Printer hangs up on a job

Cancels all submitted jobs on target printer

5. Restart printer

Check that jobs are printing

Clearing Boelter Lab print queues daily

1. cancel -a `lpstat -t | grep disabled | awk '{print $2}'`

This will list all printers that are currently disabled, and cancel queued jobs on those printers

2. /usr/bin/enable `lpstat -t | grep disabled | awk '{print $2}'`

This will re-enable the stopped print queues

3. lpstat -t | grep disabled | awk '{print $2}'

This checks to see that all printers are re-enabled. Should return nothing.

Remove printers from client computer

1. lpadmin -x `lpstat -a | awk '{printf $1 " "}'`

Lists all printers on client, sorts the printer names into a string, then issues lpadmin -x (removal) command to each printer. Command only deletes a printer at a time right now.
