I am trying to print simple web pages using Vista and Internet Explorer.

All I get is the header and footer, the rest of the page is blank.

Something as changed because this used to wrok fine!

Any software changes recently since working last?

see if this helps
do you happen to have microsoft office installed? What office does is install a save to file printer. It sets itself as the default printer also for some reason.

To fix this go to control panel, click on printers, right click the correct printer and click set as default. That will fix that problem
