Python3 port of the original Adafruit Python-Thermal-Printer library.
Install Raspbian Buster and Wire the printer according to this. I powered the printer with the GPIO pins as well.
Run a test to see if the printer is working by punching in these commands into the terminal.
stty -F /dev/serial0 19200 echo -e "This is a test.\\n\\n\\n" > /dev/serial0
Update the system and install prequisities.
sudo apt-get update sudo apt-get install git cups wiringpi build-essential libcups2-dev libcupsimage2-dev python-serial python-pil python-unidecode
Install the printer driver. Don't worry about the warnings that g++ gives.
git clone https://github.com/adafruit/zj-58 cd zj-58 make sudo ./install
Make the printer the default printer. This is useful if you are going to be doing other things with it.
sudo lpadmin -p ZJ-58 -E -v serial:/dev/serial0?baud=19200 -m zjiang/ZJ-58.ppd sudo lpoptions -d ZJ-58
Restart the system. Clone this repository and try to run printertest.py.
git clone https://github.com/galacticfan/Python-Thermal-Printer/ cd Python-Thermal-Printer python3 printertest.py
Let me know if you have any issues.
