AirPrint still not working after IOS 15.3.1 update

Hello Moocow01,

After reviewing your post, it seems like there is trouble using AirPrint from the iPhone. Let's get a little more information to help narrow this down.

Did AirPrint ever work with this printer and iPhone?

Are you able to AirPrint to other printers?

If you don't see your model listed, check with the manufacturer for more information.

AirPrint stopped working for me as well after updating to 15.3.1. It was working fine before that. I have a Brother printer set to static IP w/ WiFi enabled and also connected via wire. Running a UniFi Dream Machine Pro, UniFi 8-port switch, and U6-lite AP. I tried updating the printer’s firmware to latest version too and still no luck. AirPrint was working fine until the iOS update.

Same issue: works perfectly before 15.3.1 update, cannot connect after.
