Inventors of gadgets do not know any limits. This can be proved by the printer which doesn’t print with ink or powder, but with … coffee!
It turns out that coffee is not only an invigorating drink, but can also be used as an ink for printing on paper by a special printer.
Coffee grounds are used instead of the usual ink in a new gadget-printer RITI, developed by Joen Hwan Ju. Yes, coffee grounds are suitable not only for divination but also for printing. Now there is no need to dispose the remains of morning coffee, but … to tuck your printer!
The principle of this gadget is as follows: the filter with coffee is removed from the coffee maker, and is placed inside the cartridge of the printer with a small amount of water.
During the printing cartridge is moved, as usual, from side to side, leaving the print on paper.
It remains a mystery how long a print will retain its properties. This is the most environmentally friendly way to print; now you can drink coffee without any waste.
