Nah, it was a Brother printer, I replace it with a cheap HP printer. The Wireless on that one stopped working, I've just given up and my wife uses the cable to print. Well luckily the HP is still playing nice over a USB cable.
I remember this issue from a while back. Some update happened, and then wireless printing stopped working on some iOS devices. It happened to a colleague's macbook, and disabling IPv6 on the Brother printer fixed it for us. I can't remember where I found the initial advice, but here's someone else mentioning it: https://discussions.apple.com/thread/250584298
Any sufficiently large discussion of printers will beget a number of ad-hoc support sub-threads.
