印刷したウェブページの設定がCSSスタイルファイルを参照している場合、スタイルファイルを導入する必要があります.修正した方法は以下の通りです.
function printDiv(divID,title) {
        
    var links = document.getElementsByTagName("link");

    var styleContent = "";

    for (var i = 0, l = links.length; i < l; i++) {
        var src = links[i].href;

        styleContent += "<link href=\"" + src + "\" rel=\"stylesheet\" type=\"text/css\" />";
    }

    //Get the HTML of div
    var divElements = document.getElementById(divID).innerHTML;
    //Get the HTML of whole page
    var oldPage = document.body.innerHTML;
    
    var titleDiv = "<div style=\"text-align:center;width:100%;\"><h2>" + title + "</h2></div>";

    //Reset the page's HTML with div's HTML only
    document.body.innerHTML =
      "<html><head><title>    </title>" + styleContent + "</head><body>" + titleDiv + 
      divElements + "</body>";
    

    window.print();


    //Restore orignal HTML
    document.body.innerHTML = oldPage;
}
