Discuss the commands used to manage CUPS queues.
What will be an ideal response?
In addition to controlling single jobs in a queue, you can also control the queue itself:
* Disable printing on a queue while jobs can still be sent to it by entering cupsdisable destination.
Queues that are disabled still accept jobs for printing but won't actually print any files until they are enabled again. Disabling a print queue is useful if a printer malfunctions and you need time to fix the problem.
* Start printing again on a queue that is disabled by entering cupsenable destination.
If there are any queued print jobs, they are printed after the printer is enabled.
* Stop accepting print jobs on a queue by entering /usr/sbin/reject destination.
With the /usr/sbin/reject command, the printer finishes the print jobs in the queue but rejects any new print jobs. This command is useful for times when you need to perform maintenance on a printer and the printer will not be available for a significant period of time.
* Accept print jobs again on a queue that rejected them by entering /usr/sbin/accept destination.
By using this command, you can reset the print queue to begin accepting new print jobs. If the queue is also disabled, actual printing starts only after enabling the queue again.
