So the deal is this. If in CS5, you have Printer Manages Color, and you go into the Epson driver, and you happen to have the Color Matching set for ColorSync, you’ll get the ugly grayed out UI I have below. I’m not sure why. If you switch Color Matching to Epson Color Controls, you get your driver options back.
IF you have Photoshop Manages Color set, well the Colorsync radio button Color Matching within the driver is automatically selected and grayed out. And the result is, you have an ugly driver whereby you can’t select items in the driver. I’m not sure why.
Its just another of those messes with driver/os/app’s. The behavior is different in Lightroom 3 FWIW. The 3880 is completely different! You can have Photoshop Manages Color and select anything in the driver except the options in Color Matching (its always set to ColorSync and grayed out).
