I follow the Apple instructions to airprint but the iphone12 app says "No Printer Selected." There's nothing to select?! My Brother printer used to appear. How can I get it back?
It's in topic above
iPhone 12, iOS 15
Apple AirPrint works seamlessly when your Apple device is connected to the same network as your printer.
Avoid the mistake of assuming that your iPhone is connected to the same wireless network (just simply check).
Same with your printer.
It’s that easy!
