I remember a story from years ago in the Nashua newspaper. A customer at the Lechmere store was printing fake auto inspection stickers on the color printers. Someone called the police and they arrested or ticketed him. This was back when a color printer was still an expensive novelty.
I also remember having some fun back in those days with early laser printers and FAX machines. You could make some really convincing fake documents and FAX them to your friends. Almost lost a few friends that way.
