Hi,
After enabling AirPrint on remote UI of my LBP633C printer I can easily print from any iOS/iPadOS/MacOS device.
But after few days, when trying to print using AirPrint - the printer disappears.
Re-enabling AirPrint on remote UI solves the issue immediately w/o any other change at the network.
Looks like the printer's firmware has a bug with mDS/Bonjour...
The printer is connected via WiFi and has static IP.
I can always print using PRINT iOS application which is using the static IP.
Of course the firmware is up to date.
