Researchers are finding interesting things that coffee seeds can do apart from the energy caffeine induces on a sip-by-sip basis. Recent reports suggested that coffee grounds could be used as raw material to create biofuel and now a wiser individual has created a printer that uses coffee grounds for ink.

Korean designer Jeon Hwan Ju has created an eco-friendly RITI Coffee printer that actually uses nothing beyond coffee grounds, and every time you need to print a page you also get the added bonus of building up your biceps. How is that, you may ask? Well, the printer designed by Jeon works on mechanical power and hence you will just need to pour in the dregs and move the handle back and forth to get your printout.

This obviously means that you won’t rely on electricity for printouts and that sounds like an added bonus. So what if the pages smell like coffee? That only helps you wake up from your afternoon slumber at work. Right?

Just a prototype for now, the invention could well find a commercial version sometime in the future; or at least we hope so. [via GreenDaily]
