I'm currently running tests on Windows 11 as an insider. The problem is that on all my devices running Windows 11 on test the Microsoft search for adding air printers doesn't find printers on the same network. Even if you add the manually by downloading the printer software Windows fails to communicate with the printer even though windows diagnostics knows its there. I have tried different air printers all with the same problem. Each computer and laptops I have individually wound them back to Windows 10 and on Windows 10 all devoices find all air printers and work correctly without any manual setup.
