The '''Berkeley printing system''' is one of several standard architectures for printing on the [[Unix]] platform.<ref name=":0">{{Cite manual |url=https://www.office.xerox.com/support/dctips/dc99cc25.pdf |title=BSD vs. System V Printing |date=November 25, 2003 |publisher=[[Xerox|Xerox Multifunction Devices]] |access-date=April 4, 2025}}</ref> It originated in [[2.10BSD]],{{Citation needed|date=April 2025|reason=Cannot find a source supporting its introduction in 2.10BSD}} and is still used to varying degrees in [[Berkeley Software Distribution|BSD]] derivatives such as [[FreeBSD]],<ref>{{Cite web |date=June 6, 1993 |title=LPR(1) |url=https://man.freebsd.org/cgi/man.cgi?query=lpr&sektion=1&format=html |access-date=April 4, 2025 |website=FreeBSD Manual Pages |publisher=[[FreeBSD|The FreeBSD Project]]}}</ref><ref>{{Cite web |date=April 15, 2021 |title=LPD(8) |url=https://man.freebsd.org/cgi/man.cgi?query=lpd&sektion=8&format=html |access-date=April 4, 2025 |website=FreeBSD Manual Pages |publisher=[[FreeBSD|The FreeBSD Project]]}}</ref> [[NetBSD]],<ref>{{Cite manual |title=The NetBSD Guide |publisher=[[NetBSD|The NetBSD Foundation]] |year=2025 |chapter=Chapter 12.

Typical user commands available to the Berkeley print system are:

*''lpr'' — the user command to assign a job to the [[Print job|print queue]]<ref name=":0" /><ref name=":1" />
*''lpq'' — shows the current print queue<ref name=":0" /><ref name=":1" />
*''lprm'' — deletes a job from the print queue<ref name=":0" /><ref name=":1" />

The ''lpd'' program is the [[Daemon (computing)|daemon]] with which those programs communicate.<ref name=":0" />

These programs support the [[Line Printer Daemon protocol|line printer daemon protocol]], so that other machines on a network can submit jobs to a print queue on a machine running the Berkeley printing system, and so that the Berkeley printing system user commands can submit jobs to machines that support that protocol.<ref name=":0" /><ref>{{Cite IETF|rfc=1179|title=Line Printer Daemon Protocol|first1=Leo|last1=McLaughlin|url=https://datatracker.ietf.org/doc/html/rfc1179|date=August 1990|publisher=[[Internet Engineering Task Force|IETF]]|access-date=April 4, 2025}}</ref>
