I had nothing but problems with printing photos on my Mac. I used the latest Epson drivers. Even the older drivers from Epson from 10.5 were junk. I was about to give up. Even from Photoshop CS4, the output was awful. And believe me when I tell you, I went thru 30 sheets of 4x6 paper and 20$ worth of ink trying to figure which buttons to push and knobs to turn to get a good print. NO LUCK. The best I could to was just OK.
I went to help my niece with a Mac laptop problem and she printed a photo for me. The output from her similar printer was terrific. She was using 'GutenPrint' drivers.
I tried 'em.... the newest 5.2.5 rev and they are terrific. I can match prints to my calibrated monitor.
Clarity? Saturation? Shadow detail? All tops. And this is from the 100$ Epson printer....the R300.
Anyone else having Mac printing problems may want to try these drivers.
