What printer driver I need to install? I don't have an EPSON printer, but I have a V370 scanner.
In some cases you have to install a driver, in other cases you don't. However, this is clearly specified in the manual for your printer. If you don't have the manual or the CD, then I advise checking the Support page for Epson products. Input the product model of your printer and then download the manual to see what needs to be installed. I am pretty sure the printer/scanner requires FAX features or else it won't work.
