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-1 LPD 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:
