Caution:
The installation programs for the EPSON Stylus Photo EX and EPSON
Stylus Photo 700 install the creative software before they prompt you to
install the printer driver software. Be sure to cancel the printer driver
software installation whenever you see the screen shown on the previous
page. If you don't, you'll install the old printer driver over the USB printer
driver.
2 Follow the instructions on screen to finish installing your creative
software or view your printer's electronic manual. See your printer's
setup documentation for details.
