System V printing system

The printing subsystem of UNIX System V is one of several standardized systems for printing on Unix, and is typical of commercial System V-based Unix versions such as Solaris and SCO OpenServer. A system running this print architecture could traditionally be identified by the use of the user command lp as the primary interface to the print system, as opposed to the BSD lpr command (though some systems provide lpr as an alias to lp).

Typical user commands available to the System V printing system are:

• lp: the user command to print a document
• lpstat: shows the current print queue
• cancel: deletes a job from the print queue
• lpadmin: a system administration command that configures the print system
• lpmove: a system administration command that moves jobs between print queues
