I can’t wait until this bad boy comes out. I’m getting my hands on one of these immediately. The thought of using old coffee and tea grinds to print my next paper gives a whole new meaning to the idea of coffee stains on your homework.
The RITI printer was invented by Korean Joen Hwan Ju, and has not yet made it to market, but word is now exploding about it. Here’s what you do: Drink a cup of coffee (not instant) and put the grinds into the ink cartridge on the top. (Drinking the coffee not required for printing.) Add some water. Move the cartridge back and forth with your hand, and watch as your document gets burned in very precisely-patterned coffee stains into a readable document with words on it. Take the cartridge out and wash it. You’re done.
You can also use tea schmutz. After an English breakfast, take your teabag, rip it open, pour the contents into the ink cartridge and do the same thing.
Advantages: Leftover coffee and tea is generally a bit cheaper than a $50 ink cartridge. No electricity means you get some forearm workout and save power. Finally, you paper smells like coffee and/or tea. Just make sure that whatever color fluid you’re using doesn’t smell too bad.
Disadvantages: It’s slow, so if you have to print up thousands of flyers, don’t use this unless you’ve got forearms of steel and about 3 weeks of free time to do nothing but move tea dregs back and forth.
