Reminds me of Doom on a printer: http://www.contextis.com/resources/blog/hacking-canon-pixma-...

Submitted Engadget article rather than original forum thread because the thread has a low signal-to-noise ratio.

Did not retain title of Engadget article because it's so clickbaity.

Neat!

Yes, but whenever I see these things, I'm always in a bit of a quandary over them - the technical challenge element is obviously impressive, but the flipside is that there's probably nothing worthwhile that can be done with it. I've done the same myself - I spent days resurrecting a Zenith Minisport (including getting round the BIOS lock), but at a time when it was of no functional use at all. There must be something in our psyche that makes us perform such acts of folly!
