No printers installed error

    Question

  • Hello All...

    I'm using the following VB 2008 code which to me seems pretty straightforward.

        If myAppSettings.ReceiptPrinter.Length = 0 Then
          Dim pd As New PrintDialog()
          pd.PrinterSettings = New Printing.PrinterSettings()
          If pd.ShowDialog() = DialogResult.Cancel Then Return
          myAppSettings.ReceiptPrinter = pd.PrinterSettings.PrinterName
        End If

    The dialog displays with my printers listed and the default printer selected. When I click the Properties button, nothing happens. When I close the dialog, I get an ArgumentException "Handle 0 is not valid." Looking at the pd object, any property that references a printer setting displays "No Printers are Installed."

    I can enumerate through the printers using this code and they are all listed.

        For i As Integer = 0 To PrinterSettings.InstalledPrinters.Count - 1
          myPrinters += PrinterSettings.InstalledPrinters.Item(i) & vbCrLf
        Next

    And this code return an error "No Default Printer Specified."

        Dim ps As New Printing.PrinterSettings
        myPrinter = ps.PrinterName

    All of my printers are network printers.

    Does anyone have any idea why this is happening and how to correct it?

    Thanks everyone..
