Cannot send print command to the device

[rishihashbinary]

Hello, I am using Evolute printer (https://www.evolute.in/fintech/impress/) and referring to the code to print receipt, following is my code, i am able to connect to the printer, but when i send printText command, there is no print or action on the printer side.

my app runs on android.

`` BluetoothManager.isBluetoothEnabled().then(enabled => { console.log('Bluetooth Enabled? ', enabled)

  BluetoothManager.enableBluetooth().then(
    r => {
      var paired = []
      if (r && r.length > 0) {
        for (var i = 0; i < r.length; i++) {
          try {
            const bluetoothDevice = JSON.parse(r[i])
            // console.log(bluetoothDevice.name)
            paired.push(bluetoothDevice) // NEED TO PARSE THE DEVICE INFORMATION
            if (bluetoothDevice.name === 'ESBAI4577') {
              setPrinterAddress(bluetoothDevice.address)
              console.log('Printer Address', bluetoothDevice.address)
            }
          } catch (e) {
            //ignore
          }
        }
      }
      // console.log(JSON.stringify(paired))

      BluetoothManager.connect(printerAddress) // the device address scanned.
        .then(
          async s => {
            console.log('Connection Result: ', s)
            await BluetoothEscposPrinter.printerInit()
            await BluetoothEscposPrinter.setBlob(0)
            await BluetoothEscposPrinter.printerLeftSpace(0)
            await BluetoothEscposPrinter.printerAlign(
              BluetoothEscposPrinter.ALIGN.CENTER,
            )
            await BluetoothEscposPrinter.printText(
              '------------------------------\r\n',
              {
                encoding: 'UTF8',
                widthtimes: 0,
                heigthtimes: 0,
                fonttype: 1,
              },
            )
            await BluetoothEscposPrinter.printText(
              'This is another text',
              {},
            )
            await BluetoothEscposPrinter.printText(
              '------------------------------\r\n',
              {},
            )
            await BluetoothEscposPrinter.printText('\n\r\n\r\n\r', {})
            console.log('Sent command to the printer')
          },
          e => {
            // this.setState({
            //   loading: false,
            // });
            alert(e)
          },
        )
    },
    err => {
      alert(err)
    },
  )

Hi @rishihashbinary did you manage to solve this? I'm having the same problem with a brother QL-820NWB printer. The printer is recognized, successfully connected and no error is shown on print command but nothing is printed, no action at all in the printer. Thanks
