The idea of software in a printer preventing you from printing counterfeit currency is ridiculous. These things (and similar nonsense in Photoshop et al) have only served to annoy graphic designers.
The only thing "protecting" real money is the many embedded, hard to replicate patterns and markers.
Of course, you can't put the genie back in the bottle with how guns work. You can't write software that will prevent anyone from printing gun parts, as if there was a way for the software to tell intentions from abstract 3D shapes.
- Turing_Machine 14y agoRight. Prohibiting 3D printers from making shapes with through-holes (i.e., a barrel) would be somewhat...limiting.

It is embedded in certain graphics program and in (computer-driven) printer/copiers for office use. Not sure about printer drivers, but probably just as well. The tech behind it is quite simple, actually: http://en.wikipedia.org/wiki/EURion_constellation http://en.wikipedia.org/wiki/EURion_constellation However, I can't imagine any similar solution working for 3D print. When one tries to copy bank notes, the `EURion constellation' is there, included by the issuer. However, when trying to print third-party designed 3D item, if the designer did not bother with including any protective markings, those simply won't be there.
