When doing a print style sheet, do you basically want to link to the page where there really IS NO stylesheet, that way there is no presentation? Do you want to change the fonts to certain attributes, like em or points? I know there is talk that Points should only be used for screen, I think. And what exactly is SCREEN used for?

I am looking at adaptivepath's website and trying to get a feel for their use of certain stylesheets

Thanks
