_connectPrinter => (printer) => { //connect printer BLEPrinter.connectPrinter(printer.inner_mac_address).then( setCurrentPrinter, error => console.warn(error)) }

printTextTest = () => { currentPrinter && USBPrinter.printText("sample text\n"); }

printBillTest = () => { currentPrinter && USBPrinter.printBill("sample bill"); }

...

@marceloch2 @aasuparekh1 Same issue does anyone got the solution?

[marceloch2]

@Hasham24 @aasuparekh1 I'm using NetPrinter.printRawData(decodedReceipt), maybe not related but you have a typo. "prinRawData", so "prin" instead of "print"

I'm able to use this printRawData using a fork that I did, I can't remember right now what I did, but you can try just to see if works https://github.com/marceloch2/react-native-thermal-receipt-printer And RC version: "react-native": "0.73.6",
