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 macOS 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).
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
ippeveprinter(1).
