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 abc.View.MainView.ReaderFormLoad(Object sender, EventArgs e)
   at System.Windows.Forms.Form.OnLoad(EventArgs e)
   at System.Windows.Forms.Form._SetVisibleNotify(Boolean fVis)
   at System.Windows.Forms.Control.set_Visible(Boolean value)
   at System.Windows.Forms.Application.Run(Form fm)
   at abc.abc.Program.Main().
 
What am I missing?
Thanks,
Gopal
