Ok, I will assume it's 32-bit winxp.
Here's the link to their driver page:Epson Artisan 800 Drivers
Now looking at the choices available you need:
- epson config utility v3.7.0
- Scanner Driver and EPSON Scan Utility v3.44A
- Printer Driver v6.63
- Drivers and Utilities Combo Package - epson13282.exe
Which one did you have?
