If the details of the code are published, I would think it might be interesting if some hacker found out the serial number of a politician's printer and made use of that information.

Possible, but you'd have to reprogramme the printer's firmware. Depending on the model, this is certainly possible, but is likely completely impractical. An intimate knowledge of, at minimum, the character generation algorithm would be required, as well as the firmware's API.

Possible. Not impossible. Not bloody likely.
