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).
