    Failed to open the usb port LPT1

      Hi,

      I am trying to print some text from MK500(windows CE5.0) to QL220 Plus and QLn220.

       

      MK500 to QL220 Plus is working fine. But when I connect to Qln220 I get following error while opening the connection.

       

      Failed to open the USB port: LPT1: ,Stack Trace -   at ZSDK_API.Comm.UsbPrinterConnection.Open()

         at abc.ZebraPrint.InitializePrinterConnection()

         at abc.ZebraPrint..ctor()

         at abc.ZebraPrint.GetInstance()

         at abc.PortPanelPresenter..ctor(IView view)

         at System.Windows.Forms.Application.Run(Form fm)

         at abc.abc.Program.Main().

       

      What am I missing?

      Thanks,

      Gopal
