Administrating Printers As an administrator for your printers, you have had to install, set up, and test them. Users can still submit jobs, which will wait in the queue until the printer is started or the queue is cleared. An enabled queue allows jobs to be submitted. A printer can be started for a disabled queue, in which case it will continue to print jobs in the queue until the queue is empty. Most of the commands take a printer-name argument to tell on which printer to operate.
Users can still submit jobs if the queue is enabled.
Occasionally, the files that make up a job are not properly removed by LPD , particularly if there have been errors during printing or a lot of administrative activity. This command finds files that do not belong in the spooling directory and removes them. If the printer is running, it will continue to print any jobs remaining in the queue. Other users will not be able to submit jobs until you complete your testing and re-enable the queue with the enable command. Equivalent to disable followed by stop .
