Xerox scanners/photocopiers randomly alter numbers...
I've read about this so much, I wonder if B/W printers have anything similar? Is there a secret yellow cartridge somewhere in my printer that I don't know about?

Modern printers refuse to print/copy money anyway, right? At least ours did when we went to print some money for a themed Christmas party.
