I have been using my Canon MG7720 as an airprinter for a couple years (ever since purchase.) All of a sudden, it will not show up when I go to print from my iPad, iPhone, or Mac. I have restarted everything including turning off all of my items and printer and then restarting the router (which is Xfinity.) I then waited 5 minutes and plugged in the MG7720 printer. It found the network and I entered my password to connect just fine. I waited 5 minutes and started my Apple products one by one. None can “see” the MG7720. This is so strange since the printer connected just fine for years. Any suggestions?
