Receive print jobs and report printer status to LPD clients

cups-lpd is the CUPS Line Printer Daemon mini-server that supports legacy client systems that use the LPD protocol. cups-lpd does not act as a standalone network daemon but instead operates using any of the Internet 'super-servers' such as inetd, launchd, and systemd.
