I just changed from winXP to win 7-64 and found Epson has no drivers for my stylus photo 870. After reading the above messages I decided to try "add a printer" from the win 7 menu. I turned on the printer, then the program went to the internet somewhere "to update the printer list." I chose the 870 from the list, then the system invisibly installed the driver and the printer works! Can't really say exactly what happened, but it was quick.
This was from an old thread on the forum,this user claims what i stated earlier should work.Give it a try!
