LPR / LPD ( Line Printer Daemon protocol / Line Printer Remote protocol)

The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) also known as the Berkeley printing system, is a set of programs that provide printer spooling and network print server functionality for Unix-like systems. The most common implementations of LPD are the official BSD UNIX operating system and the LPRng project. The Common Unix Printing System (or CUPS), which is more common on modern Linux distributions, borrows heavily from LPD.
DocFamily supports LPR/LPD in its DocBase server as a standard input- and output channel.
DocBase can act as a “Line Printer Daemon” and receives prints from a client. This feature is commonly used to support “Office-In”, meaning that any office application can send a print-file to DocBase for post-processing.
DocBase also can send a print-file to a third-party Print-Spooler using LPR.
