Direct printing in C# windows application

Just wanna share with u all about the direct printing in the C# windows application. This is little bit tricky for me at first because there are so many things about printing in C# that I need to learn. So, here is my code for direct printing. You can design your report in rdlc.

private void Print_Click(object sender, EventArgs e)
BasePrint printForm = new BasePrint();
                ReportDataSource reportDataSource = new ReportDataSource();

                printForm.Report.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local;
                reportDataSource.Name = "General_PPT_pptAcception"; <--link to the object for data (the  namespace: General.PPT.pptAcception

                DataTable dt = Util.ConvertDataTable(pptTerima);
                reportDataSource.Value = dt;

                ReportViewer ReportViewer = new ReportViewer();

                ReportViewer.LocalReport.ReportEmbeddedResource = "PrintForm.rdlc";


                Print(Convert.ToInt16(Copy.Text.Trim())); <--number of copy


Also include all this code:

    #region direct printing
        public void Dispose()
            if (m_streams != null)
                foreach (Stream stream in m_streams)
                m_streams = null;

        private Stream CreateStream(string name,
      string fileNameExtension, Encoding encoding,
      string mimeType, bool willSeek)
            Stream stream = new MemoryStream();
            return stream;
        // Export the given report as an EMF (Enhanced Metafile) file.
        private void Export(LocalReport report)
            string deviceInfo =
            Warning[] warnings;
            m_streams = new List<Stream>();
            report.Render("Image", deviceInfo, CreateStream,
               out warnings);
            foreach (Stream stream in m_streams)
                stream.Position = 0;
        // Handler for PrintPageEvents
        private void PrintPage(object sender, PrintPageEventArgs ev)
            Metafile pageImage = new

            // Adjust rectangular area with printer margins.
            Rectangle adjustedRect = new Rectangle(
                ev.PageBounds.Left - (int)ev.PageSettings.HardMarginX,
                ev.PageBounds.Top - (int)ev.PageSettings.HardMarginY,

            // Draw a white background for the report
            ev.Graphics.FillRectangle(Brushes.White, adjustedRect);

            // Draw the report content
            ev.Graphics.DrawImage(pageImage, adjustedRect);

            // Prepare for the next page. Make sure we haven't hit the end.
            ev.HasMorePages = (m_currentPageIndex < m_streams.Count);

        private void Print(short pages)
            if (m_streams == null || m_streams.Count == 0)
                throw new Exception("Error: no stream to print.");
            PrintDocument printDoc = new PrintDocument();
            printDoc.PrinterSettings.Copies = pages;
            if (!printDoc.PrinterSettings.IsValid)
                throw new Exception("Error: cannot find the default printer.");
                printDoc.PrintPage += new PrintPageEventHandler(PrintPage);
                m_currentPageIndex = 0;

  1. Thanks for the post!! I have a rdlc report which is then converted to a PDF of one page and is used as label, Now the problem is that i want to get multiple copies of the same page and the page number should be displayed in the format i.e.1/5,2/5... below every copies of the page! Please suggest!! Thanks in advance!!
