Have you ever tried scanning in a picture of a US Dollar? ;-)

HOLY SHIT. I never knew about this. Makes me wonder though if someone decided to prevent the scanning of every single currency out there and the developers had to code in a shitload of recognition patterns into the scanners firmware.

http://en.wikipedia.org/wiki/Eurion suggests currency has some common features.

Works perfectly fine on Linux (scanning with SANE, editing with Gimp and printing with HPLIP).
