Throughout chapter 'The LPD connection', the following terminology is used:
LP refers to the entire Line Printer architecture/system, consisting of client applications, server applications, print queues, and communication protocol.
LPD (upper case) refers to the protocol (RFC 1179) which is used to communicate between host and printer.
lpd (lower case) refers to the application which services LPD requests from the (local or remote) host system. This is generally called the LPD server.
printerlpd is the printer-specific version of lpd.
User An lpd user may be a human operator, but is more likely to be a application running on the user’s workstation, which communicates with the varioPRINT 140 Series. Therefore, in this chapter, the user is always addressed in the third person.
