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.Reset();
                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.DataSources.Clear();        
                  
                ReportViewer.LocalReport.ReportEmbeddedResource = "PrintForm.rdlc";
         
                ReportViewer.LocalReport.DataSources.Add(reportDataSource);


                Export(ReportViewer.LocalReport);


                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)
                    stream.Close();
                m_streams = null;
            }
        }


        private Stream CreateStream(string name,
      string fileNameExtension, Encoding encoding,
      string mimeType, bool willSeek)
        {
            Stream stream = new MemoryStream();
            m_streams.Add(stream);
            return stream;
        }
        // Export the given report as an EMF (Enhanced Metafile) file.
        private void Export(LocalReport report)
        {
            string deviceInfo =
              @"<DeviceInfo>
                <OutputFormat>EMF</OutputFormat>
                <PageWidth>210mm</PageWidth>
                <PageHeight>280mm</PageHeight>
                <MarginTop>0.1in</MarginTop>
                <MarginLeft>0in</MarginLeft>
                <MarginRight>0in</MarginRight>
                <MarginBottom>0in</MarginBottom>
            </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
               Metafile(m_streams[m_currentPageIndex]);


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


            // 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.
            m_currentPageIndex++;
            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.");
            }
            else
            {
                printDoc.PrintPage += new PrintPageEventHandler(PrintPage);
                m_currentPageIndex = 0;
                printDoc.Print();
            }
        }


        #endregion
