I've looked at HP's support site for information regarding and HP Laserjet Enterprise M606, and downloaded a user manual. Still, I could not find the topic of printing failing over to another tray.
Our payroll department keeps one kind of regular form printing in Tray 3, and another form in Tray 2. When Tray 3 runs out of forms, Payroll doesn't want printing to continue from Tray 2.
I modified Use another tray, which is under Administration Manage Trays to disabled. Is that the correct way to prevent failover to another tray?
