Add autoprint POS printing functionality to existing React Native Application

We have an Expo React Native application which runs on iOS and Android. We need to add support for auto printing receipts (this means the receipt should print automatically without any confirmation prompt or input from the user) from the application to the following printers: Epson, Star Micronics TSP. The printing should work via Bluetooth and USB connection. This cannot be done through Expo directly - the app needs to be ejected from Expo to React Native, and a suitable NPM package can be used to connect to the printers. The app has all the code necessary to run already - all we need is to add the printing support.

As part of the deliverable, we need to be able to test the successful printing on both Epson and Star Micronics TSP printers via Bluetooth and USB.
