Photomyne is great for scanning of paper photos
If you haven't already discovered Photomyne I think you should try it. I think the result is better than with Google Scan.
I don't use my scanner in my printer anymore as it does not work properly with Win10. But I don't care - scanning with the phone is easier and the resulting photos are good enough for my purpose
Here's a photo of my son 25 years ago. Taken with an ordinary cheap compact camera. The scanned version looks better than the album photo - I really don't understand but it's great.
