409<p>The CUPS PPD API provides read-only access the data in PostScript Printer
410Description ("PPD") files which are used for all printers with a driver. With
411it you can display printer options to users, mark option choices and check for
412conflicting choices, and output marked choices in PostScript output. The
413<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure contains all of
414the information in a PPD file.</p>
ef416fc2 415
5a738aea 416<h3><a name="LOADING">Loading a PPD File</a></h3>
ef416fc2 417
5a738aea
MS
418<p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
419PPD file and loads it into memory. For example, the following code opens the
420current printer's PPD file in a CUPS filter:</p>
ef416fc2 421
5a738aea
MS
422<pre class="example">
423#include &lt;cups/ppd.h&gt;
ef416fc2 424
5a738aea 425<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
ef416fc2 426</pre>
427
5a738aea
MS
428<p>The return value is a pointer to a new
429<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
430if the PPD file does not exist or cannot be loaded. The
431<a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
432by the structure:</p>
433
434<pre class="example">
435#include &lt;cups/ppd.h&gt;
436
437<a href="#ppd_file_t">ppd_file_t</a> *ppd;
438
439<a href="#ppdClose">ppdClose</a>(ppd);
440</pre>
441
442<h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
443
444<p>PPD files support multiple options, which are stored in arrays of
445<a href="#ppd_option_t"><code>ppd_option_t</code></a> and
446<a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
447
448<p>Each option in turn is associated with a group stored in a
449<a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
450specified in the PPD file; if an option is not associated with a group
451then it is put in an automatically-generated "General" group. Groups can also
452have sub-groups, however CUPS currently ignores sub-groups because of past
453abuses of this functionality.</p>
454
455<p>Options are selected by marking them using one of three functions. The
456first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
457selects all of the default options in the PPD file:</p>
458
459<pre class="example">
460#include &lt;cups/ppd.h&gt;
461
462<a href="#ppd_file_t">ppd_file_t</a> *ppd;
463
464<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
465</pre>
466
467<p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
468which selects a single option choice in the PPD file. For example, the following
469code selects the manual feed media source:</p>
470
471<pre class="example">
472#include &lt;cups/ppd.h&gt;
473

479<p>The last function is
480<a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
481multiple option choices in the PPD file from an array of CUPS options, mapping
482IPP attributes like "media" and "sides" to their corresponding PPD options. You
483typically use this function in a print filter with
484<code>cupsParseOptions</code> and
485<a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
486the option choices needed for the job, for example:</p>
487
488<pre class="example">
489#include &lt;cups/ppd.h&gt;
490
491<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
492cups_option_t *options = NULL;
493int num_options = cupsParseOptions(argv[5], 0, &amp;options);
494
495<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
496<a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
497</pre>
498
499<h3><a name="CONSTRAINTS">Constraints</a></h3>
500
501<p>PPD files support specification of conflict conditions, called
502constraints, between different options. Constraints are stored in an array of
503<a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
504the options and choices that conflict with each other. The
505<a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
506how many of the selected options are incompatible.</p>
507
508<h3><a name="PAGE_SIZES">Page Sizes</a></h3>
509
510<p>Page sizes are special options which have physical dimensions and margins
511associated with them. The size information is stored in
512<a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
513by looking up the named size with the
514<a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
515margins are returned in units called points; there are 72 points per inch. If
516you pass <code>NULL</code> for the size, the currently selected size is
517returned:</p>
518
519<pre class="example">
520#include &lt;cups/ppd.h&gt;
521
522<a href="#ppd_file_t">ppd_file_t</a> *ppd;
523<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
524</pre>
525
526<p>Besides the standard page sizes listed in a PPD file, some printers
527support variable or custom page sizes. Custom page sizes are supported if the
528<code>variables_sizes</code> member of the
529<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
530The <code>custom_min</code>, <code>custom_max</code>, and
531<code>custom_margins</code> members of the
532<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
533of the printable area. To get the resulting media size, use a page size string
534of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
535in points. Custom page size names can also be specified in inches
536("Custom.<i>width</i>x<i>height</i>in"), centimeters
537("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
538("Custom.<i>width</i>x<i>height</i>mm"):</p>
539
540<pre class="example">
541#include &lt;cups/ppd.h&gt;
542
543<a href="#ppd_file_t">ppd_file_t</a> *ppd;

546<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
547

549<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");

552<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
553
554/* Get a 12.7x34.5 centimeter custom page size */
555<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
556</pre>
557
558<h3><a name="ATTRIBUTES">Attributes</a></h3>
559
560<p>Every PPD file is composed of one or more attributes. Most of these
561attributes are used to define groups, options, choices, and page sizes,
562however several informations attributes are available which you may need
563to access in your program or filter. Attributes normally look like one of
564the following examples in a PPD file:</p>
565
566<pre class="example">
567*name: "value"
568*name spec: "value"
569*name spec/text: "value"
570</pre>
571
572<p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
573<a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
574first and next instances, respectively, of the named attribute with the given
575"spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
576structure. If you provide a NULL specifier string, all attributes with the
577given name will be returned. For example, the following code lists all of the
578<code>Product</code> attributes in a PPD file:</p>
579
580<pre class="example">
581#include &lt;cups/ppd.h&gt;
582
583<a href="#ppd_file_t">ppd_file_t</a> *ppd;
584<a href="#ppd_attr_t">ppd_attr_t</a> *attr;
585
586for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
587 attr != NULL;
588 attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
589 puts(attr->value);
