How to avoid Restart Bluetooth Printer after print?

Question

I have developed windows mobile 6.1 application which search nearby Bluetooth devices and send files.Also I did print functionality to print document on Bluetooth printer.

First time print functionality is working perfectly fine but when I print the document again, then I need to restart the printer and then after it will print.

Is there any solution to avoid restart printer??

Below is my print code from reference of https://32feet.codeplex.com/discussions/355451

private void btPrint_Click(object sender, EventArgs e)
    {            
        // Activate BT
        BluetoothRadio.PrimaryRadio.Mode = RadioMode.Connectable;
        System.Threading.Thread.Sleep(1000);
        // Connect  
        BluetoothAddress btAddress;
        btAddress = BluetoothAddress.Parse("0022583165F7");            
        BluetoothClient btClient = new BluetoothClient();
        try
        {
            btClient.Connect(new BluetoothEndPoint(btAddress, BluetoothService.SerialPort));
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
            return;
        }
        // Send data
        string CPCLStr1 =
            "! 0 200 200 210 1" + Environment.NewLine +
            "ML 25" + Environment.NewLine +
            "TEXT 7 0 10 20" + Environment.NewLine +
            "Just" + Environment.NewLine +
            "Testing" + Environment.NewLine +
            "ENDML" + Environment.NewLine +
            "FORM" + Environment.NewLine +
            "PRINT" + Environment.NewLine;

        // Convert CPCL String to byte array
        byte[] CPCLbytes1 = ASCIIEncoding.ASCII.GetBytes(CPCLStr1);

        NetworkStream ns = btClient.GetStream();
        ns.Write(CPCLbytes1, 0, CPCLbytes1.Length);

        btClient.Close();
    }

Although you close the client stream, the printer seems to wait some time before it resets it's session.

Try to send a <EOF> or <EOT> byte at the end.

Acording to CPCL reference guide there is no simple reset command as with ESC/p for example ({esc}@).

Doing a device reset after every print seems an overkill.

EDIT: SDK sample for sendFile:

                Byte[] cpclLabel = Encoding.Default.GetBytes("! 0 200 200 406 1\r\n" + "ON-FEED IGNORE\r\n"
                + "BOX 20 20 380 380 8\r\n"
                + "T 0 6 137 177 TEST\r\n"
                + "PRINT\r\n");

The above runs fine on my RW420 without the need to reset between prints.
