The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) is a network protocol for submitting print jobs to a remote printer. The original implementation of LPD was in the Berkeley printing system in the BSD UNIX operating system; the LPRng project also supports that protocol. The Common Unix Printing System (or CUPS), which is more common on modern Linux distributions, supports LPD as well as the Internet Printing Protocol (IPP). Commercial solutions are available that also leverage Berkeley printing protocol components, where more robust functionality and performance is necessary than is available from LPR/LPD (or CUPS) alone (such as might be required in large corporate environments). The LPD Protocol Specification is documented in RFC 1179.[1]

Usage [link]
A server for the LPD protocol listens for requests on TCP port 515. A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character.
An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue names may exist in one LPD server, with each queue having unique settings. Note that the LPD queue name is case sensitive. Some modern implementations of LPD on network printers might ignore the case or queue name altogether and send all jobs to the same printer. Others have the option to automatically create a new queue when a print job with a new queue name is received. This helps to simplify the setup of the LPD server.[2] Some companies (e.g. D-Link in model DP-301P+) have a tradition of calling the queue name “lpt1” or “LPT1”.
A printer that supports LPD/LPR is sometimes referred to as a "TCP/IP printer" (TCP/IP is used to establish connections between printers and clients on a network), although that term would be equally applicable to a printer that supports the Internet Printing Protocol.

LPR (cycling team)
LPR Brakes (UCI team code: LPR) was a UCI Professional Continental cycling team, registered in Ireland. The team participated in UCI Continental Circuits races and, when selected as a wildcard, UCI ProTour events. The 2007 squad merged with Team 3C Casalinghi Jet Androni Giocattoli. The team was managed by Davide Boifava in the 2007 season but Fabio Bordonali acquired the management in late 2007.Giovanni Fidanza, Mario Manzoni, and Marco Giuseppe Tabai were directeur sportifs. The team folded after the 2009 season.
