How to pass the PDF header through Javascript/jQuery?

I need to print a page, IE, when the user accesses it, it already sends the PDF header and sends it to download. How to do this by JS?

To syntax to send a request header with jQuery would be:

$.ajax({

    url: "/path/to/file.ext",
    beforeSend: function( xhr ) {

        xhr.setRequestHeader( 'Content-type', 'application/pdf' );
    }

}).done( function( response ) {

    // Dom something
})

However, unless mistaken, this will not have the intended result as it is a Request Header, that is, it indicates to the receiving program, defined in the AJAX URL that a PDF request would be made, rather than a Response Header that tells the browser to treat that output as a PDF.

I’ve never seen any practical application, but I imagine sending that Request Header would allow the receiving application to work with the raw data ("raw data") of the request.
