cupsd-helper(8)              (CUPS)               cupsd-helper(8)

     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 informa-
          tion 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).
