How can JavaScript be utilized to print a PDF file generated by PHP within a web application?

To print a PDF file generated by PHP within a web application using JavaScript, you can create a function that opens a new window and loads the PDF file URL. This can be achieved by using the `window.open()` method in JavaScript. 

<?php
// Generate PDF file here

$pdf_file = 'path/to/generated/pdf.pdf';
?>

<!DOCTYPE html>
<html>
<head>
    <title>Print PDF</title>
    <script>
        function printPDF() {
            var pdfWindow = window.open('<?php echo $pdf_file; ?>', '_blank');
            pdfWindow.print();
        }
    </script>
</head>
<body>
    <button onclick="printPDF()">Print PDF</button>
</body>
</html>
