Epson Printer Drivers 2.2 for Mac OS X 10.6.1
Apple has released a driver update that “includes the latest Epson printing and scanning software for Snow Leopard.” More information on supported Epson printers is available on Apple’s Web site. The update is available via Software Update and the Apple Support Downloads page. (Free, 546 MB)
I have an Epson Stylus Photo R800, and since going to snow leopard the prints are all at low resolution . A pale grey. Nothing has changed with V 2.2. Also the supplied print Utility does not work. I have gone back to Epson's Leopard driver and get good prints,the print utility works, but slow printing response
I used this solution for the R1800 as well. I switch between Leopard and Snow Leopard with Carbon Copy Cloner so that I have the best of both worlds without the need to buy a new printer.
