 590 <h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
 591
 592 <blockquote>The PPD API is deprecated starting in CUPS 1.6/macOS 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>
 593
 594 <p>The CUPS PPD API provides read-only access the data in PostScript Printer
 595 Description ("PPD") files which are used for all printers with a driver. With
 596 it you can obtain the data necessary to display printer options to users, mark
 597 option choices and check for conflicting choices, and output marked choices in
 598 PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 599 structure contains all of the information in a PPD file.</p>
 600
 601 <blockquote><b>Note:</b>
 602
 603 <p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
 604 terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
 605 features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
 606 values as case-insensitive strings, so option "InputSlot" and choice "Upper"
 607 are equivalent to "inputslot" and "upper", respectively.</p>
 608 </blockquote>
 609
 610 <h3><a name="LOADING">Loading a PPD File</a></h3>
 611
 612 <p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
 613 PPD file and loads it into memory. For example, the following code opens the
 614 current printer's PPD file in a CUPS filter:</p>
 615
 616 <pre class="example">
 617 #include &lt;cups/ppd.h&gt;
 618
 619 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 620 </pre>
 621
 622 <p>The return value is a pointer to a new
 623 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
 624 if the PPD file does not exist or cannot be loaded. The
 625 <a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
 626 by the structure:</p>
 627
 628 <pre class="example">
 629 #include &lt;cups/ppd.h&gt;
 630
 631 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 632
 633 <a href="#ppdClose">ppdClose</a>(ppd);
 634 </pre>
 635
 636 <p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 637 structure and any data in it will no longer be valid.</p>
 638
 639 <h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
 640
 641 <p>PPD files support multiple options, which are stored in arrays of
 642 <a href="#ppd_option_t"><code>ppd_option_t</code></a> and
 643 <a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
 644
 645 <p>Each option in turn is associated with a group stored in a
 646 <a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
 647 specified in the PPD file; if an option is not associated with a group
 648 then it is put in an automatically-generated "General" group. Groups can also
 649 have sub-groups, however CUPS currently ignores sub-groups because of past
 650 abuses of this functionality.</p>
 651
 652 <p>Option choices are selected by marking them using one of three functions. The
 653 first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
 654 selects all of the default options in the PPD file:</p>
 655
 656 <pre class="example">
 657 #include &lt;cups/ppd.h&gt;
 658
 659 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 660
 661 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 662 </pre>
 663
 664 <p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
 665 which selects a single option choice in the PPD file. For example, the following
 666 code selects the upper paper tray:</p>
 667
 668 <pre class="example">
 669 #include &lt;cups/ppd.h&gt;
 670
 671 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 672
 673 <a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
 674 </pre>
 675
 676 <p>The last function is
 677 <a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
 678 multiple option choices in the PPD file from an array of CUPS options, mapping
 679 IPP attributes like "media" and "sides" to their corresponding PPD options. You
 680 typically use this function in a print filter with
 681 <code>cupsParseOptions</code> and
 682 <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
 683 the option choices needed for the job, for example:</p>
 684
 685 <pre class="example">
 686 #include &lt;cups/ppd.h&gt;
 687
 688 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 689 cups_option_t *options = NULL;
 690 int num_options = cupsParseOptions(argv[5], 0, &amp;options);
 691
 692 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 693 <a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
 694 cupsFreeOptions(num_options, options);
 695 </pre>
 696
 697 <h3><a name="CONSTRAINTS">Constraints</a></h3>
 698
 699 <p>PPD files support specification of conflict conditions, called
 700 constraints, between different options. Constraints are stored in an array of
 701 <a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
 702 the options and choices that conflict with each other. The
 703 <a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
 704 how many of the selected options are incompatible. Since constraints are
 705 normally specified in pairs, the returned value is typically an even number.</p>
 706
 707 <h3><a name="PAGE_SIZES">Page Sizes</a></h3>
 708
 709 <p>Page sizes are special options which have physical dimensions and margins
 710 associated with them. The size information is stored in
 711 <a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
 712 by looking up the named size with the
 713 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
 714 margins are returned in units called points; there are 72 points per inch. If
