window.print打印指定div
首先我们可以把要打印的内容放在div中,然后用下面的代码进行打印。

<html>
<head>
<script language="javascript">
function printdiv(printpage)
{
  var headstr = "<html><head><title></title></head><body>";
  var footstr = "</body>";
  var newstr = document.all.item(printpage).innerHTML;
  var oldstr = document.body.innerHTML;
  document.body.innerHTML = headstr+newstr+footstr;
  window.print();
  document.body.innerHTML = oldstr;
  return false;
}
</script>
<title>div print</title>
</head>

<body>
//HTML Page
//Other content you wouldn't like to print
<input name="b_print" type="button" class="ipt" onClick="printdiv('div_print');" value=" Print ">

<div id="div_print">

<h1 style="Color:Red">The Div content which you want to print</h1>

</div>
//Other content you wouldn't like to print
//Other content you wouldn't like to print
</body>
</html>
