I want to print triplicate copies of the invoice with different headers like original, duplicate, and triplicate using HTML javascript. I don't use any library files for pdf. Check out the js code.

    <button type="button" onclick="printDiv('printableArea')" class="btn btn-light btn-sm ml-3"><i class="icon-printer mr-2"></i> Print</button>
 <div id="printableArea">

</div>

  function printDiv(divName) {
                    // Print layout style code
                    var css = '@page { size: A4; }body{font-family: "Times New Roman", Times, serif !important;} .particulars_body{min-height:800px !important;color:red;}',
                        head = document.head || document.getElementsByTagName('head')[0],
                        style = document.createElement('style');

                    style.type = 'text/css';
                    style.media = 'print';

                    if (style.styleSheet) {
                        style.styleSheet.cssText = css;
                    } else {
                        style.appendChild(document.createTextNode(css));
                    }

                    head.appendChild(style);

                    setTimeout(function() {
                        mywindow.print();
                    }, 1000);
                    var printContents = document.getElementById(divName).innerHTML;
                    var originalContents = document.body.innerHTML;
                    document.body.innerHTML = printContents;
                    window.print();
                    document.body.innerHTML = originalContents;
                }
