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

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