 715 you pass <code>NULL</code> for the size, the currently selected size is
 716 returned:</p>
 717
 718 <pre class="example">
 719 #include &lt;cups/ppd.h&gt;
 720
 721 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 722 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
 723 </pre>
 724
 725 <p>Besides the standard page sizes listed in a PPD file, some printers
 726 support variable or custom page sizes. Custom page sizes are supported if the
 727 <code>variables_sizes</code> member of the
 728 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
 729 The <code>custom_min</code>, <code>custom_max</code>, and
 730 <code>custom_margins</code> members of the
 731 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
 732 of the printable area. To get the resulting media size, use a page size string
 733 of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
 734 in points. Custom page size names can also be specified in inches
 735 ("Custom.<i>width</i>x<i>height</i>in"), centimeters
 736 ("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
 737 ("Custom.<i>width</i>x<i>height</i>mm"):</p>
 738
 739 <pre class="example">
 740 #include &lt;cups/ppd.h&gt;
 741
 742 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 743
 744 /* Get an 576x720 point custom page size */
 745 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
 746
 747 /* Get an 8x10 inch custom page size */
 748 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
 749
 750 /* Get a 100x200 millimeter custom page size */
 751 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
 752
 753 /* Get a 12.7x34.5 centimeter custom page size */
 754 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
 755 </pre>
 756
 757 <p>If the PPD does not support variable page sizes, the
 758 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
 759 <code>NULL</code>.</p>
 760
 761 <h3><a name="ATTRIBUTES">Attributes</a></h3>
 762
 763 <p>Every PPD file is composed of one or more attributes. Most of these
 764 attributes are used to define groups, options, choices, and page sizes,
 765 however several informational attributes may be present which you can access
 766 in your program or filter. Attributes normally look like one of the following
 767 examples in a PPD file:</p>
 768
 769 <pre class="example">
 770 *name: "value"
 771 *name spec: "value"
 772 *name spec/text: "value"
 773 </pre>
 774
 775 <p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
 776 <a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
 777 first and next instances, respectively, of the named attribute with the given
 778 "spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
 779 structure. If you provide a NULL specifier string, all attributes with the
 780 given name will be returned. For example, the following code lists all of the
 781 <code>Product</code> attributes in a PPD file:</p>
 782
 783 <pre class="example">
 784 #include &lt;cups/ppd.h&gt;
 785
 786 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 787 <a href="#ppd_attr_t">ppd_attr_t</a> *attr;
 788
 789 for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
 790      attr != NULL;
 791      attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
 792   puts(attr->value);
 793 </pre>

 965         <p class="discussion">This function attempts to resolve any conflicts in a marked PPD, returning
 966 a list of option changes that are required to resolve them.  On input,
 967 &quot;num_options&quot; and &quot;options&quot; contain any pending option changes that have
 968 not yet been marked, while &quot;option&quot; and &quot;choice&quot; contain the most recent
 969 selection which may or may not be in &quot;num_options&quot; or &quot;options&quot;.<br>
 970 <br>
 971 On successful return, &quot;num_options&quot; and &quot;options&quot; are updated to contain
 972 &quot;option&quot; and &quot;choice&quot; along with any changes required to resolve conflicts
 973 specified in the PPD file and 1 is returned.<br>
 974 <br>
 975 If option conflicts cannot be resolved, &quot;num_options&quot; and &quot;options&quot; are not
 976 changed and 0 is returned.<br>
 977 <br>
 978 When resolving conflicts, <code>cupsResolveConflicts</code> does not consider
 979 changes to the current page size (<code>media</code>, <code>PageSize</code>, and
 980 <code>PageRegion</code>) or to the most recent option specified in &quot;option&quot;.
 981 Thus, if the only way to resolve a conflict is to change the page size
 982 or the option the user most recently changed, <code>cupsResolveConflicts</code>
 983 will return 0 to indicate it was unable to resolve the conflicts.<br>
 984 <br>
 985 The <code>cupsResolveConflicts</code> function uses one of two sources of option
 986 constraint information.  The preferred constraint information is defined by
 987 <code>cupsUIConstraints</code> and <code>cupsUIResolver</code> attributes - in this
 988 case, the PPD file provides constraint resolution actions.<br>
 989 <br>
 990 The backup constraint information is defined by the
 991 <code>UIConstraints</code> and <code>NonUIConstraints</code> attributes.  These
 992 constraints are resolved algorithmically by first selecting the default
 993 choice for the conflicting option, then iterating over all possible choices
 994 until a non-conflicting option choice is found.
