We got all our parts, and spent a lot of time trying to reverse engineer LG Popo Mobile Printer until we finally realized that it was almost impossible for us to build a printer that works with ZINK paper at the time. So, after meetings with our TA and Professor, we decided to change our idea to utilize sensors and LEDs with LG Popo printer to make a printer that prints photos correspondingly to the environment and to display the obtained data on LED.
