Hello Brandon, Thank you for submitting this bug and reporting a problem with cups. You made this bug report some time ago and Ubuntu and cups have been updated since then.
Could you confirm that this is no longer a problem and that we can close the ticket? If it is still a problem, are you still interested in finding a solution to this bug? If you are, could you let us know and, in the current version, could you run the following (only once): apport-collect 1658822 and upload the updated logs and and any other logs that are relevant for this particular issue. Thank you again for helping make Ubuntu and cups better.

My other laptop running 14.04 prints flawlessly to the same printer. They are similar ASUS models. I did print from the new machine once, right after installing the drivers, but eventually I get a 'printer may not be connected' message, even if I delete and recreate the printer. The jobs just queue up, and the printer never leaves deep sleep mode. I don't think a signal is getting the the printer to wake it up. Of course, the CUPS version is different. The 14.04 machine (the one that is working) is running 1.7.2-0ubuntu1.7 and the 16.04 box is running 2.1.3. Sorry, but it's not with me, so I can't get much more specific that that. All updates have been applied, though, and I even tried the version in the experimental (proposed) repo. I've done my best to eliminate all other possible causes of the problem, such as... I'm using Brother print drivers downloaded from their site using the installer script (2.0.0-1). It currently pulls down version 1.1.2-1.i386 of the CUPS wrapper and lpr files automatically. I've also tried version 1.1.4-0.i386 of the CUPS wrapper that I kept from a previous download. The 1.1.4-0 driver is what works on the 14.04 machine. To eliminate potential network problems, I've changed many network settings. The printer is connected with a wire, not wifi. I have a static IP address on it, but I tried using DHCP just to see if that was an issue. Brother's best suggestion was to turn on IPv6, but that didn't solve the problem. I even changed the physical port on the switch, just to cover all the bases. I don't think it is a network problem at all, although I cannot always ping the printer from the new machine, whereas I can always reach it from the old machine.
