cupsd-helper

cupsd-helper(8) 						    Apple Inc.							   cupsd-helper(8)

NAME

       cupsd-helper - cupsd helper programs

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).
