Overview
|
|
.PP
|
|
The line printer system supports:
|
|
.IP \(bu 3
|
|
multiple printers,
|
|
.IP \(bu 3
|
|
multiple spooling queues,
|
|
.IP \(bu 3
|
|
both local and remote
|
|
printers, and
|
|
.IP \(bu 3
|
|
printers attached via serial lines that require
|
|
line initialization such as the baud rate.
|
|
.LP
|
|
Raster output devices
|
|
such as a Varian or Versatec, and laser printers such as an Imagen,
|
|
are also supported by the line printer system.
|
|
.PP
|
|
The line printer system consists mainly of the
|
|
following files and commands:
|
|
.DS
|
|
.TS
|
|
l l.
|
|
/etc/printcap printer configuration and capability data base
|
|
/usr/lib/lpd line printer daemon, does all the real work
|
|
/usr/ucb/lpr program to enter a job in a printer queue
|
|
/usr/ucb/lpq spooling queue examination program
|
|
/usr/ucb/lprm program to delete jobs from a queue
|
|
/etc/lpc program to administer printers and spooling queues
|
|
/dev/printer socket on which lpd listens
|
|
.TE
|
|
.DE
|
|
The file /etc/printcap is a master data base describing line
|
|
printers directly attached to a machine and, also, printers
|
|
accessible across a network. The manual page entry
|
|
.IR printcap (5)
|
|
provides the authoritative definition of
|
|
the format of this data base, as well as
|
|
specifying default values for important items
|
|
such as the directory in which spooling is performed.
|
|
This document introduces some of the
|
|
information that may be placed
|
|
.IR printcap .
