The line printer system supports:
multiple spooling queues,
printers attached via serial lines that require
line initialization such as the baud rate.
such as a Varian or Versatec, and laser printers such as an Imagen,
are also supported by the line printer system.
The line printer system consists mainly of the
following files and commands:
/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
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
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
