Unfortunately, updating to 10.6.3 did not correct the problem with V4 ICC profiles for me…. Version 4 ICC profiles still print with a gray border around the image. My solution, as with others, has been to remake my profiles as Version 2.
Wish there was better news…
Edit April 1,2010:
Today (4 months later) Apple replied to my bug filing, and admitted it’s a bug in their code. The bug tracking number is Bug ID# 7515184.

And Photoshop CS5 doesn’t fix it either, but now at least the preview in the print dialog shows it.

And Apple’s new Epson Printer drives released today don’t fix it either. At this point, it’s been a known bug for almost 5 months, and no one seems to care.
