Can JavaScript Print PDFs Directly, Without User Interaction?

Printing PDFs Directly from JavaScript

Embedding PDFs in HTML lists often requires a download link and a print button or link. Can we directly open the Print dialog for the PDF without revealing the document itself or using a PDF viewer?

A potential solution involves using a hidden iframe. Here's how it works:

1. Embed the PDF in a hidden iframe using the tag:

   <code class="html"><embed
       type="application/pdf"
       src="path_to_pdf_document.pdf"
       id="pdfDocument"
       width="100%"
       height="100%"
   /></code>

2. Define a JavaScript function to print the document:

   <code class="javascript">function printDocument(documentId) {
       var doc = document.getElementById(documentId);
   
       // Wait until PDF is ready
       if (typeof doc.print === 'undefined') {
           setTimeout(function() { printDocument(documentId); }, 1000);
       } else {
           doc.print();
       }
   }</code>

3. Call the printDocument() function when the PDF is loaded.

By using a hidden iframe, you can seamlessly print the PDF without the user seeing it or opening a PDF viewer.
