How to Print PDF Files Silently in ReactJS

In the era where digital documents are essential for business and personal communication, being able to print PDF files seamlessly is crucial. Using ReactJS for your applications can simplify this process, but many developers face a common issue: how to print a PDF file without opening it in a new tab first. If you have found yourself looking for a solution to this problem, you're in the right place. In this guide, we will guide you through the steps to print a PDF file silently directly from your React application.

Understanding the Problem

Typically, when you want to print a PDF file in a web application built with ReactJS, you might follow these steps:

Open the PDF in a new browser tab: This ensures that the PDF is fully loaded.

Trigger the print command: Once the PDF loads, the print dialog appears.

While this is functional, it's not an optimal user experience. Users might find it disruptive to see the PDF open in another tab when they just want to print it. Thus, the goal is to print the PDF directly without the intermediate step of opening a new tab.

Step-by-Step Solution

To achieve silent printing of a PDF file in ReactJS, we will utilize a helpful npm package called print-js. Below, you'll find a clear, step-by-step guide to implement this solution.

Step 1: Install the Required npm Package

First, you need to install the print-js package. This package allows you to print your documents easily and streamlines the process of printing PDFs. You can install it using npm by running the following command in your terminal:

Key Code Explanation:

Import the Package: We import print from print-js to allow us to access its functionality.

Define the PDF URL: Set the URL of the PDF document you wish to print.

Handle Print Event: In the handlePrint function, we prevent the default form submission behavior using e.preventDefault() and then call print(pdfURL) to initiate the print dialog directly.

Step 3: Trigger the Print Action

You can now trigger the handlePrint function through a button or form submission within your React component. For example:

This button, when clicked, will execute the handlePrint function, leading to the PDF being printed directly, without opening a new tab.

Conclusion

By following these simple steps and utilizing the print-js package, you can efficiently print PDF files without the hassle of opening them in a new tab. This not only enhances the user experience but also streamlines the printing process in your ReactJS applications. Whether you're building enterprise solutions or personal projects, seamless PDF printing can greatly improve functionality.

Now that you have this guide, you can easily implement silent PDF printing in your React applications. Happy coding!
