Printing a Local Report without Preview

Hi, I need to print some local rdlc reports without previewing it and without any print dialogs. I found a code, that makes it, but however, it creates emf files on disk. I need to make some changes to the code, so that it would work without those files (no files written on disk). The solution with emf files is here:
using System;
using System.IO;
using System.Data;
using System.Text;
using System.Drawing.Imaging;
using System.Drawing.Printing;
using System.Collections.Generic;
using System.Windows.Forms;
using Microsoft.Reporting.WinForms;
public class Demo : IDisposable
    private int m_currentPageIndex;
    private IList<Stream> m_streams;
    private DataTable LoadSalesData()
        // Create a new DataSet and read sales data file 
        //    data.xml into the first DataTable.
        DataSet dataSet = new DataSet();
        return dataSet.Tables[0];
    // Routine to provide to the report renderer, in order to
    //    save an image for each page of the report.
    private Stream CreateStream(string name,
      string fileNameExtension, Encoding encoding,
      string mimeType, bool willSeek)
        Stream stream = new FileStream(@"..\..\" + name +
           "." + fileNameExtension, FileMode.Create);
        return stream;
    // Export the given report as an EMF (Enhanced Metafile) file.
    private void Export(LocalReport report)
        string deviceInfo =
          "<DeviceInfo>" +
          "  <OutputFormat>EMF</OutputFormat>" +
          "  <PageWidth>8.5in</PageWidth>" +
          "  <PageHeight>11in</PageHeight>" +
          "  <MarginTop>0.25in</MarginTop>" +
          "  <MarginLeft>0.25in</MarginLeft>" +
          "  <MarginRight>0.25in</MarginRight>" +
          "  <MarginBottom>0.25in</MarginBottom>" +
        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
        ev.Graphics.DrawImage(pageImage, ev.PageBounds);
        ev.HasMorePages = (m_currentPageIndex < m_streams.Count);
    private void Print()
        const string printerName =
           "Microsoft Office Document Image Writer";
        if (m_streams == null || m_streams.Count == 0)
        PrintDocument printDoc = new PrintDocument();
        printDoc.PrinterSettings.PrinterName = printerName;
        if (!printDoc.PrinterSettings.IsValid)
            string msg = String.Format(
               "Can't find printer \"{0}\".", printerName);
            MessageBox.Show(msg, "Print Error");
        printDoc.PrintPage += new PrintPageEventHandler(PrintPage);
    // Create a local report for Report.rdlc, load the data,
    //    export the report to an .emf file, and print it.
    private void Run()
        LocalReport report = new LocalReport();
        report.ReportPath = @"..\..\Report.rdlc";
           new ReportDataSource("Sales", LoadSalesData()));
        m_currentPageIndex = 0;
    public void Dispose()
        if (m_streams != null)
            foreach (Stream stream in m_streams)
            m_streams = null;
    public static void Main(string[] args)
        using (Demo demo = new Demo())

Just change the CreateStream to use a MemoryStream instead of a FileStream.  

If the report is large, then you might run into memory problems.  You can also print to a file, and when the Report is Disposed delete the file as well.
PrintDocument class has a property called PrintController which has a property called IsPreview

But it does not solve the problem with exported files. It only allows the printing with no preview, which is fine, thank you. But the main problem is still there. How do I print a report without exporting it to emf files on disk?
