If it makes you feel any better, I'm having the same problem with an Epson Stylus Photo 700. I recently emailed Epson about it and this is the reply that i received.

Thank you for taking the time to contact Epson. It is my pleasure to respond to your inquiry.
Currently, Epson does not offer driver for Mac OS X with the Stylus Photo 700. As of now, there is no release date for the drivers. Check the Epson web site @
WWW.EPSON.COM for future updates.
