This download contains several files that let you use Epson Stylus Photo printers with your Macintosh computer. The Stylus(EX) driver installs the core files needed to run the printer, and the driver will appear in the Chooser after installation. The Epson Monitor 2 utility lets you check on the status of your print jobs when background printing is turned on, and ColorSync 2.0 system files add profiles for the Epson Stylus Photo printers and Apple monitors.
