The Node.js PDF Library
The Portable Document Format (PDF) was developed by Adobe for the purpose of sharing documents with text and graphics. An additional program is needed in order to open a PDF document online. PDF files are very important for critical information in today's society. Many businesses create documents and invoices using PDF files. To meet client needs, developers produce PDF documents. It has never been easier to create PDFs thanks to modern libraries.
To select the ideal library for a project that uses this kind of library, we must weigh a number of factors, including build, read, and conversion capabilities.
In this tutorial, we'll go through a variety of JavaScript libraries for producing PDFs. We'll analyze the JS library and real-world application scenarios while focusing on three main points:
After reading this, you'll be able to select the ideal PDF library for your JavaScript application. Finally, we'll also cover IronPDF, a useful and effective PDF library.
printJS method and pass the element ID to the printable propertyPrint methodConsider the scenario where we want the customer to be able to download and print a copy of our invoice. We need this invoice to print accurately and in a suitable manner. Here, we'll take a closer look at a few of the many libraries that are available for converting this invoice from the HTML file format to PDF.
Normally, to print a PDF file's contents, we download it to our computer, open it, and select the print option. JavaScript, on the other hand, makes it simple to print a PDF file directly from a web page. All you need is an iframe on your website or the ability to dynamically build one, add the document, and print it. I'll demonstrate how to use JavaScript to print a PDF file. A web page inside another web page is shown using an iframe. For the web page to display, the iframe has to know its source.
<html>
<head>
<title>javascript print pdf</title>
</head>
<body>
<iframe
src="Demo.pdf" id="myFrame"
frameborder="0" style="border:0;"
width="300" height="300">
</iframe>
<p>
<input type="button" id="bt" onclick="print()" value="Print PDF" />
</p>
</body>
<script>
let print = () => {
let objFra = document.getElementById('myFrame');
objFra.contentWindow.focus();
objFra.contentWindow.print();
}
</script>
</html><html>
<head>
<title>javascript print pdf</title>
</head>
<body>
<iframe
src="Demo.pdf" id="myFrame"
frameborder="0" style="border:0;"
width="300" height="300">
</iframe>
<p>
<input type="button" id="bt" onclick="print()" value="Print PDF" />
</p>
</body>
<script>
let print = () => {
let objFra = document.getElementById('myFrame');
objFra.contentWindow.focus();
objFra.contentWindow.print();
}
</script>
</html>As for printing PDF, a document's contents can be displayed using an iframe, and then the contents can be printed using JavaScript. In both situations, an iframe is required. In the example above, there is an iframe with a source (the PDF). There is also a button-type input element.
The button's onclick property will invoke the print method.
Print.js was primarily created to enable us to print PDF files from within our apps without having to navigate away, import and print them from the user interface, or use embeds. This is for special circumstances where users only need to print the PDF files and don't need to open or download them.
When users ask to print reports that are generated on the server side, for instance, this can be helpful. These reports are returned to you as PDF documents. These files can be printed without needing to be opened. Within our apps, Print.js provides a convenient way to print these files.

})();For more code examples on PDF related tasks, please visit this IronPDF Code Examples for Node.js page.
The user can see the JavaScript code above, but it could be abused by others. The use of the source code in this manner is possible. Additionally, it is not difficult to add code to the website that endangers the security of data sent through it. The aforementioned JavaScript library is viewed differently by different browsers. The code must therefore run across a variety of systems before being released. Because some new functionalities are not supported by older browsers, we also need to look at browser compatibility for those. The libraries mentioned above can produce PDF files. The user must also have some familiarity with the script they are working with.
