Development of a Windows service to communicate with a JavaScript/PHP web application
Budget: $30 – $250 USD
I need a software developer specializing in C++ Development and web development with JavaScript and PHP. I need a windows service that can connect to a POS receipt printer and an existing POS web application. The POS printer connects via USB, and comes with an SDK written in C and C++.
When the user of the web POS records a transaction (Or registers a sale), the windows service should automatically retrieve the details of the transaction (Name of the items sold, their price, quantity, how much was paid, the change, the name of the cashier and the name of the customer if registered). The service should also indicate if the printer is connected, then this should be displayed on the web application which runs on a Web browser like Chrome, Edge or FireFox.
If you can design the JavaScript to work with the receipt printer’s SDK (Which has been written in C and C++). For online, you can design the windows service to check for the transactions to print in the online database. If a transaction has been printed out, the service should not print the details again unless, the transaction is reversed.
