NAME         top

       cupsd-helper - cupsd helper programs

SYNOPSIS         top

       cups-deviced request-id limit user-id options
       cups-driverd cat ppd-name
       cups-driverd list request_id limit options
       cups-exec sandbox-profile [ -g group-id ] [ -n nice-value ] [ -u
       user-id ] /path/to/program argv0 ...  argvN

DESCRIPTION         top

       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).
