start prnting after a printer is turned on?

[SA]

Jack,

Thanks for this - it is really very useful!

> This is a similar issue that I have had with networked printers. If a printer is offline or unavailable the queue is set to "paused" by Cups and printing will not be restarted until manual intervention by the user. My solution is an ugly one that I got from another thread on this site. I run a cron job, like the script below, that automatically re-enables ALL Cups queues every minute:

At that point, you will be able to capture a print failure event somehow and run a script to handle the event on a one-time basis instead of running a cron job every minute to blindly re-enable the printers you want to print without any user intervention.
