I have a Brother HL-L8260CDW printer connected via USB to a machine running Linux Mint 18.3 Cinnamon.
The printer works fine -- however after a time period it becomes "unplugged".
In order to get it to work again I have to go to Printer Properties -> Policies and click "Enabled."
Any idea why this is happening and how I can stop the printer from being "Disabled" automatically?
I had previously used this printer on Linux Mint 17.2 MATE with no problems.
