Riti Printer: You're Not the Only Thing That's Coffee Powered

The Riti Printer solves the problem of costly ink cartridges, the difficulty to replace them, and finally gives you something to do with coffee and tea dregs. This clever printer is completely powered by the user moving the ink cartridge--packed with breakfast recyclables--by hand, from left to right until the paper has moved through the printer. This small printer is probably best for printing things like a letter to Aunt Trudy in Nebraska, not important business documents, but it is still an idea to be admired. Could be dangerous to use after six expressos, however.
