And have you contacted Epson about the problems with their driver?
Have you checked for updated drivers that might solve the driver problem?
And please make sure that you installed all the Photoshop updates.
I've done all of the above. All was well before I installed CS5.
My printer driver, Mac, CS5 should be compatible. I can print
with 'Photoshop Manages Colors' but not 'Printer Manages Colors'.
That still sounds like it's a driver problem. We'll see if we can reproduce it.
