NAME
lpc - line printer control program
SYNOPSIS
/etc/lpc [ command [ argument ... ] ]
DESCRIPTION
_L_p_c is used by the system administrator to control the
operation of the line printer system. For each line printer
configured in /etc/printcap, _l_p_c may be used to:
o+ disable or enable a printer,
o+ disable or enable a printer's spooling queue,
o+ rearrange the order of jobs in a spooling queue,
o+ find the status of printers, and their associated
spooling queues and printer dameons.
Without any arguments, _l_p_c will prompt for commands from the
standard input. If arguments are supplied, _l_p_c interprets
the first argument as a command and the remaining arguments
as parameters to the command. The standard input may be
redirected causing _l_p_c to read commands from file. Commands
may be abreviated; the following is the list of recognized
commands.
? [ command ... ]
help [ command ... ]
Print a short description of each command specified in
the argument list, or, if no arguments are given, a
list of the recognized commands.
abort { all | printer ... }
Terminate an active spooling daemon on the local host
immediately and then disable printing (preventing new
daemons from being started by _l_p_r) for the specified
printers.
clean { all | printer ... }
Remove any temporary files, data files, and control
files that cannot be printed (i.e., do not form a com-
plete printer job) from the specified printer queue(s)
on the local machine.
disable { all | printer ... }
Turn the specified printer queues off. This prevents
new printer jobs from being entered into the queue by
_l_p_r.

down { all | printer } message ...
Turn the specified printer queue off, disable printing
and put _m_e_s_s_a_g_e in the printer status file. The message
doesn't need to be quoted, the remaining arguments are
treated like _e_c_h_o(1). This is normally used to take a
printer down and let others know why (lpq will indicate
the printer is down and print the status message).
enable { all | printer ... }
Enable spooling on the local queue for the listed
printers. This will allow _l_p_r to put new jobs in the
spool queue.
exit
quit
Exit from lpc.
restart { all | printer ... }
Attempt to start a new printer daemon. This is useful
when some abnormal condition causes the daemon to die
unexpectedly leaving jobs in the queue. _L_p_q will
report that there is no daemon present when this condi-
tion occurs. If the user is the super-user, try to
abort the current daemon first (i.e., kill and restart
a stuck daemon).
start { all | printer ... }
Enable printing and start a spooling daemon for the
listed printers.
status { all | printer ... }
Display the status of daemons and queues on the local
machine.
stop { all | printer ... }
Stop a spooling daemon after the current job completes
and disable printing.
topq printer [ jobnum ... ] [ user ... ]
Place the jobs in the order listed at the top of the
printer queue.
up { all | printer ... }
Enable everything and start a new printer daemon.
Undoes the effects of _d_o_w_n.
