I have my DVR set up for Gmail and tbf it was flawless until I turned off the alerts when covid happened. I tried it a couple of years ago and iirc it was a Gmail issue/update that stopped working.
HP laser jet at home and a Brother duplex thing at work, both rarely used to print, just occasionally scan.
Had to roll back the software on the HP because the fuckers updated it one night and it binned off the amazon toners.
