409<h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
410
411<p>The CUPS PPD API provides read-only access the data in PostScript Printer
412Description ("PPD") files which are used for all printers with a driver. With
413it you can obtain the data necessary to display printer options to users, mark
414option choices and check for conflicting choices, and output marked choices in
415PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
416structure contains all of the information in a PPD file.</p>
417
418<blockquote><b>Note:</b>
419
420<p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
421terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
422features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
423values as case-insensitive strings, so option "InputSlot" and choice "Upper"
424are equivalent to "inputslot" and "upper", respectively.</p>
425</blockquote>
426
427<h3><a name="LOADING">Loading a PPD File</a></h3>
428
429<p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
430PPD file and loads it into memory. For example, the following code opens the
431current printer's PPD file in a CUPS filter:</p>
432
433<pre class="example">
434#include &lt;cups/ppd.h&gt;
435
436<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
437</pre>
438
439<p>The return value is a pointer to a new
440<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
441if the PPD file does not exist or cannot be loaded. The
442<a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
443by the structure:</p>
444
445<pre class="example">
446#include &lt;cups/ppd.h&gt;
447
448<a href="#ppd_file_t">ppd_file_t</a> *ppd;
449
450<a href="#ppdClose">ppdClose</a>(ppd);
451</pre>
452
453<p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
454structure and any data in it will no longer be valid.</p>
455
456<h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
457
458<p>PPD files support multiple options, which are stored in arrays of
459<a href="#ppd_option_t"><code>ppd_option_t</code></a> and
460<a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
461
462<p>Each option in turn is associated with a group stored in a
463<a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
464specified in the PPD file; if an option is not associated with a group
465then it is put in an automatically-generated "General" group. Groups can also
466have sub-groups, however CUPS currently ignores sub-groups because of past
467abuses of this functionality.</p>
468
469<p>Option choices are selected by marking them using one of three functions. The
470first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
471selects all of the default options in the PPD file:</p>
472
473<pre class="example">
474#include &lt;cups/ppd.h&gt;

477
478<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
479</pre>
480
481<p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
482which selects a single option choice in the PPD file. For example, the following
483code selects the upper paper tray:</p>
484
485<pre class="example">
486#include &lt;cups/ppd.h&gt;
487
488<a href="#ppd_file_t">ppd_file_t</a> *ppd;
489
490<a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
491</pre>
492
493<p>The last function is
494<a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
495multiple option choices in the PPD file from an array of CUPS options, mapping
496IPP attributes like "media" and "sides" to their corresponding PPD options. You
497typically use this function in a print filter with
498<code>cupsParseOptions</code> and
499<a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
500the option choices needed for the job, for example:</p>
501
502<pre class="example">
503#include &lt;cups/ppd.h&gt;
504
505<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
506cups_option_t *options = NULL;
507int num_options = cupsParseOptions(argv[5], 0, &amp;options);
508
509<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
510<a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
511cupsFreeOptions(num_options, options);
512</pre>
513
514<h3><a name="CONSTRAINTS">Constraints</a></h3>
515
516<p>PPD files support specification of conflict conditions, called
517constraints, between different options. Constraints are stored in an array of
518<a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
519the options and choices that conflict with each other. The
520<a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
521how many of the selected options are incompatible. Since constraints are
522normally specified in pairs, the returned value is typically an even number.</p>
523
524<h3><a name="PAGE_SIZES">Page Sizes</a></h3>
525
526<p>Page sizes are special options which have physical dimensions and margins
527associated with them. The size information is stored in
528<a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
529by looking up the named size with the
530<a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
531margins are returned in units called points; there are 72 points per inch. If
532you pass <code>NULL</code> for the size, the currently selected size is
533returned:</p>
534
535<pre class="example">
536#include &lt;cups/ppd.h&gt;
537
538<a href="#ppd_file_t">ppd_file_t</a> *ppd;
539<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
540</pre>
541
542<p>Besides the standard page sizes listed in a PPD file, some printers
543support variable or custom page sizes. Custom page sizes are supported if the
544<code>variables_sizes</code> member of the
545<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
546The <code>custom_min</code>, <code>custom_max</code>, and
547<code>custom_margins</code> members of the
548<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
549of the printable area. To get the resulting media size, use a page size string
550of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
551in points. Custom page size names can also be specified in inches
552("Custom.<i>width</i>x<i>height</i>in"), centimeters
553("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
554("Custom.<i>width</i>x<i>height</i>mm"):</p>
555
556<pre class="example">
557#include &lt;cups/ppd.h&gt;
558
559<a href="#ppd_file_t">ppd_file_t</a> *ppd;
560
561/* Get an 576x720 point custom page size */
562<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
563
564/* Get an 8x10 inch custom page size */
565<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
566
567/* Get a 100x200 millimeter custom page size */
568<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
569
570/* Get a 12.7x34.5 centimeter custom page size */
571<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
572</pre>
573
574<p>If the PPD does not support variable page sizes, the
575<a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
576<code>NULL</code>.</p>
577
578<h3><a name="ATTRIBUTES">Attributes</a></h3>
579
580<p>Every PPD file is composed of one or more attributes. Most of these
581attributes are used to define groups, options, choices, and page sizes,
582however several informational attributes may be present which you can access
583in your program or filter. Attributes normally look like one of the following
584examples in a PPD file:</p>
585
586<pre class="example">
587*name: "value"
588*name spec: "value"
589*name spec/text: "value"
590</pre>
591
592<p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
593<a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
594first and next instances, respectively, of the named attribute with the given
595"spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
596structure. If you provide a NULL specifier string, all attributes with the
597given name will be returned. For example, the following code lists all of the
598<code>Product</code> attributes in a PPD file:</p>
599
600<pre class="example">
601#include &lt;cups/ppd.h&gt;
602
603<a href="#ppd_file_t">ppd_file_t</a> *ppd;
604<a href="#ppd_attr_t">ppd_attr_t</a> *attr;
605
606for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
607 attr != NULL;
608 attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
609 puts(attr->value);
