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).
