lpc(1B) SunOS/BSD Compatibility Package Commands lpc(1B)NAMElpc - line printer control program
SYNOPSIS
/usr/ucb/lpc [command [parameter...]]
DESCRIPTION
The lpc utility controls the operation of local printers.
Use lpc to perform the following functions:
o start or stop a printer,
o disable or enable a printer's spooling queue,
o rearrange the order of jobs in a print queue, or
o display the status of a printer print queue and printer dae‐
mon.
lpc can be run from the command line or interactively. Specifying lpc
with the optional command andparameter arguments causes lpc to inter‐
pret the first argument as an lpc command, and all other arguments as
parameters to that command. Specifying lpc without arguments causes it
to run interactively, prompting the user for lpc commands with lpc>. By
redirecting the standard input, lpc can read commands from a file.
USAGElpc commands can be typed in their entirety or abbreviated to an unam‐
biguous substring. Some lpc commands are available to all users; others
are available only to super-users.
All users can execute the following lpc commands:
? [command ...] | help [command ...]
Displays a short description of command. command is an lpc command.
If command is not specified, displays a list of lpc commands.
exit | quit
Exits from lpc.
status [all | printer...]
Displays the status of print daemons and print queues. all speci‐
fies that this command is performed on all locally attached print‐
ers. printer indicates this command is performed on specific print‐
ers. Specify printer as an atomic name. See printers.conf(4) for
information regarding naming conventions for atomic names.
Only a super-user can execute the following lpc commands:
abort [all | printer...]
Terminates an active spooling daemon. Disables printing (by pre‐
venting new daemons from being started by lpr(1B)) for printer. all
specifies this command is performed on all locally attached print‐
ers. printer indicates this command is performed on specific print‐
ers. Specify printer as an atomic name. See printers.conf(4) for
information regarding naming conventions for atomic names.
clean [all | printer...]
Removes files created in the print spool directory by the print
daemon from printer 's print queue. all specifies that this command
is performed on all locally attached printers.printer indicates
this command is performed on specific printers. Specify printer as
an atomic name. See printers.conf(4) for information regarding nam‐
ing conventions for atomic names.
disable [all | printer ...]
Turns off the print queue for printer. Prevents new printer jobs
from being entered into the print queue for printerby lpr(1B). all
specifies that this command is performed on all locally attached
printers. printer indicates this command is performed on specific
printers. Specify printer as an atomic name. See printers.conf(4)
for information regarding naming conventions for atomic names.
down [all | printer ...] [message]
Turns the queue for printer off and disables printing on printer.
Inserts message in the printer status file. message does not need

ers.conf(4) for information regarding naming conventions for atomic
names.
enable [all | printer ...]
Enables lpr(1B) to add new jobs in the spool queue. all specifies
that this command is performed on all locally attached printers.
printer indicates this command is performed on specific printers.
Specify printer as an atomic name. See printers.conf(4) for infor‐
mation regarding naming conventions for atomic names.
restart [all | printer...]
Attempts to start a new printer daemon. restart is useful when a
print daemon dies unexpectedly and leaves jobs in the print queue.
all specifies that this command is performed on all locally
attached printers. printer indicates that this command is performed
on specific printers. Specify printer as an atomic name. See print‐
ers.conf(4) for information regarding naming conventions for atomic
names.
start [all | printer...]
Enables printing. Starts a spooling daemon for the printer. all
specifies that this command is performed on all locally attached
printers. printer indicates the command is performed on specific
printers. Specify printer as an atomic name. See printers.conf(4)
for information regarding naming conventions for atomic names.
stop [all | printer...]
Stops a spooling daemon after the current job is complete. Disables
printing at that time. all specifies that this command is performed
on all locally attached printers. printer indicates this command is
performed on specific printers. Specify printer as an atomic name.
See printers.conf(4) for information regarding naming conventions
for atomic names.
topq printer[request-ID...] [user ...]
Moves request-ID or print jobs belonging to user on printer to the
beginning of the print queue. Specify user as a user's login name.
Specify printer as an atomic name. See printers.conf(4) for infor‐

up [all | printer ...]
Turns the queue for printer on and enables printing on printer.
Deletes the message in the printer status file (inserted by down).
Use up to undo the effects of down. all specifies that this command
