Yes you can turn any scanner/printer combo into a copy machine using software, and you don't even have to pay for it...

A free program called (appropriately enough) Photocopier works with XP, Vista and even older versions of windows like NT and Windows 98. Simply set the number of copies and the lightness level, click the Copy button and, well, IT MAKES COPIES!!! it just works.
