What is RFC 1179, the Line Printer Daemon Protocol?
RFC1179 defines a standard method by which print jobs can be transferred using the TCP/IP protocol between hosts. The standard was developed by simply detailing the way that a version of the BSD LPD software did its job. From the RFC Introduction: RFC 1179 describes a print server protocol widely used on the Internet for communicating between line printer daemons (both clients and servers). RFC1179 is for informational purposes only, and does not specify an Internet standard. Having said this, the RFC then goes on to describe the protocol used by a particular implementation of LPD. The problem was that the RFC did not provide any way to put extensions to the operations into the system, and failed to specify such interesting details as the order in which print jobs and their components could be transferred.
