There are few personal tech indignities that get me more riled up than the cost of printer ink, the control of the ink trade by the big printer companies, and the inability of most cartridges to be user-refillable. So I love this ol’ hack, from 2002, that’s resurfaced on the hack sites. It takes an Epson 760 printer and makes it into a continuous ink supply system by hacking each of the carts and attaching tubing that feeds ink to them. I assume folks have done similar hacks to other printer models.
