Industrial designers Hoyoung Lee, Doyoung Kim, and Hongku Kim designed the Road Printer concept, a solar powered printed that collects solar power through its onboard solar panels. It has the ability to print signs like U Turn, Bus, Arrow Signs, Stop Signs, and more with just a touch of a button, thus it lessens the task of printing road signs that are currently done by humans. The printer have a pre-programmed designs in the memory where users will have to choose for the Road Printer to jet-spray onto the surface. The menu buttons are strong enough to withstand the users fingers as they push for choices.
