LPRng
LPRng is a printing system compatible with the Berkeley printing system. It provides printer spooling and network print server functionality using the Line Printer Daemon protocol.
It is an open-source project hosted on SourceForge and implemented by many open-source Unix-like operating systems. LPRng was abandoned by its author in early 2005, then picked back up by new developers in October 2006. A new release was made available in December 2006 (LPRng-3.8.29 RC 1).
The latest release is 3.8.C, which was made available on May 09, 2013.
