45 | .SH DESCRIPTION | |
46 | The \fBcupsd\-helper\fR programs perform long-running operations on behalf of the scheduler, | |
47 | .BR cupsd (8). | |
48 | The \fBcups-deviced\fR helper program runs each CUPS | |
49 | .BR backend (7) | |
50 | with no arguments in order to discover the available printers. | |
51 | .LP | |
52 | The \fBcups-driverd\fR helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file. | |
53 | .LP | |
54 | The \fBcups-exec\fR helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox. | |
55 | .SH FILES | |
56 | The \fBcups-driverd\fR program looks for PPD and driver information files in the following directories: | |
57 | .nf | |
58 | ||
59 | \fI/Library/Printers\fR | |
60 | \fI/opt/share/ppd\fR | |
61 | \fI/System/Library/Printers\fR | |
62 | \fI/usr/local/share/ppd\fR | |
63 | \fI/usr/share/cups/drv\fR | |
64 | \fI/usr/share/cups/model\fR | |
65 | \fI/usr/share/ppd\fR | |
66 | .fi | |
67 | .LP | |
68 | PPD files can be compressed using the | |
69 | .BR gzip (1) | |
70 | program or placed in compressed | |
71 | .BR tar (1) | |
72 | archives to further reduce their size. | |
73 | .LP | |
74 | Driver information files must conform to the format defined in | |
75 | .BR ppdcfile (5). | |
