Managing Spoolers, Queues, and Logical Printers
Performing Other Spooler-Related Tasks
In this example, only one job has been assigned to a physical printer.
Several jobs are pending,meaning that they have not been scheduled,
and several jobs are held. You will use this type of information about
the jobs to determine the cause of the backlog and to perform the
appropriate tasks to address the backlogged condition.
Determining the Cause of the Queue Backlog
After you have determined the severity of the backlog and the types of
the jobs in the backlogged queue, check that the backlog is not caused by
one of the following conditions:
• Check for a paused queue.
A paused queue still accepts jobs but cannot send jobs to physical
printers. Use the procedure in “Querying for the Status of a Queue”
earlier to determine if the queue has been paused.
• Check for a physical printer that is not enabled or that is paused.
A physical printer that is not enabled or that is paused cannot receive
jobs from its associated queue. Use the procedure in “Querying for
Ready Physical Printers Associated with the Queue” earlier to
determine if the physical printer or printers associated with the
queue are enabled.
• Check for a physical printer that needs attention.
A physical printer that needs attention represents a printer device
that requires intervention, such as for a paper jam. Depending on
who created the physical printer and the notification profile for the
printer, you might not have received a notification message for a
printer problem. To determine whether the physical printer needs
attention, follow the procedure in “Querying for the State of a
Physical Printer” in Chapter 10.
If none of these conditions are causing the queue backlog, the cause is
related to the numbers and types of jobs in the queue, as discussed next.
Managing Job-Related Queue Backlogs
The following describes actions you can take for queue backlogs that are
caused by the numbers, states, or sizes of jobs.
• Do nothing to alleviate the backlog, but continue to monitor the
backlogged queue. If the queue backlog is minor, you might want to
wait and see if the queue becomes less backlogged over time as
