NAME
cupsd-helper - cupsd helper programs (deprecated)
SYNOPSIS
cups-deviced request-id limit user-id options

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 print-
ers.
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 com-
pressed tar(1) archives to further reduce their size.
Driver information files must conform to the format defined in ppdc-
file(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).
