Canon mx922 printer does not AirPrint
My Canon MX 922 printer no longer shows us as an AirPrint printer. I have tried WiFi, plugging it into an Airport Express and Wired Ethernet LAN. I can print to it from my Macs, but it never shows up as an AirPrint printer from iPhone or iPad. It used to. Maybe since upgrading to IOS 8 it has stopped. Not sure.
MacBook Air, OS X Mavericks (10.9), Yosemite
