Matrix Thermal Printer

Print your incoming Matrix messages using a thermal printer

Getting started

Hardware requirement

ESP32

This project rely on a ESP32-s3. For the sake of simplicity I used the most powerful one available: ESP32 N16R8

The network is assured by a W5500 chip

Schematics:

Thermal printer

You will need a Thermal printer that support the Epson's ESC/POS protocol.

I made this project using this model: UNYKACH UK56007 but other model will work too.

You should define a proper IP address for the thermal printer. It must be on the same network as the ESP32. ``

Development setup

Note: This project is based on esp-hal

• Install Rust using rustup: https://rust-lang.org/tools/install/

• Follow the official Espressif instructions to install the toolchain and tooling on your computer

• Add yourself to the dialout group (to communicate easily with your ESP32):

sudo adduser $USER dialout

• Clone this project:

git clone https://gitea.communiquons.org/pierre/MatrixThermalPrinter
cd MatrixThermalPrinter

• Build a release version of this project:

cd MatrixThermalPrinter
cargo build --release

• Deploy this project to an ESP32:

cargo run --release

Project configuration roadmap

• Setup Matrix and wanted bridgets
• Setup MatrixGW and connect it to matrix
• Connect and configure your thermal printer
• Create an API token on MatrixGW for the printer
• Access http://ESP_IP/ (username: admin / password: admin) to configure the ESP
