The command
lpc is used to display the status of the
print spooling system and control the availability. A print queue
relates to an individual printer. The spool deamon
relates to all printers.

|
- Displays
a short description of each command
specified in the argument list, or
- If
no argument is given, a list of the recognized commands
|
| status |
|
Display the status of daemons and queues
on the local machine. |
| topq |
- printer
and
- jobnumber
or
- user
name
|
Place the jobs in the order listed at the top of the printer
queue. |
| abort |
|
- Terminate
an active spooling daemon on the local host
immediately
- Disable
printing for the specified printers
|
| clean |
|
Remove any temporary files, data files, and control files
that cannot be printed from the specified printer queue(s)
on the local machine. |
| disable |
|
- Turn
the specified printer queues off
- This
prevents new printer jobs from being entered into
the queue by lpr
- Opposite
of enable
|
| down |
- all
- printer
name
- +
message
|
- Turn
the specified printer queue off
- Disable
printing
- Put
message in the printer status file. The message doesn't
need to be quoted.
- This
is normally used to take a printer down and let others
know why the printer is down and print the status
message
- Opposite
of up
|
| enable |
|
- Enable
spooling on the local queue for the listed
printers
- This
will allow new jobs in the spool queue
- Opposite
of disable
|
| up |
|
- Enable
everything
- Start
a new printer daemon
- Undoes
the effects of down
|
| start |
|
- Enable
printing
- Start
a spooling daemon for the listed printers.
|
| restart |
|
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.
Lpq will report that there is no daemon present when this
condition occurs. If the user is the super-user, try to
abort the current daemon first (i.e., kill and restart
a stuck daemon). |
| stop |
|
- Stop
a spooling daemon after the current job completes
- Disable
printing
|
| exit
or quit |
|
Exit from lpc |

The configuration
and controls for each printer are stored in /etc/printcap.
The spooling system accesses the printcap file every
time a print job is issued. Each entry is used to describe one
printer.

Example
printcap entries....
hp8500:\
:rm=hp8500:\
:rp=raw:\
:mx#0:\
:lf=/var/log/hp8500log:\
:sh:\
:sd=/usr/spool/lpd/hp8500:
The above entry represents...
- print
queue name hp8500 (Could be called whatever
you want)
- print
device rm=hp8500 (This is a network printer that
has an entry in the /etc/hosts file)
- printer
option rp=raw (Send data as is)
- limit
mx#0 (No limit)
- log
file lf=/var/log/hp8500log (One entry written to
log file for every print job)
- suppress
print header (banner) sh (no value represents
off or no)
- spool
directory sd=/usr/spool/lpd/hp8500 (directory where
actual spooled files reside until printed)
lp:\
:rm=hp8500:\
:rp=text:\
:mx#0:\
:lf=/var/log/hp8500log:\
:sh:\
:sd=/usr/spool/lpd/hp8500:
The
second entry is a print queue named lp.
It is the same as hp8500 except it sends the data as text
instead of raw.
