  46 The <b>cupsd-helper</b> programs perform long-running operations on behalf of the scheduler,

  48 The <b>cups-deviced</b> helper program runs each CUPS
  49 <a href="man-backend.html?TOPIC=Man+Pages"><b>backend</b>(7)</a>
  50 with no arguments in order to discover the available printers.
  51 <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.
  52 <p>The <b>cups-exec</b> helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.
  53 <h2 class="title"><a name="FILES">Files</a></h2>
  54 The <b>cups-driverd</b> program looks for PPD and driver information files in the following directories:

  57     <i>/Library/Printers</i>
  58     <i>/opt/share/ppd</i>
  59     <i>/System/Library/Printers</i>
  60     <i>/usr/local/share/ppd</i>

  62     <i>/usr/share/cups/model</i>
  63     <i>/usr/share/ppd</i>
  64 </pre>
  65 <p>PPD files can be compressed using the
  66 <b>gzip</b>(1)
  67 program or placed in compressed
  68 <b>tar</b>(1)
  69 archives to further reduce their size.
