LPR clients always send a 'control file' (actually, a data structure within the print job) containing administrative information with each print job. LPD receives jobs from LPR clients and submits them to the spooler. Protocol reports the same error condition. If anything goes wrong, from severe problems (such as the server being too busy to process requests) to print-device problems (such as running out of paper), the LPR The LPR protocol does not pass detailed error status information back to the LPR client. NT 4.0 LPR print jobs are sourced from any available reserved port between 5. If enough jobs were sent in quick succession the ports could become a bottleneck causing a delay. Windows NT 3.5 x sent all TCP/IP print jobs from Windows NT computers from TCP ports 721 through 731. Windows NT now supports multiple data files per control file, and when used in 'print through' mode as an intermediate spooler, it correctly passes the hostname parameter Windows NT 4.0 has added enhancements to support the most popular and requested options. Of Windows NT supported TCP/IP printing as documented in RFC 1179, which describes an existing print server protocol widely used on the Internet for communicating between line printer daemons but does not specify an Internet standard.

The LPR standard is published as Request For Comment (RFC) 1179. It was originally developed as a standard for transmitting print jobs between computers running Berkeley UNIX. LPR is one of the network protocols in the TCP/IP protocol suite. LPR clients are often on UNIX systems, but LPR software exists for most operating systems, including Windows NT. LPD receives print jobs from line printer remote (LPR) clients. The TCP/IP Print service is generally referred to as LPD, which stands for If your print device supports the LPD service, you can also use lpr.exe to send the job to the IP of the device. As MYousufAli points out, you can print to the local SHARED printer.
