The lpr command is the traditional (legacy BSD-style) CUPS utility used to send files to a printer queue from the command line. In contrast, lpq reports the status of jobs in a queue, lpd is the legacy line printer daemon that runs on the server side to receive print jobs, and lpp is not a standard printing command. CUPS maintains these legacy commands for backward compatibility with traditional UNIX printing systems.
