Line 5:
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 [[Newline|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.<ref>[http://gpvno.co.za/ Winet]'s InetLPD server documentation.</ref>
A printer that supports LPD/LPR is sometimes referred to as a "TCP/IP printer" ([[Internet protocol suite|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]].
