This is very discouraging to read all these post with the same issues I am having... I have been a little weary of buying an HP printer for quite a few years now after the one I had was always giving me problems. I was pointed to this 7520 when I was looking at getting a new one and told how much better they have gotten over the years. I was a little skeptical but I went ahead and bout it in January.
I had it connected and have been able to print off and on and then out of no were it stops, (shows that it is not connected even though the printer is showing it is), Apps never worked (shows its updating then just cancels out). I was able to print, now nothing. It won’t even show that it’s connected even though both the comp and printer are showing they are and now HP utilities cant even find the printer.
I’m so frustrated right now it’s not even funny! I have the 7520 with the correct Firmware... I have installed and uninstalled I don’t know how many times now and it wont even find the printer on the network... GRRRR!!!
