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).

NAME

       cupsd - cups scheduler

SYNOPSIS

       cupsd [ -c cupsd.conf ] [ -f ] [ -F ] [ -h ] [ -l ] [ -s cups-files.conf ] [ -t ]

DESCRIPTION

       cupsd  is the scheduler for CUPS. It implements a printing system based upon the Internet Printing Protocol, version 2.1, and supports most
       of the requirements  for  IPP  Everywhere.  If  no  options  are  specified  on	the  command-line  then  the  default  configuration  file
       /etc/cups/cupsd.conf will be used.

OPTIONS

       -c cupsd.conf
	    Uses the named cupsd.conf configuration file.

       -f   Run cupsd in the foreground; the default is to run in the background as a "daemon".

       -F   Run  cupsd	in  the  foreground but detach the process from the controlling terminal and current directory. This is useful for running
	    cupsd from init(8).

       -h   Shows the program usage.

       -l   This option is passed to cupsd when it is run from launchd(8) or systemd(8).

       -s cups-files.conf
	    Uses the named cups-files.conf configuration file.

       -t   Test the configuration file for syntax errors.

FILES

       /etc/cups/classes.conf
       /etc/cups/cups-files.conf
       /etc/cups/cupsd.conf
       /usr/share/cups/mime/mime.convs
       /usr/share/cups/mime/mime.types
       /etc/cups/printers.conf
       /etc/cups/subscriptions.conf

CONFORMING TO

       cupsd implements all of the required IPP/2.1 attributes and operations. It also implements several CUPS-specific administrative operations.

EXAMPLES

       Run cupsd in the background with the default configuration file:

	   cupsd

       Test a configuration file called test.conf:

	   cupsd -t -c test.conf

       Run cupsd in the foreground with a test configuration file called test.conf:

	   cupsd -f -c test.conf
