Introduction¶

CircuitPython module for control of various small serial thermal printers.

Dependencies¶

This driver depends on:

Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example¶

See examples/simpletest.py for a demo of basic printer usage.

API Reference¶

adafruit_thermal_printer.get_printer_class(version)[source]¶: Retrieve the class to construct for an instance of the specified thermal printer version. Pass in the printer firmware version as a numeric value like 2.68, 2.64, etc. You can get this value by holding the button on the printer as it powers on and a test page is printed–look at the bottom of the test page for the version number.
