Jeon Hwan Ju's RITI printer concept is a caffeine addicts dream come true, using the leftover grounds of your last cup of coffee or tea to provide the "ink" in his printer design. We'd never, ever run out of ink in our home office, that's for sure. We hope to see a working prototype...maybe with invisible ink "white tea" cartridges or multi-colour cartridges fueled by different drinks!

Part of Core77's Greener Gadget competition, instructions are pretty simple:
1. Insert a paper in the middle of the printer
2. Put the coffee or tea dregs into the ink case on the top of the printer
3. Move the ink case left and right as you draw on a paper
4. When the print finishes, pull out the paper from the printer and wash the ink case

Local Starbucks could give Kinko's a run for their money!
