Monterey update completely screwed up wireless printing for my MacBook Air

I have a 2017 13-inch Macbook Air which was updated to Monterey from Catalina.

After the update I have been unable to resume normal printing.

I had a Samsung M2020W and an HP 107W. immediately after the update all the printers were viewed as offline, while at the same time a Windows 10 laptop on the same network works fine.

I tried deleting and reinstalling, resetting the printer settings on the mac, in short, everything that has been described on the internet.

I soon realised that the HP 107W is not supported by Monterey, neither is wireless setup of the Samsung as the relevant software is incompatible.

The samsung only works via USB, and the HP does not work at all...

As this is my work laptop and I need the be able to print, I went out and bought a Brother HL-1210W which is supposed to be compatible with Monterey.

This works on an on and off basis. I installad it and it seemed to work with a test print, but soon after that the printer seems to be offline while all other computers seem to work fine with it...

I have come to the end of my tether with Monterey and I will try to downgrade to Catalina, but any advice is welcome
