I have an HP 8620 all-in-one wireless printer, which has worked like a champ for months under Windows 8.1 and Linux. I recently upgraded to Windows 10. My wife is still on Windows 8.1, and she is seeing this problem as well. All computers can still print to the printer.
However, both the Win 8.1 computer and the Win 10 computer have started showing messages about "Unable to scan computer - printer disconnected." These message show up periodically on both computers, and are rather annoying.
One post I found suggested it had to do with the printer going into some sort of power saving mode. That doesn't appear to be the case, as the printer was on, and able to accept print jobs, and I was still seeing this message pop up.
I've tried updating the drivers from HP, no noticeable change.
How do I clear whatever status is making the computer think this feature is no longer working, or at least shut up the warning about it?
