[SOLVED] Print PDF directly from JavaScript

Print PDF directly from JavaScript

I am building a list of PDFs in HTML. In the list I'd like to include a download link and a print button/link. Is there some way to directly open the Print dialog for the PDF without the user seeing the PDF or opening a PDF viewer?

Some variation of downloading the PDF into a hidden iframe and triggering it to print with JavaScript?

Solution

Based on comments below, it no longer works in modern browsers
This question demonstrates an approach that might be helpful to you: Silent print an embedded PDF

It uses the <embed> tag to embed the PDF in the document:

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

Then you call the .print() method on the element in Javascript when the PDF is loaded:

function printDocument(documentId) {
    var doc = document.getElementById(documentId);

    //Wait until PDF is ready to print    
    if (typeof doc.print === 'undefined') {    
        setTimeout(function(){printDocument(documentId);}, 1000);
    } else {
        doc.print();
    }
}

You could place the embed in a hidden iframe and print it from there, giving you a seamless experience.
