Hi , its my first printing after installing snow leopard , and I found in aperture print dialog , I used to go to printer setup and in there I had color management and could chose colorsync , its not there any more ! and it was the one that worked great for me .
Anybody had this problem ?, and how did you solve it
Did you update your printer drivers? I'm not familiar with Aperture but if you're using an Epson printer then read this article: http://macperformanceguide.com/SnowLeopard-Printing.html
I guess that Canon and HP also have new drivers for Snow Leopard.
