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 2000
■ Windows Server 2003
■ 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:
Table A-1 LPD Programs and Protocols
Program Name Purpose of Program
lpr Queues jobs for printing
lpq Displays print queues
lprm Removes jobs from print queues
lpc Controls print queues
lpd Scans and prints the files if the specified printer is connected to the system.
If the specified printer is connected to another system, this process forwards the files to
an lpd process on the remote system where the files are to be printed.
Requirements for Configuring LPD
Before you can use LPD printing, your printer must be properly connected to the network through the
HP Jetdirect print server, and you must have print server status information. This information is listed
