        PrintDialog pDialog = new PrintDialog();
        pDialog.PageRangeSelection = PageRangeSelection.AllPages;
        pDialog.UserPageRangeEnabled = true;

        // Display the dialog. This returns true if the user presses the Print button.
        Nullable<Boolean> print = pDialog.ShowDialog();
        if (print == true)
        {
            XpsDocument xpsDocument = new XpsDocument("C:\\FixedDocumentSequence.xps", FileAccess.ReadWrite);
            FixedDocumentSequence fixedDocSeq = xpsDocument.GetFixedDocumentSequence();
            pDialog.PrintDocument(fixedDocSeq.DocumentPaginator, "Test print job");
        }
    }

Private Sub InvokePrint(ByVal sender As Object, ByVal e As RoutedEventArgs)
        ' Create the print dialog object and set options
        Dim pDialog As New PrintDialog()
        pDialog.PageRangeSelection = PageRangeSelection.AllPages
        pDialog.UserPageRangeEnabled = True

        ' Display the dialog. This returns true if the user presses the Print button.
        Dim print? As Boolean = pDialog.ShowDialog()
        If print = True Then
            Dim xpsDocument As New XpsDocument("C:\FixedDocumentSequence.xps", FileAccess.ReadWrite)
            Dim fixedDocSeq As FixedDocumentSequence = xpsDocument.GetFixedDocumentSequence()
