How to organize the printing of checks from the browser on the cash register through the google chrome extension?

Question

JavaScript

What is the best way to print checks from a browser? At this stage, I decided to make a chrome application, but when sending different things to serial, I stumble upon silence from the side of kkm (atol). Perhaps someone has an idea?
I would not want to freak out and write a separate application for the desktop.

Answer 1

There was an article on Habré where the guys solved this. The point was that they run Node locally. The browser connected to the localhost via a websocket and worked with the periphery in this way.

Answer 2

Run chrome in kiosk mode and then printing will take place without a confirmation window. And no third party extensions.

Answer 3
