IE7 and iWeb blog

I created a website and blog for our department using iWeb 09 and it looks great. It displays just like I designed it on IE7. However the problem comes in printing. When my users (who are all using IE7) go to print, then things go kablooie and instead of the 4 pages Safari would print, they get about 36 pages, all blank except for one line of text at the top.

I assume it's a CSS problem from what I've read so far, but I'm not sure where to start looking the CSS, and was wondering if anyone has had a similar problem and found the solution.

Thanks for any help, or just for taking the time to read this, anyway!
