So I think you want to print a Report without Preview so check this out

in that article youfind following code
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();
dataSet.ReadXml(@"..\..\data.xml");
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);
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>8.5in</PageWidth>" +
" <PageHeight>11in</PageHeight>" +
" <MarginTop>0.25in</MarginTop>" +

" <MarginRight>0.25in</MarginRight>" +
" <MarginBottom>0.25in</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]);
ev.Graphics.DrawImage(pageImage, ev.PageBounds);
m_currentPageIndex++;
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)
return;
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");
return;
}
printDoc.PrintPage += new PrintPageEventHandler(PrintPage);
printDoc.Print();
}

// export the report to an .emf file, and print it.
private void Run()
{

report.ReportPath = @"..\..\Report.rdlc";
report.DataSources.Add(
new ReportDataSource("Sales", LoadSalesData()));
Export(report);
m_currentPageIndex = 0;
Print();
}
public void Dispose()
{
if (m_streams != null)
{
foreach (Stream stream in m_streams)
stream.Close();

}
}
