SHOCK??? hahahaa!! me too. .



Well let me tell you the description of the Coffe Printer.. .
It uses the Spent grounds for ink. .
This must be the answer to your problem. You can save money for expensive inks on your printer.
This one surfaces; printer that uses your own spent grounds as an ink source. Drop the grounds in, insert paper, and move the lever back and forth over the paper to make the image/text.
The RITI printer is an Eco-friendly printer based on the concept of a new ink system. We focused on the ink cartridge since it is one of the problems when using a printer: it's often difficult to replace, costly to refill, and can stain your hands if mishandled.

The RITI printer uses coffee or tea dregs. The user places the coffee or tea dregs into the ink case located on the top of the printer, then insert a piece of paper in the middle. Moving the ink case left and right will print your image, and as you draw on the paper, dregs in script on the paper just like ink.

Using coffee or tea dregs as ink saves the cost buying ink, the burden of wasted things, and users' work. Furthermore, since the user moves the ink case in order to make a print, the device doesn't need electricity. Of course, you can smell a whisper of coffee or tea incense from the paper printed by RITI. It cost's P7,413.80

Use:
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
