    if (ret != PrinterStatus.SDK_OK) {
    appendLog(`printer status: ${PrinterStatus.msg(ret)}`);

LCD

const _showLcd = async () => {
  try {
    await NyxPrinter.configLcd(LcdOpt.INIT);
    await NyxPrinter.showLcdBitmap(imageBase64);
  } catch (e) {
      appendLog(`showLcd: ${e}`);
  }
};

const _resetLcd = async () => {
  try {
    await NyxPrinter.configLcd(LcdOpt.INIT);
    await NyxPrinter.configLcd(LcdOpt.RESET);
  } catch (e) {
      appendLog(`resetLcd: ${e}`);
  }
};

const _wakeupLcd = async () => {
  try {
    await NyxPrinter.configLcd(LcdOpt.INIT);
    await NyxPrinter.configLcd(LcdOpt.WAKEUP);
  } catch (e) {
      appendLog(`wakeupLcd: ${e}`);
  }
};

const _sleepLcd = async () => {
  try {
    await NyxPrinter.configLcd(LcdOpt.INIT);
    await NyxPrinter.configLcd(LcdOpt.SLEEP);
  } catch (e) {
      appendLog(`resetLcd: ${e}`);
  }
};

Scanner

• Register scanner result listener

React.useEffect(() => {
  // register scanner listener
  DeviceEventEmitter.addListener('onScanResult', (res) => {
    appendLog(`scan result: ${JSON.stringify(res)}`);
  });
  return () => DeviceEventEmitter.removeAllListeners('onScanResult');
}, []);

• Camera scan

const _cameraScan = async () => {
  try {
    await NyxPrinter.scan({});
  } catch (e) {
    appendLog(`cameraScan: ${e}`);
  }
};

• Infrared scan: By default, infrared scan will be triggered by the side button. Here is the code for soft tirgger

const _infraredScan = async () => {
  try {
    await NyxPrinter.qscScan();
  } catch (e) {
    appendLog(`infraredScan: ${e}`);
  }
};

Cash Box

const _openCashBox = async () => {
  try {
    await NyxPrinter.openCashBox();
  } catch (e) {
    appendLog(`openCashBox: ${e}`);
  }
};
