I'm a new Mac user, having replaced a Windows machine. I've just tried printing some photos from my iMac (with latest OS X fixes) but it comes out very dark on the Epson 750. Is there an - ideally - easy way to get the printout to match what I see on the screen? Is there a place I can read up on this? I did try going to the Epson downloads page but it didn't even list the Photo 750 among Mac drivers, although it did imply that my OS X system might have later drivers than the Epson downloads page, which seemed very strange.
