c# – TransactionPrint Method of POSPrinter throws Exception

we have a Kiosk Application and print using the Microsoft.PointOfService SDK. In our development environment everything works. But on the customer machine (same printer/SDK/application) we get the following Error:

UPOSDevice | Method TransactionPrint threw an exception.  Service Object specific error. | Microsoft.PointOfService.PosControlException: Method TransactionPrint threw an exception.  Service Object specific error.
   at Microsoft.PointOfService.Legacy.LegacyProxy.ThrowLegacyMethodException(String methodName, Int32 ResultCode, Exception e)
   at Microsoft.PointOfService.Legacy.LegacyProxy.InvokeMethod(String methodName, Object[]& parameters, Boolean[] byRef)

   at Microsoft.PointOfService.Legacy.LegacyProxy.InvokeMethodAndCheck(String methodName, Object param1, Object param2)
   at Microsoft.PointOfService.Legacy.LegacyPosPrinter.TransactionPrint(PrinterStation station, PrinterTransactionControl control)
   at UPOSPosPrinter.EndTransaction(PrinterStation station)
ErrorCode: 65535
ErrorCodeExtended: -1

I couldn’t even find a defintion for the ErrorCode: 65535. Does somebody know what the problem is or at least what the ErrorCode stands for?

The log from POsforNET:
