 503 <h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
 504
 505 <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>
 506
 507 <p>The CUPS PPD API provides read-only access the data in PostScript Printer
 508 Description ("PPD") files which are used for all printers with a driver. With
 509 it you can obtain the data necessary to display printer options to users, mark
 510 option choices and check for conflicting choices, and output marked choices in
 511 PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 512 structure contains all of the information in a PPD file.</p>
 513
 514 <blockquote><b>Note:</b>
 515
 516 <p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
 517 terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
 518 features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
 519 values as case-insensitive strings, so option "InputSlot" and choice "Upper"
 520 are equivalent to "inputslot" and "upper", respectively.</p>
 521 </blockquote>
 522
 523 <h3><a name="LOADING">Loading a PPD File</a></h3>
 524
 525 <p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
 526 PPD file and loads it into memory. For example, the following code opens the
 527 current printer's PPD file in a CUPS filter:</p>
 528
 529 <pre class="example">
 530 #include &lt;cups/ppd.h&gt;
 531
 532 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 533 </pre>
 534
 535 <p>The return value is a pointer to a new
 536 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
 537 if the PPD file does not exist or cannot be loaded. The
 538 <a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
 539 by the structure:</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;
 545
 546 <a href="#ppdClose">ppdClose</a>(ppd);
 547 </pre>
 548
 549 <p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 550 structure and any data in it will no longer be valid.</p>
 551
 552 <h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
 553
 554 <p>PPD files support multiple options, which are stored in arrays of
 555 <a href="#ppd_option_t"><code>ppd_option_t</code></a> and
 556 <a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
 557
 558 <p>Each option in turn is associated with a group stored in a
 559 <a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
 560 specified in the PPD file; if an option is not associated with a group
 561 then it is put in an automatically-generated "General" group. Groups can also
 562 have sub-groups, however CUPS currently ignores sub-groups because of past
 563 abuses of this functionality.</p>
 564
 565 <p>Option choices are selected by marking them using one of three functions. The
 566 first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
 567 selects all of the default options in the PPD file:</p>
 568
 569 <pre class="example">
 570 #include &lt;cups/ppd.h&gt;
 571
 572 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 573
 574 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 575 </pre>
 576
 577 <p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
 578 which selects a single option choice in the PPD file. For example, the following
 579 code selects the upper paper tray:</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="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
 587 </pre>
 588
 589 <p>The last function is
 590 <a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
 591 multiple option choices in the PPD file from an array of CUPS options, mapping
 592 IPP attributes like "media" and "sides" to their corresponding PPD options. You
 593 typically use this function in a print filter with
 594 <code>cupsParseOptions</code> and
 595 <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
 596 the option choices needed for the job, for example:</p>
 597
 598 <pre class="example">
 599 #include &lt;cups/ppd.h&gt;
 600
 601 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 602 cups_option_t *options = NULL;
 603 int num_options = cupsParseOptions(argv[5], 0, &amp;options);
 604
 605 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 606 <a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
 607 cupsFreeOptions(num_options, options);
 608 </pre>
 609
 610 <h3><a name="CONSTRAINTS">Constraints</a></h3>
 611
 612 <p>PPD files support specification of conflict conditions, called
 613 constraints, between different options. Constraints are stored in an array of
 614 <a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
 615 the options and choices that conflict with each other. The
 616 <a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
 617 how many of the selected options are incompatible. Since constraints are
 618 normally specified in pairs, the returned value is typically an even number.</p>
 619
 620 <h3><a name="PAGE_SIZES">Page Sizes</a></h3>
 621
 622 <p>Page sizes are special options which have physical dimensions and margins
 623 associated with them. The size information is stored in
 624 <a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
 625 by looking up the named size with the
 626 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
 627 margins are returned in units called points; there are 72 points per inch. If
 628 you pass <code>NULL</code> for the size, the currently selected size is
 629 returned:</p>
 630
 631 <pre class="example">
 632 #include &lt;cups/ppd.h&gt;
 633
 634 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 635 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
 636 </pre>
 637
 638 <p>Besides the standard page sizes listed in a PPD file, some printers
 639 support variable or custom page sizes. Custom page sizes are supported if the
 640 <code>variables_sizes</code> member of the
 641 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
 642 The <code>custom_min</code>, <code>custom_max</code>, and
 643 <code>custom_margins</code> members of the
 644 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
 645 of the printable area. To get the resulting media size, use a page size string
 646 of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
 647 in points. Custom page size names can also be specified in inches
 648 ("Custom.<i>width</i>x<i>height</i>in"), centimeters
 649 ("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
 650 ("Custom.<i>width</i>x<i>height</i>mm"):</p>
 651
 652 <pre class="example">
 653 #include &lt;cups/ppd.h&gt;
 654
 655 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 656
 657 /* Get an 576x720 point custom page size */
 658 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
 659
 660 /* Get an 8x10 inch custom page size */
 661 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
 662
 663 /* Get a 100x200 millimeter custom page size */
 664 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
 665
 666 /* Get a 12.7x34.5 centimeter custom page size */
 667 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
 668 </pre>
 669
 670 <p>If the PPD does not support variable page sizes, the
 671 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
 672 <code>NULL</code>.</p>
 673
 674 <h3><a name="ATTRIBUTES">Attributes</a></h3>
 675
 676 <p>Every PPD file is composed of one or more attributes. Most of these
 677 attributes are used to define groups, options, choices, and page sizes,
 678 however several informational attributes may be present which you can access
 679 in your program or filter. Attributes normally look like one of the following
 680 examples in a PPD file:</p>
 681
 682 <pre class="example">
 683 *name: "value"
 684 *name spec: "value"
 685 *name spec/text: "value"
 686 </pre>
 687
 688 <p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
 689 <a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
 690 first and next instances, respectively, of the named attribute with the given
 691 "spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
 692 structure. If you provide a NULL specifier string, all attributes with the
 693 given name will be returned. For example, the following code lists all of the
 694 <code>Product</code> attributes in a PPD file:</p>
 695
 696 <pre class="example">
 697 #include &lt;cups/ppd.h&gt;
 698
 699 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 700 <a href="#ppd_attr_t">ppd_attr_t</a> *attr;
 701
 702 for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
 703      attr != NULL;
 704      attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
 705   puts(attr->value);
 706 </pre>

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