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).
