Printing on Thermal printer from Boot2Qt image

Oleg Romanenko

Hello,

I have chinese thermal printer Zj-58, Zj-80, and would like to be able to print on it using Boot2Qt image. Any references or manual on how to do it?

Hi,

How do you connect that printer to your device ?
What protocol does it use ?

Oleg Romanenko

It's connected by USB.
This is the printer: https://www.adafruit.com/product/597

I was able to control it from Python, using Adafruit library, and wondering if there is anything in Qt to do the same in Boot2Qt image?

SGaist

Do they provide a C or C++ library also for that device ?

Oleg Romanenko

They don't. I think I will try to use QSerial to send commands for the printer. I'm sorry, it was not really a Qt question at the end of the day.
Will post here, once I will find a working solution or develop a lib for Qt.

You might be able to translate the python library in something that is suitable in C/C++.
