    Failed to open the usb port LPT1

    Gopal Chauhan


      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()

      What am I missing?
