Managing Spoolers, Queues, and Logical Printers
Managing Jobs in Queues and Spoolers
printers associated with the queue, but the queue will still receive jobs
from its associated logical printer or printers if they are enabled.
While you seldom need to pause a queue, you might want to pause a
queue to modify a job or jobs in the queue before they are scheduled to
physical printers. For example, you can resubmit the job to another
queue or give it a retention period. If you don't pause the queue, the
spooler might schedule the job before your command takes effect.
It is a good idea to pause a queue that contains jobs if you have to shut
down the spooler. Do the following:
1. Pause the queue.
2. Shut down the spooler.
3. Do whatever needs to be done while the spooler is shut down.
4. Restart the spooler.
5. Resume the queue.
If you do not pause the queue, HPDPS tries to schedule the jobs after you
restart the spooler, but will not be able to until the physical printers have
registered with the spooler. HPDPS generates notification messages
stating that jobs cannot be scheduled.
If you pause the queue, HPDPS does not try to schedule the jobs until
you resume the queue. HPDPS will not issue the notification messages
after you restart the spooler indicating that it cannot schedule the jobs.
You can also prevent the queue from sending jobs to a particular
physical printer in the event of problems with the physical printer. In
this case, disabling the physical printer is a better solution than pausing
the queue. This prevents the physical printer from accepting additional
jobs, but any jobs already scheduled will finish printing.
Also, if the queue sends jobs to more than one physical printer, disabling
the physical printer with the problem allows the other physical printers
to continue undisturbed. See “Disabling a Physical Printer” in Chapter
10 for further information.
Resuming a Paused Queue
Resuming a paused queue allows the spooler to schedule jobs in the
queue to physical printers. You can resume one or more queues with a
single command.
