I use Zebra IMZ320 bluetooth printer and I try to print text via LinkOS.Plugin in Xamarin IOS. But its unable to print using the sample code which you gave.http://techdocs.zebra.com/link-os/2-13/xamarin/
I have attached my code and error herewith.
public void SendTotalPrint()
{
string message = "";
IConnection connection = null;
connection = ConnectionBuilder.Current.Build("BT:XXXXJ165202255");
//await Task.Run(() => {
connection.Initialize("BT:XXXXJ165202255");
connection.TimeToWaitAfterWrite = 4000;
IDiscoveryEventHandler handler = DiscoveryHandlerFactory.Current.GetInstance();
handler.OnDiscoveryError += DiscoveryHandler_OnDiscoveryError;
handler.OnDiscoveryFinished += DiscoveryHandler_OnDiscoveryFinished;
handler.OnFoundPrinter += DiscoveryHandler_OnFoundPrinter;
BluetoothDiscoverer.Current.FindPrinters(null, handler);
try
{
connection.Open();
IZebraPrinter printer = ZebraPrinterFactory.Current.GetInstance(PrinterLanguage.ZPL, connection);
string pl = printer.PrinterControlLanguage.ToString();
string zpl = "^XA^POI^MNN^LL90^PW400^FO20,20^A0N,50,50^FDTEST^FS^XZ";
connection.Write(Encoding.UTF8.GetBytes(zpl));
}
catch (Exception e)
{
message = "Exception: " + (e.Message);
}
finally
{
if ((connection != null) && (connection.IsConnected))
{
connection.Close();
}
}
}
Error occur in connection.Write(Encoding.UTF8.GetBytes(zpl)); as
{LinkOS.Plugin.ConnectionException: Error writing to connection
at LinkOS.Plugin.ConnectionImplementation.Write (System.Byte[] data) [0x00052] in :0
at ZSD.iOS.Interfaces.TotalPrint.SendTotalPrint () [0x000b5]}
I tried both Xamarin PCL and Xamarin.Ios project
