The first place to always check for drivers is the vendor, and in this case Epson.
I did the "leg work" for you. HERE
is the Epson Win 7 downloads for this mode.
I commend you for checking BEFORE moving to Win 7 as a lot of people will do something and then find out something isn't compatible, but next time do your own "leg work" and if you need a driver or checking compatibility for something remember to first check the vendor.
