    <style type="text/css" media="print">
        @page /* 实现代码 */
        {
            size: auto;   /* auto is the initial value */
            margin: 0mm;  /* this affects the margin in the printer settings */
        }
        body /* 设置打印范围的边距，不设置打印内容会顶着最上边 */
        {
            background-color:#FFFFFF; 
            border: solid 0px black ;
            margin: 50px;  /* this affects the margin on the content before sending to printer */
        }
