A special problem

[admin]

I have a subscription web site that provides access to health care evaluation questionnaires. Those using the service enter data and can view progress reports. They can also print the reports. The site uses CSS to present printer friendly versions. However, I have numerous requests to eliminate the URL that is printed at the bottom of each page (automatically shows up whenever you print a copy of a web page). The users want to be able to submit these printed reports to insurance companies, but don't want the URL of the page included. Is there any way to block this? I would prefer to avoid creating PDF versions. The reports are dynamic and contain database content. Users are required to have javascript enabled and to be using IE 5.0 or later because of various tools. Thanks for any ideas.
