ESC/POS Printer Library

A Library to control an ESC printer by an ESP32 via Bluetooth BLE

At the moment I don't have an Arduino with Bluetooth BLE, but it could easily be made compatible in the future.

Requirements

An ESP32 board with Bluetooth BLE and an ESC Bluetooth BLE thermal printer, knowing the UUID of the service and the characteristic.

Tested

• Chinese ESC/POS printer called "BlueTooth Printer" & ESP32-S2 super mini, ESP32-C3

How convert image

Using the image2cpp project to generate the byte array

https://javl.github.io/image2cpp/

We upload the image and change the configuration that appears in step 2

In step 4 we select plain bytes and press the Generate Code button

we copy only the generated array and add it to our .ino in the logo array

How to use the library

It is available in the Arduino library manager or you can download the zip to the local /Arduino/libraries path of your IDE, once installed you can see the example in the menu or open it from the examples folder.
