Here is my code:

string cpclData = "! 0 200 200 210 1\r\n"                        + "TEXT 4 0 30 40 This is a CPCL test.\r\n"                        + "FORM\r\n"                        + "PRINT\r\n";string zplData = "^XA^FO20,20^A0N,25,25^FDThis is a ZPL test.^FS^XZ";ZebraPrinterConnection thePrinterConn = new BluetoothPrinterConnection(Mac);theprinterConn.Open()SGD.SET("device.languages", "ZPL", thePrinterConn);thePrinterConn.Write(Encoding.Default.GetBytes(cpclData));thePrinterConn.Write(Encoding.Default.GetBytes(zplData));
My printer prints only cpclData string.
On zplData there is an empty label.
When I read SGD.GET "device.languages" I got info, that "zpl" is set.
But when I use:
ZebraPrinter myPrinter = ZebraPrinterFactory.GetInstance(myConn); PrinterLanguage myPrinterLanguage = myPrinter.GetPrinterControlLanguage();
I get CPCL. WHY ?
