Line Printer Remote: A printer protocol that uses TCP/IP to establish connections between printers and workstations on a network. The technology was developed originally for BSD UNIX and has since become the de facto cross-platform printing protocol.

Consider the following scenario:

• You are using a computer that is running Windows Vista, Windows Server 2003, or Windows XP.
• You try to print to a Line Printer Remote (LPR) printer by using LPR port monitor software or TCP/IP port monitor software.

In this scenario, you experience slow printing performance.
