SDG command to get printed tag count while printing not working.

Hi Axel,

I think they made a change to the SDK recently that will make it problematic to use the SGD class with an Xi printer.  It will only work on Link-OS printers now.

Please switch your code to use something like the following instead:

connection.open();
string getFW = "\r\n! U1 getvar \"appl.name\"\r\n";
string getRFIDValid = "\r\n! U1 getvar \"odometer.rfid.valid_resettable\"\r\n";
byte[] fwResp = connection.sendAndWaitForResponse(getFW.getBytes("UTF-8"), 300,300, null);
val firmwareVercion = new String(fwResp, "UTF-8");
byte[] rvResp = connection.sendAndWaitForResponse(getRFIDValid.getBytes("UTF-8"), 300,300, null);
val count = new String(rvResp, "UTF-8");
