While the Arduino family of boards connect to your computer using a USB virtual serial port, the ATmega ones have an actual serial connection on-board.

After some research, it was determined that it would be relatively simple to have an Arduino convert incoming serial data into a parallel output to the printer.

Finding a more accessible client or writing my own, preferably in an accessible language like Python, that could drive the Arduino with serial commands.

Some microcontrollers like Arduino have very limited internal storage space, so an external EEPROM will be suitable for small amount of data storage or for extending the data storage capability of a ...
