I have a HP Envy 4520 that is under multi month old. It props up disconnected. I have put in new drivers on numerous occasions, erased and set up remote system on various occasions, and the main way I can settle is to kill and back on. This is extremely frusturating. I had a HP printer beforehand and never had these issues.
