How to print checks on the fiscal registrar ATOL 30F?

Question

Google Chrome

Hello.
There is a fiscal registrar ATOL 30F on which you need to print receipts from our CRM system. To do this, as I understand it, you need an extension for Google Chrome. I found 2 solutions:

1. native app
   
2. use https://developer.chrome.com/apps/usb
   

Question 1: What is the best option?
Question 2: What commands should be sent to the fiscal registrar in order for it to print a check?

Answer 1

The path you have chosen is thorny and difficult.
You form a page (write your extension) on (in) which (th) js on the client
machine communicates with the usb port (in fact, there is a com port protocol).
check registration process is to generate a bunch of low-level
commands (byte sequences), they cannot be sent to the whole check at once, it is required to
implement an automaton, if the previous command is successful, we do it further, otherwise we
roll back, etc.
After working out the algorithm, you will need to send the result to the server.
Alternatives - kkmserver.ru, a program from Bitrix, others are already ready.

Answer 2

DTO of the 10.x branch already knows how to work as an http (json) server. Branches 8 and 9 are already marked as dead and will not be developed.
Well, further - docks and examples: integration.atol.ru
Naturally, for immersion, it would be nice to study 54-FZ, forum.atol.ru where some people complain about jambs and share advice
