I have not been able to print text to the Phomemo printer using standard ESC/POS print commands (if your printer does work with these commands, you should use the library here). To work around this, this library allows printing of text as a raster bit image. It also allows for actual image files to be printed directly.
This currently only allows connection to the printer via bluetooth; various methods to connect to the Phomemo printer and print images are excellently described here if bluetooth does not suit your needs.
Tools were tested on a Phomemo M02 Pro printer.
- python3
- bluetooth interrogation tools (e.g. via the
bluezpackage)
sudo python3 setup.py install
This will create a CLI called phomemo_printer on your PATH.
Alternatively, install via pip:
python3 -m pip install phomemo_printer
The printer is connected to over bluetooth. To connect, the bluetooth address and channel must be determined.
The Debian package bluez provides the utilities needed to scan for and connect to the printer via bluetooth.
- Find the printer's bluetooth address
The printer should be powered on and not connected to any computer or app.
$ hcitool scan

00:AA:13:41:11:A5 M02 Pro
The bluetooth address should be in the format xx:xx:xx:xx:xx:xx. If more than one bluetooth device is discovered, look for one with the name of your printer.
- Determine which channel to connect to the device on
