BlueZone TCP/IP Print Server is known as a Line Printer Daemon, or LPD for short. A "daemon" is a server or sometimes referred
to as an agent. BlueZone TCP/IP Print Server is an LPD Server.
LPR/LPD is a printing method used in many TCP/IP networks. It is in wide use on university and business campuses where IBM
Mainframe and iSeries system as well as UNIIX based systems have been in place for a long time. LPR/LPD is a computer-to-computer
printing method, rather than a Host-to-PC method.
The LPR/LPD protocol is broken into two parts: LPR and LPD.
LPR (Line Printer Request)
This is the part that submits the print request. LPR is the client part of the protocol and is sometimes confused when used
on a Mainframe. Any system submitting requests through an "LPR client" is referred to as a client.
LPD (Line Printer Daemon)
This is the piece that receives and processes the request. A "daemon" is a server or agent. BlueZone TCP/IP Print Server
is an LPD server.
The LPD Protocol Specification is documented in RFC 1179.
Use the BlueZone TCP/IP Print Server where your host system is running a Line Printer Request (LPR) client that is configured
to send print jobs to a specific end user IP address.
The BlueZone TCP/IP Print Server is a Line Printer Daemon (LPD) that runs on the end user's workstation that listens for print
jobs that are being sent directly to it by the LPR client.
