<h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
<blockquote><b>Note:</b>
<p>The PPD API was deprecated in CUPS 1.6/macOS 10.8. Please use the new Job Ticket APIs in the <a href="cupspm.html">CUPS Programming Manual</a> documentation. These functions will be removed in a future release of CUPS.</p>
</blockquote>
<p>The CUPS PPD API provides read-only access the data in PostScript Printer
Description ("PPD") files which are used for all printers with a driver. With
it you can obtain the data necessary to display printer options to users, mark
option choices and check for conflicting choices, and output marked choices in
PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
structure contains all of the information in a PPD file.</p>
<blockquote><b>Note:</b>
<p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
values as case-insensitive strings, so option "InputSlot" and choice "Upper"
are equivalent to "inputslot" and "upper", respectively.</p>
</blockquote>
<h3><a name="LOADING">Loading a PPD File</a></h3>
<p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
PPD file and loads it into memory. For example, the following code opens the
current printer's PPD file in a CUPS filter:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
</pre>
<p>The return value is a pointer to a new
<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
if the PPD file does not exist or cannot be loaded. The
<a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
by the structure:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd;
<a href="#ppdClose">ppdClose</a>(ppd);
</pre>
<p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
structure and any data in it will no longer be valid.</p>
<h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
<p>PPD files support multiple options, which are stored in arrays of
<a href="#ppd_option_t"><code>ppd_option_t</code></a> and
<a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
<p>Each option in turn is associated with a group stored in a
<a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
specified in the PPD file; if an option is not associated with a group
then it is put in an automatically-generated "General" group. Groups can also
have sub-groups, however CUPS currently ignores sub-groups because of past
abuses of this functionality.</p>
<p>Option choices are selected by marking them using one of three functions. The
first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
selects all of the default options in the PPD file:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd;
<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
</pre>
<p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
which selects a single option choice in the PPD file. For example, the following
code selects the upper paper tray:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd;
<a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
</pre>
<p>The last function is
<a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
multiple option choices in the PPD file from an array of CUPS options, mapping
IPP attributes like "media" and "sides" to their corresponding PPD options. You
typically use this function in a print filter with
<code>cupsParseOptions</code> and
<a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
the option choices needed for the job, for example:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
cups_option_t *options = NULL;
int num_options = cupsParseOptions(argv[5], 0, &amp;options);
<a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
<a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
cupsFreeOptions(num_options, options);
</pre>
<h3><a name="CONSTRAINTS">Constraints</a></h3>
<p>PPD files support specification of conflict conditions, called
constraints, between different options. Constraints are stored in an array of
<a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
the options and choices that conflict with each other. The
<a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
how many of the selected options are incompatible. Since constraints are
normally specified in pairs, the returned value is typically an even number.</p>
<h3><a name="PAGE_SIZES">Page Sizes</a></h3>
<p>Page sizes are special options which have physical dimensions and margins
associated with them. The size information is stored in
<a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
by looking up the named size with the
<a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
margins are returned in units called points; there are 72 points per inch. If
you pass <code>NULL</code> for the size, the currently selected size is
returned:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd;
<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
</pre>
<p>Besides the standard page sizes listed in a PPD file, some printers
support variable or custom page sizes. Custom page sizes are supported if the
<code>variables_sizes</code> member of the
<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
The <code>custom_min</code>, <code>custom_max</code>, and
<code>custom_margins</code> members of the
<a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
of the printable area. To get the resulting media size, use a page size string
of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
in points. Custom page size names can also be specified in inches
("Custom.<i>width</i>x<i>height</i>in"), centimeters
("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
("Custom.<i>width</i>x<i>height</i>mm"):</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd;
/* Get an 576x720 point custom page size */
<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
/* Get an 8x10 inch custom page size */
<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
/* Get a 100x200 millimeter custom page size */
<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
/* Get a 12.7x34.5 centimeter custom page size */
<a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
</pre>
<p>If the PPD does not support variable page sizes, the
<a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
<code>NULL</code>.</p>
<h3><a name="ATTRIBUTES">Attributes</a></h3>
<p>Every PPD file is composed of one or more attributes. Most of these
attributes are used to define groups, options, choices, and page sizes,
however several informational attributes may be present which you can access
in your program or filter. Attributes normally look like one of the following
examples in a PPD file:</p>
<pre class="example">
*name: "value"
*name spec: "value"
*name spec/text: "value"
</pre>
<p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
<a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
first and next instances, respectively, of the named attribute with the given
"spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
structure. If you provide a NULL specifier string, all attributes with the
given name will be returned. For example, the following code lists all of the
<code>Product</code> attributes in a PPD file:</p>
<pre class="example">
#include &lt;cups/ppd.h&gt;
<a href="#ppd_file_t">ppd_file_t</a> *ppd;
<a href="#ppd_attr_t">ppd_attr_t</a> *attr;
for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
attr != NULL;
attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
puts(attr->value);
</pre>

It is not used by raster printer driver filters which only read CUPS
raster data.<br>
<br>
<code>cupsRasterInterpretPPD</code> does not mark the options in the PPD using
the &quot;num_options&quot; and &quot;options&quot; arguments. Instead, mark the options with
<code>cupsMarkOptions</code> and <code>ppdMarkOption</code> prior to calling it -
this allows for per-page options without manipulating the options array.<br>
<br>
The &quot;func&quot; argument specifies an optional callback function that is
called prior to the computation of the final raster data. The function
can make changes to the <a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a> data as needed to use a
supported raster format and then returns 0 on success and -1 if the
requested attributes cannot be supported.<br>
<br>
<code>cupsRasterInterpretPPD</code> supports a subset of the PostScript language.
Currently only the <code>[</code>, <code>]</code>, <code>&lt;&lt;</code>, <code>&gt;&gt;</code>, <code>{</code>,
<code>}</code>, <code>cleartomark</code>, <code>copy</code>, <code>dup</code>, <code>index</code>,

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