NAME

       cupsd-helper - cupsd helper programs (deprecated)

SYNOPSIS

       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

       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.

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 compressed tar(1) archives to further reduce their size.

       Driver information files must conform to the format defined in
       ppdcfile(5).

NOTES

       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).
