690<code>Product</code> attributes in a PPD file:</p>
691
692<pre class="example">
693#include &lt;cups/ppd.h&gt;
694
695<a href="#ppd_file_t">ppd_file_t</a> *ppd;
696<a href="#ppd_attr_t">ppd_attr_t</a> *attr;
697
698for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
699 attr != NULL;
700 attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
701 puts(attr->value);

788a list of option changes that are required to resolve them. On input,

790not yet been marked, while &quot;option&quot; and &quot;choice&quot; contain the most recent
66ab9486
MS
791selection which may or may not be in &quot;num_options&quot; or &quot;options&quot;.<br>
792<br>
793On successful return, &quot;num_options&quot; and &quot;options&quot; are updated to contain

797If option conflicts cannot be resolved, &quot;num_options&quot; and &quot;options&quot; are not

799<br>
800When resolving conflicts, <code>cupsResolveConflicts</code> does not consider
801changes to the current page size (<code>media</code>, <code>PageSize</code>, and
802<code>PageRegion</code>) or to the most recent option specified in &quot;option&quot;.
803Thus, if the only way to resolve a conflict is to change the page size

805will return 0 to indicate it was unable to resolve the conflicts.<br>
806<br>
807The <code>cupsResolveConflicts</code> function uses one of two sources of option
808constraint information. The preferred constraint information is defined by
66ab9486 809<code>cupsUIConstraints</code> and <code>cupsUIResolver</code> attributes - in this
06d4e77b 810case, the PPD file provides constraint resolution actions.<br>
66ab9486 811<br>
06d4e77b 812The backup constraint information is defined by the

06d4e77b
MS
814constraints are resolved algorithmically by first selecting the default
815choice for the conflicting option, then iterating over all possible choices
