Printing pages that contain javascript amended values?

I've created a page which is an awful lot like a spreadsheet. It thus has cells which are changed through javascript. The main problem is when I have to print. I find that the values that are changed are not on the printed version. Does anyone know how to solve this problem? Would using CSS 2 work?

Thanks.

javascript generated content is not printable.. I can't see how using CSS would change that.
Have you considered making your app a server side thing instead of client side? that way you could save a users work so they could resume working on it at a later date and you'd be able to print it as well.
