Digital BW, The Print

Greetings:

I have just switched over to CS3 and the new print dialog box that is 
supposedly color managed. I just sent a file to the printer with PS 
handling the color, relative colormetric, black point compensation and 
an epson profile loaded and the printer color management turned off as 
usual.

The weird behavior is that when I picked the color printing profile, 
the preview box turned the white background of my image pale blue. But 
when I got the print out of my R2400, the background was white just as 
it should have been.

Can someone give me some guidance as to what is going on with this new 
print dialog box preview pane and why I might be seeing this behavior.

Thanks in advance!
