46 | The <b>cupsd-helper</b> programs perform long-running operations on behalf of the scheduler, | |
696f74ae | 47 | <b>cupsd</b>(8). |
f9988e18 | 48 | The <b>cups-deviced</b> helper program runs each CUPS |

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. | |
8072030b | 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: | |
55 | <pre class="man"> | |
56 | ||
57 | <i>/Library/Printers</i> | |
58 | <i>/opt/share/ppd</i> | |
59 | <i>/System/Library/Printers</i> | |
60 | <i>/usr/local/share/ppd</i> | |
61 | <i>/usr/share/cups/drv</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. | |
70 | <p>Driver information files must conform to the format defined in | |
87030afb MS |
71 | <b>ppdcfile</b>(5). |

73 | CUPS printer drivers, backends, and PPD files are deprecated and will no longer be supported in a future feature release of CUPS. | |
74 | Printers that do not support IPP can be supported using applications such as | |
75 | <b>ippeveprinter</b>(1). | |
