cannon mp620 printer
My parents have this cannon mp620 wireless printer....It's been installed and working for awhile now....not sure how long. yesterday they printed from there laptop wirelessly and today they can't. They get error: printer not responding. This was the same thing that happened to there HP wireless printer. With that one I uninstalled and reinstalled a bunch of times to end up having the same error. Now the cannon is doing the same thing. What could be the root cause of this and how can I fix this?
