safari crashing

I am using BigSur 11.1, which should include the latest version of safari (Version 14.0.2 (16610.3.7.1.9)). I have a HP Pro 8630 printer. In the wireless settings on the printer, thee is a toggle switch to turn the wireless on and off. This is a touch screen to adjust all the settings on the printer. I turn the wireless setting on and off and the computer instantly finds the printer again. Of course, this option may not be there for your printer and then you may need to restart your printer to get the wireless settings to reset.

I'm having the same issue, though it's more like once or twice a day. I usually have an InfiniteWP tab open and I haven't noticed the issue with that tab closed. You don't happen to use InfiniteWP as well do you?

Are you sure that happens only when Safari is open? My IMac occasionally loses the printer for what seems to be no reason at all, and I have to then manually turn the wireless setting on the computer on and off and then the computer sees it again.
