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).
