<p>CUPS provides the "cups" library to talk to the different parts of CUPS and with Internet Printing Protocol (IPP) printers. The "cups" library functions are accessed by including the <code><cups/cups.h></code> header.</p>
<p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows clients (applications) to communicate with a server (the scheduler, printers, etc.) to get a list of destinations, send print jobs, and so forth. You identify which server you want to communicate with using a pointer to the opaque structure <code>http_t</code>. The <code>CUPS_HTTP_DEFAULT</code> constant can be used when you want to talk to the CUPS scheduler.</p>
- <h3><a id="Guidelines">Guidelines</a></h3>
+ <h3><a id="guidelines">Guidelines</a></h3>
<p>When writing software that uses the "cups" library:</p>
<ul>
<li>Do not use undocumented or deprecated APIs,</li>
</ul>
<p>CUPS is designed to insulate users and developers from the implementation details of printers and file formats. The goal is to allow an application to supply a print file in a standard format with the user intent ("print four copies, two-sided on A4 media, and staple each copy") and have the printing system manage the printer communication and format conversion needed.</p>
<p>Similarly, printer and job management applications can use standard query operations to obtain the status information in a common, generic form and use standard management operations to control the state of those printers and jobs.</p>

<p>A <em>Destination</em> is a printer or print queue that accepts print jobs. A <em>Print</em> <em>Job</em> is one or more documents that are processed by a destination using options supplied when creating the job. A <em>Document</em> is a file (JPEG image, PDF file, etc.) suitable for printing. An <em>Option</em> controls some aspect of printing, such as the media used. <em>Media</em> is the sheets or roll that is printed on. An <em>Attribute</em> is an option encoded for an Internet Printing Protocol (IPP) request.</p>

<p>The CUPS libraries can be used from any C, C++, or Objective C program. The method of compiling against the libraries varies depending on the operating system and installation of CUPS. The following sections show how to compile a simple program (shown below) in two common environments.</p>
<p>The following simple program lists the available destinations:</p>
<pre><code>#include <stdio.h>
return (0);
}
</code></pre>
- <h4><a id="CompilingwithXcode">Compiling with Xcode</a></h4>
+ <h4><a id="compiling-with-xcode">Compiling with Xcode</a></h4>
<p>In Xcode, choose <em>New</em> <em>Project...</em> from the <em>File</em> menu (or press SHIFT+CMD+N), then select the <em>Command</em> <em>Line</em> <em>Tool</em> under the macOS Application project type. Click <em>Next</em> and enter a name for the project, for example "firstcups". Click <em>Next</em> and choose a project directory. The click <em>Next</em> to create the project.</p>
<p>In the project window, click on the <em>Build</em> <em>Phases</em> group and expand the <em>Link</em> <em>Binary</em> <em>with</em> <em>Libraries</em> section. Click <em>+</em>, type "libcups" to show the library, and then double-click on <code>libcups.tbd</code>.</p>
<p>Finally, click on the <code>main.c</code> file in the sidebar and copy the example program to the file. Build and run (CMD+R) to see the list of destinations.</p>
- <h4><a id="CompilingwithGCC">Compiling with GCC</a></h4>
+ <h4><a id="compiling-with-gcc">Compiling with GCC</a></h4>
<p>From the command-line, create a file called <code>sample.c</code> using your favorite editor, copy the example to this file, and save. Then run the following command to compile it with GCC and run it:</p>
<pre><code>gcc -o simple `cups-config --cflags` simple.c `cups-config --libs`
./simple
</code></pre>
<p>The <code>cups-config</code> command provides the compiler flags (<code>cups-config --cflags</code>) and libraries (<code>cups-config --libs</code>) needed for the local system.</p>
- <h2><a id="WorkingwithDestinations">Working with Destinations</a></h2>
+ <h2><a id="working-with-destinations">Working with Destinations</a></h2>
<p>Destinations, which in CUPS represent individual printers or classes (collections or pools) of printers, are represented by the <code>cups_dest_t</code> structure which includes the name (<code>name</code>), instance (<code>instance</code>, saved options/settings), whether the destination is the default for the user (<code>is_default</code>), and the options and basic information associated with that destination (<code>num_options</code> and <code>options</code>).</p>
<p>Historically destinations have been manually maintained by the administrator of a system or network, but CUPS also supports dynamic discovery of destinations on the current network.</p>
- <h3><a id="FindingAvailableDestinations">Finding Available Destinations</a></h3>
+ <h3><a id="finding-available-destinations">Finding Available Destinations</a></h3>
<p>The <code>cupsEnumDests</code> function finds all of the available destinations:</p>
<pre><code> int
cupsEnumDests(unsigned flags, int msec, int *cancel,
<p>The <code>flags</code> argument specifies enumeration options, which at present must be <code>CUPS_DEST_FLAGS_NONE</code>.</p>
<p>The <code>msec</code> argument specifies the maximum amount of time that should be used for enumeration in milliseconds - interactive applications should keep this value to 5000 or less when run on the main thread.</p>
<p>The <code>cancel</code> argument points to an integer variable that, when set to a non-zero value, will cause enumeration to stop as soon as possible. It can be <code>NULL</code> if not needed.</p>
- <p>The <code>type</code> and <code>mask</code> arguments are bitfields that allow the caller to filter the destinations based on categories and/or capabilities. The destination's "printer-type" value is masked by the <code>mask</code> value and compared to the <code>type</code> value when filtering. For example, to only enumerate destinations that are hosted on the local system, pass <code>CUPS_PRINTER_LOCAL</code> for the <code>type</code> argument and <code>CUPS_PRINTER_REMOTE</code> for the <code>mask</code> argument. The following constants can be used for filtering:</p>

