Save MS Dynamics CRM Records as PDF

Question

Recently, I had been asked by a client that they require to download all CRM Records of all entity as PDF.

I tried with html2canvas and jspdf libraries , but i was not able to download the form completely(form was scroll-able), It gave me only what i was able to currently see, not the remaining scrollable part.

Please guide me if i am doing something wrong in the below code or there is any other way to do so.

function createPDF() {
    var a4 = [595.28, 841.89];

        var div = $('#HeaderTilesWrapperLayoutElement', window.parent.document);

        var xxxx = $($(div.context).find('iframe')[0]).contents().find("body");

        var xxx = xxxx.find("#tdAreas");
        var cache_width = xxx.width();

        $('body').scrollTop(0);
        getCanvas().then(function (canvas) {
            var
             img = canvas.toDataURL("image/png"),
             doc = new jsPDF({
                 unit: 'px',
                 format: 'a4'
             });
            doc.addImage(img, 'JPEG', 20, 20);
            doc.save('techumber-html-to-pdf.pdf');
             xxx.width((a4[0] * 1.33333) - 80).css('max-width', 'none');
        });
    }

    // create canvas object
    function getCanvas() {
        xxx.width((a4[0] * 1.33333) - 80).css('max-width', 'none');
        return html2canvas(xxx, {
            imageTimeout: 2000,
            removeContainer: true
        });
    }
