Assume you can only print web pages in black and white with colour photos, make it look as nice as you can like that. - your best bet is to really let the style fall away (you know when you add stuff to your reading list and it presents itself more basically... that is ideally what you want to do for print)
So long as your markup is semantic items should render in an understandable way... remeber that print is a totally different media to screen, make your print CSS reflect that.
