AirPrint printer not available on iMac or any iOS devices
I have set up my Brother HL-L2370DW wireless printer using the AirPrint function. Routinely, ie. nearly always, the printer is not found when attempting to print from my iMac and iOS devices. It becomes available as a printer on these devices if I turn the device wifi off then back on. This occurred with my HP printer also. I have a xfinity XB7T router, the newest generation.
iMac 27″ 5K, macOS 11.3