The following names are predefined for various destination attributes:</p>
<ul>
<li>"auth-info-required": The type of authentication required for printing to this destination: "none", "username,password", "domain,username,password", or "negotiate" (Kerberos).</li>
<li>"printer-state-change-time": The UNIX time when the destination entered the current state.</li>
<li>"printer-state-reasons": Additional comma-delimited state keywords for the destination such as "media-tray-empty-error" and "toner-low-warning".</li>
<li>"printer-type": The <code>cups_ptype_t</code> value associated with the destination.</li>
+ <li>"printer-uri-supported": The URI associated with the destination; if not set, this destination was discovered but is not yet setup as a local printer.</li>
</ul>
<p>Use the <code>cupsGetOption</code> function to retrieve the value. For example, the following code gets the make and model of a destination:</p>
<pre><code>const char *model = cupsGetOption("printer-make-and-model",
dest->num_options,
dest->options);
</code></pre>
- <h3><a id="DetailedDestinationInformation">Detailed Destination Information</a></h3>
+ <h3><a id="detailed-destination-information">Detailed Destination Information</a></h3>
<p>Once a destination has been chosen, the <code>cupsCopyDestInfo</code> function can be used to gather detailed information about the destination:</p>
<pre><code>cups_dinfo_t *
cupsCopyDestInfo(http_t *http, cups_dest_t *dest);
</code></pre>
<p>The <code>http</code> argument specifies a connection to the CUPS scheduler and is typically the constant <code>CUPS_HTTP_DEFAULT</code>. The <code>dest</code> argument specifies the destination to query.</p>
<p>The <code>cups_dinfo_t</code> structure that is returned contains a snapshot of the supported options and their supported, ready, and default values. It also can report constraints between different options and values, and recommend changes to resolve those constraints.</p>
- <h4><a id="GettingSupportedOptionsandValues">Getting Supported Options and Values</a></h4>
+ <h4><a id="getting-supported-options-and-values">Getting Supported Options and Values</a></h4>
<p>The <code>cupsCheckDestSupported</code> function can be used to test whether a particular option or option and value is supported:</p>
<pre><code>int
cupsCheckDestSupported(http_t *http, cups_dest_t *dest,
for (i = 0; i < count; i ++)
puts(ippGetString(attrs, i, NULL));
</code></pre>
- <h4><a id="GettingDefaultValues">Getting Default Values</a></h4>
+ <h4><a id="getting-default-values">Getting Default Values</a></h4>
<p>There are two sets of default values - user defaults that are available via the <code>num_options</code> and <code>options</code> members of the <code>cups_dest_t</code> structure, and destination defaults that available via the <code>cups_dinfo_t</code> structure and the <code>cupsFindDestDefault</code> function which returns the IPP attribute containing the default value(s) for a given option:</p>
<pre><code>ipp_attribute_t *
cupsFindDestDefault(http_t *http, cups_dest_t *dest,
putchar('\n');
}
</code></pre>
- <h4><a id="GettingReadyLoadedValues">Getting Ready (Loaded) Values</a></h4>
+ <h4><a id="getting-ready-loaded-values">Getting Ready (Loaded) Values</a></h4>
<p>The finishings and media options also support queries for the ready, or loaded, values. For example, a printer may have punch and staple finishers installed but be out of staples - the supported values will list both punch and staple finishing processes but the ready values will only list the punch processes. Similarly, a printer may support hundreds of different sizes of media but only have a single size loaded at any given time - the ready values are limited to the media that is actually in the printer.</p>
<p>The <code>cupsFindDestReady</code> function finds the IPP attribute containing the ready values for a given option:</p>
<pre><code>ipp_attribute_t *
else
puts("no finishings are ready.");
</code></pre>
- <h4><a id="MediaSizeOptions">Media Size Options</a></h4>
+ <h4><a id="media-size-options">Media Size Options</a></h4>
<p>CUPS provides functions for querying the dimensions and margins for each of the supported media size options. The <code>cups_size_t</code> structure is used to describe a media size:</p>
<pre><code>typedef struct cups_size_s
{
cups_dinfo_t *dinfo, unsigned flags,
cups_size_t *size);
</code></pre>
- <h4><a id="LocalizingOptionsandValues">Localizing Options and Values</a></h4>
+ <h4><a id="localizing-options-and-values">Localizing Options and Values</a></h4>
<p>CUPS provides three functions to get localized versions of options and values: <code>cupsLocalizeDestMedia</code>, <code>cupsLocalizeDestOption</code>, and <code>cupsLocalizeDestValue</code>:</p>
<pre><code>const char *
cupsLocalizeDestMedia(http_t *http, cups_dest_t *dest,
cups_dinfo_t *info,
const char *option, const char *value);
</code></pre>
- <h3><a id="SubmittingaPrintJob">Submitting a Print Job</a></h3>
+ <h3><a id="submitting-a-print-job">Submitting a Print Job</a></h3>
<p>Once you are ready to submit a print job, you create a job using the <code>cupsCreateDestJob</code> function:</p>

cupsCreateDestJob(http_t *http, cups_dest_t *dest,
