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.

Uses the named cupsd.conf configuration file.
Run cupsd in the foreground; the default is to run in the background as a "daemon".
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).

This option is passed to cupsd when it is run from launchd(8) or systemd(8).
Uses the named cups-files.conf configuration file.
Test the configuration file for syntax errors.
