Doubt in a jquery with div print

Next question, I have a javascript code that makes it impression of a div by id, but the following is a form, I would like to customize with header and images, it is possible without me having to insert the data into the div ?

La goes the script:

<script type = 'text/javascript'>
 $(document).ready(function(){
    //IMPRESSÃO - A O CONTEUDO QUE SERÁ IMPRESSO DEVERA ESTAR DENTRO DE UMA //DIV CHAMADA print
    $("#imprimir").click(function () {        
    $("#botoes").hide();       
    $("#print").show();
    window.print();         
    $("#botoes").show();       
});
EXPORTAR PARA PDF - O CONTEUDO DA EXPORTAÇÃO DEVERÁ ESTAR DENTRO DE UMA DIV CHAMADA PRINT
$("#pdf").click(function () {
      var pdf = new jsPDF('p','pt','letter');
        var specialElementHandlers = {
            '#print': function (element, renderer) {
            return true;
        }
    };
    pdf.addHTML($('#print').first(), function() {
        pdf.save("RelatorioPdf.pdf");
    });
});   
EXPORTAR EXCEL - O CONTEUDO DA EXPORTAÇÃO DEVERÁ ESTAR DENTRO DE UMA DIV CHAMADA PRINT
$("#excel").click(function () {
    var htmltable= document.getElementById('print');
    var html = htmltable.outerHTML;
    window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));
});

});

There is another doubt taking advantage of, how do I apply UTF-8 to this export? Doubt beast I know, but I am only a new Padawan in this area of development. Thanks and thank you for being able to help.
