This script prints to a printer using the serial port of a Raspberry Pi, and plays a sound when printing.

1. Download the files from GitHub by clicking on the green "Code" button, and "Download ZIP"
2. Extract the ZIP, and copy start-printing, printer.service and printer.config to the home folder on your Pi*
3. In your terminal, run sudo cp printer.service /etc/systemd/printer.service

(*) The home folder can be accessed by running cd ~. On a default Pi install, it will probably be in /home/pi.

Open the printer.config file in a text editor. The file contains options, in the format option name: option value.

Change the text-path and sound-path options to point at your files. You can use ~ to refer to the home folder, e.g. ~/mysounds/sound.wav.

Change the baud rate to match the rate of your printer.

Simply open your Terminal, go to your home folder (cd ~) and run ./start-printing.

• The text file should be a plain .txt
• The printer will print one line of the text file at a time. So format it so that each paragraph is entirely on one line.
• Make sure the sound file is a valid WAV file. You can export it as WAV for example in Audacity (File > Export > Export as WAV).
