What is LPR/LPD?
LPR/LPD is the printing method most commonly used in TCP/IP networks. It is in use on university and business campuses where UNIX, AS/400 and mainframe systems have been in place for a while; the new generation of operating systems, for both mainframe and desktop, now support TCP/IP and LPD as well. It is a computer-to-computer printing method, rather than PC-to-PC. The LPR/LPD protocol is broken into two parts, LPR and LPD. The standard LPD port is 515. LPR is an acronym for Line Printer Request; this is the part that submits the print request. LPR is the client part of the protocol and is sometimes confused when used on a mainframe. Any system submitting requests via an “LPR client” is a client. INTELLIscribe is an LPR client. LPD stands for Line Printer Daemon; this is the piece that receives and processes the request. A “daemon” is a server or agent. RPM is a LPR/LPD server. The LPD Protocol Specification is documented in RFC 1179, Line Printer Daemon Protocol, dated August 1990, e
