I finally finished this project. I had previously made a much smaller version with only a LCD screen, but no printer as they were not available at the time.
First I started out getting the thermal printer to work with an Arduino and a LCD screen.
Once I had this working, I wanted to make a more permanent version. About this time Adafruit started selling perma proto boards. These are great for soldering your project into and are very sturdy….
