I want to make an application without interaction that only accepts parameters allowing to print labels on the LW-600P device, now I can scan the device and it is connected, but when it prints, nothing happens, I use this https://github .com/januslo/react-native-bluetooth-escpos-printer
ive tried this code :
`import React from 'react';
import { Button, StyleSheet, Text, View } from 'react-native';
import { BluetoothEscposPrinter, BluetoothTscPrinter } from 'react-native-bluetooth-escpos-printer';
import { hsdLogo } from './dummy-logo';
let options = {
width: 12,
height: 30,
gap: 0,
direction: BluetoothTscPrinter.DIRECTION.FORWARD,
reference: [0, 0],
tear: BluetoothTscPrinter.TEAR.ON,
sound: 0,
text: [{
text: 'Ioooo',
x: 20,
y: 0,
fonttype: BluetoothTscPrinter.FONTTYPE.SIMPLIFIED_CHINESE,
rotation: BluetoothTscPrinter.ROTATION.ROTATION_0,
xscal: BluetoothTscPrinter.FONTMUL.MUL_1,
yscal: BluetoothTscPrinter.FONTMUL.MUL_1
}],
}
const SamplePrint = () => {
return (
