I wonder if someone would be able to shed some light on this problem. I have a Canon MP780 AIO which used to print good photos from my XP box, I have recently hooked it up to my Mac and I'm very disappointed with the quality of the prints from the Mac. The prints now seems washed out and dull, I have tried cleaning and alining the print heads with no luck. Doing some reading I think it might be something to do with the colorsync but I cant find any adjustment for that in the printer settings. Thank you in advance for any help.
