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 which are supported by your all-in-one using LPD include:
●
Berkeley-based (BSD) UNIX systems
●
HP-UX
●
Solaris
●
IBM AIX
●
Linux
●
Windows NT/2000/XP
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 about configuring these systems.
The LPD programs and protocol include the following:
Table 9-6 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 all-in-one is connected to the system.
If the specified all-in-one 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.
