Expo React Native Thermal priner APP

I have an Expo React Native (Android) APP which is pulling orders from a third party API, I want to be able to connect a thermal printer through Bluetooth to the APP and have the following options;

- Check regularly for orders where the print status is set to false, and if so print two copies then change the status.
- Option to manually print from within the print details screen
- Option to select the printer to print to from the connected Bluetooth printers

I can supply the source code for working APP so far without the Bluetooth Thermal printer part, need to have the source code returned to me once done so I can finish the remaining bits from my end before generating the final APK file.
