I have an HP Photosmart 5520 which keeps appearing offline to OSX so I have to reset the printing system and add it back in. Could the fact that my laptop's up time is 14 days now have anything to do with it (I found it starts to get buggy the longer it's on)
It's a Retina MacBook Pro 2014 version with OSX 10.11.6
