I started to have issues with AirPrint (Apple devices) over Turris Omnia wifi. I just wanted to ask, whether someone observers similar problems. For example because of some update of turris-firewall-rules. It has been working for months. I have not updated Apple devices recently. It is a printer Samsung M288x. I doubt that there is some firmware autoupdate. It still works over direct wifi connection (when the printer is a hotspot). I have problem to add the printer and when added, it seems offline. I could help me to know whether it is only my settings or already reported problem.
AirPrint works fine on my end. My configuration is following
- Turris OS 4.0.5
- Brother DCP-J105
- macOS 10.13
- iOS 13.3
I would recommend you to focus on the printer at this point. Little reset never killed nobody.
