I can't get instance of pos printer
===

I'm working on EPOS pos printer (EPOS TM-T88III). İ stalled it's driver, EPOS ADK and POS for .NET I can get print from my pos printer with PrintDocument function but i want to use EPOS ADK. I try its "Hello OPOS for .NET" sample but it's not work. 
Because,

    deviceInfo = posExplorer.GetDevice(DeviceType.PosPrinter, strLogicalName)
    m_Printer = posExplorer.CreateInstance(deviceInfo) 

i can get deviceInfo but, posExplorer.CreateInstance(deviceInfo)  returns nothing. Icant solve this problem. 
How can i solve this problem to succeed returns something from posExplorer.CreateInstance(deviceInfo) or is there anyway or sample code to use EPOS ADK to print something.
