AirPrint iPad and iPhone to Canon mg7720 in iOS 12 only does photo paper
I can only print on 4 x 6 photo paper from iPad and iPhone to canon mg7720 in iOS 10 in the last 2 or 3 months. Previously this worked fine. What Advice do you have to print documents on 8.5 x 11? a Letter size print view pops up but immediately disappears and only photo selection is available
