Remove headers and footer from printed pages.

Hi guys, I have created a little "order" system for our company internal needs, and when I want to print the order, I use a special page, that has a jpg picture as a background and all items are positioned absolutely on the picture. This thing makes all the frames and lines look good. Now, when I print the page, I'd like to get rid of the "header" and "footer" that browser adds on the printed page. Does anybody have an idea how to do this? I know, that I can change these settings in IE manually, but I have no intention to go to every computer and change it, and even have no idea how to do that in NS. tia, Dezider.
