Windows Forms: How to Print RDLC Report without Report Viewer in C#

Creating a new Windows Forms Application project, then drag Button from the Visual Studio toolbox to your winform.

You need to create the PrintToPrinter method allows you to print the local report directly to the printer.

Extension Methods

C# extension methods allow developers to extend the functionality of an existing type without creating a new derived type, recompiling or modifying the original type. The C# extension method is a special type of static method called as if it were a method expressed on the extension type.

The LocalReportExtensions class contains the PrintToPrinter extension method.

namespace Microsoft.Reporting.WinForms
{
    public static class LocalReportExtensions
    {
        public static void PrintToPrinter(this LocalReport report)
        {
            PageSettings pageSettings = new PageSettings();
            pageSettings.PaperSize = report.GetDefaultPageSettings().PaperSize;
            pageSettings.Landscape = report.GetDefaultPageSettings().IsLandscape;
            pageSettings.Margins = report.GetDefaultPageSettings().Margins;
            Print(report, pageSettings);
        }

        public static void Print(this LocalReport report, PageSettings pageSettings)
        {
            string deviceInfo =

            Warning[] warnings;
            var streams = new List<Stream>();
            var pageIndex = 0;
            report.Render("Image", deviceInfo,
                (name, fileNameExtension, encoding, mimeType, willSeek) =>
                {
                    MemoryStream stream = new MemoryStream();
                    streams.Add(stream);
                    return stream;
                }, out warnings);
            foreach (Stream stream in streams)
                stream.Position = 0;
            if (streams == null || streams.Count == 0)
                throw new Exception("No stream to print.");
            using (PrintDocument printDocument = new PrintDocument())
            {
                printDocument.DefaultPageSettings = pageSettings;
                if (!printDocument.PrinterSettings.IsValid)
                    throw new Exception("Can't find the default printer.");
                else
                {
                    printDocument.PrintPage += (sender, e) =>
                    {
                        Metafile pageImage = new Metafile(streams[pageIndex]);
                        Rectangle adjustedRect = new Rectangle(e.PageBounds.Left - (int)e.PageSettings.HardMarginX, e.PageBounds.Top - (int)e.PageSettings.HardMarginY, e.PageBounds.Width, e.PageBounds.Height);
                        e.Graphics.FillRectangle(Brushes.White, adjustedRect);
                        e.Graphics.DrawImage(pageImage, adjustedRect);
                        pageIndex++;
                        e.HasMorePages = (pageIndex < streams.Count);
                        e.Graphics.DrawRectangle(Pens.Red, adjustedRect);
                    };
                    printDocument.EndPrint += (Sender, e) =>
                    {
                        if (streams != null)
                        {
                            foreach (Stream stream in streams)
                                stream.Close();
                            streams = null;
                        }
                    };
                    printDocument.Print();
                }
            }
        }
    }
}

Adding a click event handler to the Print button allows you to print the rdlc report directly to the printer.

private void btnPrint_Click(object sender, EventArgs e)
{
    LocalReport localReport = new LocalReport();
    localReport.ReportPath = Application.StartupPath + "\\Report1.rdlc";
    localReport.PrintToPrinter();
}

To play the demo, you should create a simple rdlc report by right-clicking on your project->Add->New Item->Visual C# Items->Report

After finishing create a new report. You need to open your Report Designer, then drag a TextBox from the Report Toolbox into your local report. Finally, Enter some text to play the demo.

How to print rdlc report multiple copies in C#

If you want to print multiple copies or set your printer name, you can modify your code as shown below.

PageSettings pageSettings = new PageSettings();
pageSettings.PrinterSettings.Copies = 5;
pageSettings.PrinterSettings.PrinterName = "Your Printer Name";
//...

You can also change your report to Landscape.

PageSettings pageSettings = new PageSettings();
pageSettings.Landscape = true;
//...

Or set up duplex printing, page orientation, collation...etc

PageSettings pageSettings = new PageSettings();
pageSettings.PrinterSettings.Duplex = Duplex.Simplex;
