A Sticky situation...
What would you do in the following situation?:
1. You need to print out a .aspx page.(A filled examination form..to be exact)
2. The Print button on the top of that page requires Internet Explorer(...and the page shows resistance to copying...by an ugly dialog box :P)
3. You do not have a printer.
4. The page will not be accessible from a public computer.
Sounds like a perfect storm of poor design choices. File a complaint or bug report.
Most of the screenshot plugins for Firefox/Chrome will save the whole page at once, they just grab image data from the browser's rendering backend. Or something like that.
Save the page as HTML on your hard disk... re-open it in your browser and use the browser's print page functions.
