Thanks for your answer, but EPSON Scan does work in Windows 8. I have the GT-S50 which uses a one-button software called Event Manager. You can program different actions into Event Manager depending on what you select on the screen, like B&W Single-Side, Duplex, etc. and the destination folder. So all you have to do is put the document in the feeder, make your selection and press the scan button. Well, Event Manager doesn't work in Windows 8 and EPSON doesn't seem to have it, although I will check the link that you posted, just in case.
Yes, I went to the Epson Europe page, I was looking in the North American page. I found that Event Manager version 2.5 and up is Windows 8 compatible. It didn't list it for my model, but I downloaded it for the NX330 Multifunction and it works!
I have been using Epson RX-425 (ink jet with scanner).
No drivers or epson scan for Win 7 and 8.
I have successfully used driver & software (including Epson Scan) for Windows Vista - it does work on Windows 8 !
The file is: epson3130eu.exe.
I hope it helps as a scanner, RX-425 is still quite useful.
