Print SSRS Reports in ASP.NET Core with Report Writer and PrintJS

ASP.NET Core is a popular framework for building web applications that can run on various platforms, and one of the requirements for many web applications is to generate and print SSRS reports. In this blog, we will explore how to generate and print SSRS reports using Bold Reports’ Report Writer and PrintJS in an ASP.NET Core application. We’ll discuss the benefits of using Bold Reports ASP.NET Core Report Writer, a powerful reporting tool that allows developers to create and design sophisticated reports using various data sources. Additionally, we’ll learn how PrintJS, a lightweight and straightforward library, can facilitate the printing of PDF files generated from RDL reports using Bold Reports Report Writer.

Let’s dive in!


 Ensure your development environment includes the following:

  1. Visual Studio Code
  2. .NET6.0 SDK (or) Higher.

Create an ASP.NET Core 6 application

  1. Open Visual Studio Code and go to the terminal menu; click on the New Terminal menu item.
  2. Create an ASP.NET Core Web MVC application. On executing the following command, the ASP.NET Core Web App (MVC) template will be created.

    dotnet new mvc --framework net6.0 --name CoreReportWriter
  3. The ASP.Net Core Web App (MVC) is created.

    Create a new .NET 6 project.
    Create a new .NET 6 project.

Install the NuGet Packages

  1. To use the Bold Reports Report Writer library in your project, you need to install the BoldReports.Net.Core NuGet package.
  2. Run the following commands to install the BoldReports.Net.Core NuGet package in the application.
    cd CoreReportWriter
    dotnet add package BoldReports.Net.Core

Install Print.js package

  1. First, you need to install Print.js in your ASP.NET Core project to use the PrintJS related APIs. You can install it using npm or by downloading it from the Print.js website.
  2. To install it using npm, in your project’s Terminal, run the following command.
     npm install print-js

Create a controller action to Print SSRS reports

Next, you need to create a controller action that generates and prints SSRS reports in PDF format.

  1. Open the Controllers/HomeController.cs file and create local variables inside the HomeController class, like the following.
    private Microsoft.AspNetCore.Hosting.IWebHostEnvironment _hostingEnvironment;
    public HomeController(Microsoft.AspNetCore.Hosting.IWebHostEnvironment hostingEnvironment)
        _hostingEnvironment = hostingEnvironment;
  2. Add the PrintPDF() function to create a FileStream object called inputStream to open the “sales-order-detail.rdl” file in read-only mode. Refer to the following code snippet.

    public IActionResult PrintPDF()
         var rdlPath = "\\Resources\\sales-order-detail.rdl";
         FileStream inputStream = new(_hostingEnvironment.WebRootPath + 
  3. To generate the SSRS RDL report as a PDF, pass the file stream object to the Bold Reports Report Writer’s LoadReport method and call the Save method to save it as a PDF file. The following code does this.
    BoldReports.Writer.ReportWriter writer = new();
    using MemoryStream memoryStream = new();
    writer.Save(memoryStream, BoldReports.Writer.WriterFormat.PDF);
    return File(memoryStream.ToArray(), "application/pdf", "example.pdf");

    This will pass the report as a PDF to the client side.

Initialize Print.js to print the PDFs

To print the PDF files generated from the server side to the client side, you need to use Print.js’s printJS API in your cshtml page.

  1. Open the Views/Home/Index.cshtml page.
  2. Remove the existing div code and add the following code. This will create a button to print the PDF file.
    <button id="print-SSRS-reports">Print SSRS reports</button>
  3. Since I already installed the print-js package, to make this sample simple, I am copying and pasting the print.js file from the node_modules/print-js/dist folder to the wwwroot/js folder in my application.
  4. Now, I can use the print.js file in my Index.cshtml file and call the printJS method to save the server side’s file object as a PDF file on the client side. To do this, in the Index.cshtml page, add a Scripts section and add the print.js location path. Call the server side’s PrintPDF method and get the file and pass the file object to the printJS() method to save it as a PDF. The following code explains this.
    @section Scripts {
       <script src= "~/js/print.js"></script>
         document.getElementById("print-SSRS-reports").addEventListener("click", function () {
           fetch("/Home/PrintPDF").then(response => response.blob()).then(blob => {
               printJS({ printable: URL.createObjectURL(blob), type: "pdf" });

Add already created reports

  1. Create a Resources folder in the wwwroot folder in your application to store the RDL reports.
  2. Download the sales-order-detail.rdl file from here. For more sample reports, refer to the samples and demos section.
  3. Extract the compressed file and paste the sales-order-detail.rdl file to the Resources folder.

Run the application to print SSRS reports using PrintJS

Run the application and click the “Print SSRS reports” button. The print page will automatically open, allowing you to print the SSRS report file.
