Re: [rp-ml] retrofit desktop printers

The RepRap project is looking at using the HP 51604A inkjet cartridge,
which is cheap and easy to interface. There's an excellent book on
it: Inkjet Applications by Matt Gilliland -

It's very easy to drive from any microcontroller - all the extra it
needs is an open-collector transistor array to shift voltages. We'll
probably use the Arduino microcontroller, which, again, is simple to
program (just type C in a window and hit the download button...)

All the RepRap driver software is open-source, of course; it's still
under development, but you can download it now. It's Java, so it's
completely platform independent. It is geared to the RepRap hardware
architecture, but it's pretty modular. Take what you need for free!

Best wishes
