OSX 11.4 with bonjour.  Great printer, which was SO EASY to setup, and I could print from all my devices wirelessly.  

HOWEVER, after a few hours it goes offline.  Waking it up manually and then ADDing it as a printer again works...for a few hours, but it always goes offline after a few.  I tried a dedicated IP on the wireless network, but was no help.  It seems to disconnect (perhaps when it sleeps?) and then won't automatically reconnect.

I put it on a wire, and all is well with my mac which is also on the same wired network, however wireless devices understandably can't find it as thats a different network.

disappointed.

Is this happenning to everyone?
