The cupsd-helper programs perform long-running operations
on behalf of the scheduler, cupsd(8)
. The cups-deviced helper program runs
each CUPS backend(7)
with no arguments in order to discover the available
printers.
The cups-driverd helper program lists all available printer drivers,
a subset of "matching" printer drivers, or a copy of a specific driver
PPD file.
The cups-exec helper program runs backends, filters, and other
programs. On OS X these programs are run in a secure sandbox.
The cups-driverd
program looks for PPD and driver information files in the following directories:
/Library/Printers
/opt/share/ppd
/System/Library/Printers
/usr/local/share/ppd
/usr/share/cups/drv
/usr/share/cups/model
/usr/share/ppd
PPD files can be compressed using the gzip(1)
program or placed in compressed
tar(1)
archives to further reduce their size.
Driver information files must
conform to the format defined in ppdcfile(5)
.
