DESCRIPTION
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 pro-
grams. On macOS these programs are run in a secure sandbox.
FILES
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 com-
tar(1) archives to further reduce their size.
Driver information files must conform to the format defined in ppdc-
file(5).
