You're looking at a fairly old printer there and there are no drivers
for Windows 7. If you still want/need to use the printer since it works under XP I would suggest you stick with XP until you can replace the printer.
Your other choice is to "try" the procedures in the link below with a Windows 98 CD If you have one). Under Windows 7, choose Windows 98 compatibility mode on the 98 CD and try the procedures in the link below. Make sure the printer is hooked up to Windows 7. I'm not sure this is going to work but its worth a shot. Epson America, Inc. - Epson EPL-8000, FAQ - Technical Support Edit
- OK, playing around with my 98 CD, try this for drivers if the above doesn't work (probably won't)...
Again, If you have a Win 98 CD, pop it in. Now, with the printer installed, once it asks for drivers search the CD for the driver
by navigating to CD Drive:\drivers\printers\epson, from there look for your printer and try installing the drivers. You may have to do Win 98 compatibility mode.
Again, I'm not sure this is going to work so...
