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).
