.SH NAME
lpc \- line printer control program
.SH SYNOPSIS
.B /etc/lpc
[ command [ argument ... ] ]
.SH DESCRIPTION
.I Lpc
is used by the system administrator to control the
operation of the line printer system.  
For each line printer configured in /etc/printcap,
.I lpc
may be used to:
.IP \(bu
disable or enable a printer,
.IP \(bu
disable or enable a printer's spooling queue,
.IP \(bu
rearrange the order of jobs in a spooling queue,
.IP \(bu
find the status of printers, and their associated
spooling queues and printer dameons.
.PP
Without any arguments,
.I lpc
will prompt for commands from the standard input.
If arguments are supplied,
.IR lpc
interprets the first argument as a command and the remaining
arguments as parameters to the command.  The standard input
may be redirected causing
.I lpc
to read commands from file.
Commands may be abreviated;
the following is the list of recognized commands.
