RITI Printer Uses Old Coffee Grounds as Ink

Fortunately, I don't use my printer nearly as much as I used to—but that doesn't mean I enjoy paying ridiculous prices for ink. Imagine if you could replace that pricey ink with old coffee grounds?

RITI Printer Uses Old Coffee Grounds as Ink

If the RITI coffee printer existed as a real-world product, you could do just that. The design calls for spent grounds to be poured into a cartridge and for the printing mechanism to be manually moved back and forth to create an image. I think the whole "manual labor" thing takes the eco-friendly concept a bit too far, but if old coffee could actually be used for ink I would be all for it. It would also infuse a delightful scent into your resume that would give you the edge on any job application. Plus you could lick your documents if you were ever really jonesing.
