An "electronic stamp" built from an inkjet cartridge and a microcontroller, including some notes on reverse-hacking a modern inkjet cartridge. If lower resolution is acceptable, Parallax has a 96 DPI inkjet printer kit, complete with schematics and source code, and it seems like the critical thing is to hit the nozzles with 20-25v for 3 microseconds or so (probably less for the higher res cartridges and heads).

Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
