OK, I don't have a solution that is very helpful but here is what I did for a friends pc. He had bought a new HP 4520 printer it would install on his Windows 10 but would not print. It would scan but not print. I know from past experience that this is normally a problem with HP's install/uninstall routine and once upon a time (In the XP world) they actually made a tool to do a complete "uninstall" of HP printers on the computer to include the registry files. It's too bad they haven't produced one for today's world of Windows 10 and plug and play.
Anyhow, I took my friends printer to my house, connected it to my network and my Windows 10 box found the printer on the network, installed the correct drivers, and I could print and scan anything and everything without an issue. So I knew the problem was in his workstation somewhere. I found several tools from HP but none of them resolved the issue.
I started looking at Windows updates hoping to see when the last update was and maybe I could go back to a previous update to see if it worked. That's when I noticed that none of the Windows updates have been installing and they all had failed for one reason or another. So at that point, I took his computer to my house, backed up his data, and reinstalled the Windows 10 OS. Once I did that, it found the printer, installed the correct driver and now I can print and scan to his new printer. And all updates have been completed and are working again.
So, with all this being said, I would run the sfc scan as someone else suggested, if that doesn't resolve or find any issues, then my thinking is, you could reinstall the OS and be done in an hour or two OR you could continue to hunt for an answer...
Anyway, something to think about. Keep us posted.
