About LPD

Line printer daemon (LPD) refers to the protocol and programs associated with line-printer spooling services that are typically installed on various TCP/IP systems.

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

Berkeley-based (BSD) UNIX systems

HP-UX

Solaris

IBM AIX

Linux

Microsoft Windows Server 2003/2008

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

NOTE: Use LPD functionality with any host implementation that complies with the RFC 1179 document. The process for configuring printer spoolers, however, might differ. See your system documentation for information on configuring these systems.

The LPD programs and protocol include the following:

Table A-1LPD programs and protocols

Program Name

Purpose of Program

 

 

lpr

Queue jobs for printing

 

 

lpq

Display print queues

 

 

lprm

Remove jobs from print queues

 

 

lpc

Control print queues

 

 

lpd

Scan and print 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

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 on the HP Jetdirect printer configuration page. If you have not printed a configuration page from your printer, see your printer documentation for instructions. You must also have the following:

Operating system that supports LPD printing.

Superuser (root) or administrator access to your system.

LAN hardware address (or station address) of the print server. This address is displayed with print server status information on the HP Jetdirect configuration page and is of the form:
