<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><strong>Note:</strong></p>
- <p>CUPS printer drivers necessarily depend on specific file formats and certain implementation details of the CUPS software. Please consult the Postscript and raster printer driver developer documentation on <a href="https://www.cups.org/documentation.html">CUPS.org</a> for more information.</p>

- <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>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_DISCOVERED</code> for the <code>mask</code> argument. The following constants can be used for filtering:</p>
- <ul>
- <li><code>CUPS_PRINTER_CLASS</code>: A collection of destinations.</li>
- <li><code>CUPS_PRINTER_FAX</code>: A facsimile device.</li>
- <li><code>CUPS_PRINTER_LOCAL</code>: A local printer or class.

- <li><code>CUPS_PRINTER_COVER</code>: Can cover output.</li>
- <li><code>CUPS_PRINTER_BIND</code>: Can bind output.</li>
- <li><code>CUPS_PRINTER_SORT</code>: Can sort output (mailboxes, etc.)</li>
- <li><code>CUPS_PRINTER_SMALL</code>: Can print on Letter/Legal/A4-size media.</li>
- <li><code>CUPS_PRINTER_MEDIUM</code>: Can print on Tabloid/B/C/A3/A2-size media.</li>
