How to directly print rdlc report without showing PrintDialog() in C#?

I have an application where I have to print a RDLC report without showing the printDialog and using the default specified printer defined in the application. Below is my test implementaion code.

    Microsoft.Reporting.WinForms.ReportViewer reportViewerSales = new    Microsoft.Reporting.WinForms.ReportViewer();
    Microsoft.Reporting.WinForms.ReportDataSource reportDataSourceSales = new Microsoft.Reporting.WinForms.ReportDataSource();

    reportViewerSales.Reset();
        reportViewerSales.LocalReport.ReportPath = @"Sales.rdlc";

        reportDataSourceSales.Name = "SalesTableDataSet";

        int i = 1;
        foreach (Product item in ProductSalesList)
        {
            dataset.CurrentSales.AddCurrentSalesRow(i, item.Name, item.Quantity.ToString(), item.Price.ToString(), item.Price.ToString());
            i++;
        }
        reportDataSourceSales.Value = dataset.CurrentSales;
        reportViewerSales.LocalReport.DataSources.Add(reportDataSourceSales);
        dataset.EndInit();

        reportViewerSales.RefreshReport();
        reportViewerSales.RenderingComplete += new RenderingCompleteEventHandler(PrintSales);

And here is my Rendering Complete Method

public void PrintSales(object sender, RenderingCompleteEventArgs e)
    {
        try
        {

            reportViewerSales.PrintDialog();
            reportViewerSales.Clear();
            reportViewerSales.LocalReport.ReleaseSandboxAppDomain();
        }
        catch (Exception ex)
        {
        }
    }

i have made an extension class to @tezzos answer. which might make it more easier.

use this Gist Here to get the extension class i wrote. include it to your project. don't for get namespace :D

LocalReport report = new LocalReport();
            report.ReportEmbeddedResource = "Your.Reports.Path.rdlc";
            report.DataSources.Add(new ReportDataSource("DataSet1", getYourDatasource()));
            report.PrintToPrinter();

PrintToPrinter Method will be available on LocalReport. Might Help someone

I just gave a quick look to a class I created to print directly and I think I took some ideas from this walkthrough: Printing a Local Report without Preview
