<h2 class="title"><a name="DESCRIPTION">Description</a></h2>
The <b>cupsd-helper</b> programs perform long-running operations on behalf of the scheduler,
<b>cupsd</b>(8).
The <b>cups-deviced</b> helper program runs each CUPS
<b>backend</b>(7)
with no arguments in order to discover the available printers.
<p>The <b>cups-driverd</b> helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file.
<p>The <b>cups-exec</b> helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.
<h2 class="title"><a name="FILES">Files</a></h2>
The <b>cups-driverd</b> program looks for PPD and driver information files in the following directories:
<pre class="man">
<i>/Library/Printers</i>
<i>/opt/share/ppd</i>
<i>/System/Library/Printers</i>
<i>/usr/local/share/ppd</i>
<i>/usr/share/cups/drv</i>
<i>/usr/share/cups/model</i>
<i>/usr/share/ppd</i>
</pre>
<p>PPD files can be compressed using the
<b>gzip</b>(1)
program or placed in compressed
<b>tar</b>(1)
archives to further reduce their size.
<p>Driver information files must conform to the format defined in
<b>ppdcfile</b>(5).
<h2 class="title"><a name="NOTES">Notes</a></h2>
CUPS printer drivers, backends, and PPD files are deprecated and will no longer be supported in a future feature release of CUPS.
Printers that do not support IPP can be supported using applications such as
<b>ippeveprinter</b>(1).
