Javascript Print to PDF

If you are looking for a way to print your web page or document as a PDF in Javascript, there are several ways to do it.

Using jsPDF Library

One of the most popular libraries for creating a PDF from HTML in Javascript is jsPDF. It is an open-source library that can be used to generate PDF documents directly from client-side Javascript. The library provides many features such as adding text, images, tables, and more to the generated PDF document.

Here is an example of how to use jsPDF:

  // Create a new jsPDF instance
  var doc = new jsPDF();
  // Add text to the PDF
  doc.text('Hello, world!', 10, 10);
  // Save the PDF'example.pdf');

Using PDF.js Library

Another option is to use the PDF.js library, which is an open-source library created by Mozilla that allows you to render PDF files using Javascript. With this library, you can load a PDF file and then use its API to write on it, create annotations, and more.

Here is an example of how to use PDF.js:

  // Load the PDF file
  PDFJS.getDocument('example.pdf').then(function(pdf) {
    // Get the first page
    pdf.getPage(1).then(function(page) {
      // Create a canvas element
      var canvas = document.createElement('canvas');
      var context = canvas.getContext('2d');
      // Set canvas dimensions
      var viewport = page.getViewport(1.0);
      canvas.width = viewport.width;
      canvas.height = viewport.height;
      // Render the page
        canvasContext: context,
        viewport: viewport
      }).then(function() {
        // Convert the canvas to an image
        var dataURL = canvas.toDataURL('image/png');
        // Create a new window and write the image to it
        var newWindow =;
        newWindow.document.write('<img src="' + dataURL + '" />');

These are just two options for printing to PDF using Javascript. Depending on your project requirements, one of these libraries may be more suitable than the other.
