Note: I have nothing to do with Epson or the other company and did not get any reward for this post. I edited this post in 2019 to note Windows 10 and fix the links, and in 2020 to mention the new scanner.
I have an old Epson scanner (Perfection 1650) that I have used for ages whenever I needed to “reverse print” a document. On getting a newer, bigger SSD hard drive for my PC I reinstalled Windows 7. Evidently previously I was on x86, because now that I’ve installed x64, my scanner would no longer work!
