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 inscript on the paper just like ink.
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
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.
*Licks paper* MMMMMM, delicious!
