• Thermal printer

Firstly, we followed the instructions on Notion to test the thermal printer. However, when we tried to print uploaded images, they didn't come out clearly. Despite trying various file sizes, formats, and adjusting image transparency, we couldn't get a clear image on paper. We reached out to Zhenfang and Daragh, who helped us change the charger from 5v to 9v, and then to 12v. With their assistance, we were able to overcome the problem and develop several receipt designs, trying out different layouts, font types, and text sizes. It was an interesting process, and we eventually found a layout that worked well with the images.
