About LPD

Line Printer Daemon (LPD) refers to the protocol and programs associated with line-printer spooling services that may be installed on various TCP/IP systems.

Some of the widely used systems in which the HP Jetdirect print server functionality supports LPD include:

Berkeley-based (BSD) UNIX systems

HP-UX

Solaris

IBM AIX

Linux

Windows NT/2000

Mac OS

The UNIX configuration examples in this section show the syntax for BSD-based UNIX systems. The syntax for your system may vary. See your system documentation for the correct syntax.

Note

The LPD functionality can be used with any host

 

implementation of LPD that complies with the

 

RFC 1179 document. The process for configuring

 

printer spoolers, however, may differ. See your

 

system documentation for information on

 

configuring these systems.

 

 

The LPD programs and protocol include the following:
