| <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). |
