My HP ENVY 4520 ALL-IN-ONE printer stopped working. I have been using it for several months wireless.
I've tried to reinstall the printer with the disc and also from the HP web site. I uninstalled and reinstalled each time. I first tried installing wireless again and after about 5 hours of trouble shooting and uninstalling and reinstalling I gave up and decided to use the USB cable. Same situation nothing after several hours of frustration. Each time the test sheets print but when I try to print a document...NOTHING!
