Can't find LAN connected AirPrint printer
Hello - trying to use AirPrint on and iPhone 6S 12.0.1 and an iPhone 5SE using 12.0. I'm pretty sure this is new; that is, I'm pretty sure that this was working a week ago. Anyway, today neither iPhone could "see" the Brother HL-3170CDW that is connected to the Amplify via an Airport TimeCapsule in bridge mode. An AirPort capable printer should be "seen" by an iOS device connected to the same network, yes?
Take this with a grain-of-salt BUT my HP's all-in-one printers wi-fi is automatically disabled when connected to Ethernet. Perhaps something similar is going on with you???
