Basic Javascript + Websockets over MQTT Web App

I am looking for a talented developer to build a basic one page web app. This one page should consist of a form which on submission, sends data over websockets to an MQTT thermal receipt printer that then prints it out.

However to make this project a lot easier, I have attached Javascript library specifically built for this purpose and better still, there are lots of examples of code. One particular example is called "[login to view URL]" and when I loaded this into my browser, entered the local IP address of my MQTT printer in the address field and pressed Print, it successfully printed out the example receipt.

Your task is to implement changes to "[login to view URL]" so it can be uploaded to a web server and print to the same printer. I believe this will require a message broker that supports websockets so have installed and configured the EMQ message broker. [login to view URL]

- The freelancer should have knowledge of MQTT, Websockets, Javascript and of obviously some basic HTML too.

- The freelancer will be given access to the EMQ Dashboard.

- The freelancer can use his own webserver or I will provide one with FTP access to test his code modifications.

- The freelancer should deliver a working solution in 48 hours of being awarded.

Please note this is a proof of concept of project.
