        if (print == true)
        {
            XpsDocument xpsDocument = new XpsDocument("C:\\FixedDocumentSequence.xps", FileAccess.ReadWrite);

            pDialog.PrintDocument(fixedDocSeq.DocumentPaginator, "Test print job");
        }
    }

Private Sub InvokePrint(ByVal sender As Object, ByVal e As RoutedEventArgs)
