<script>
function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
}
</script>

<div id="printableArea">
<input type="text" >
</div>
<input type="button" onclick="printDiv('printableArea')" value="print a div!" />

    I have altered your code to retain the textbox value:

    <html>
<head>
<script>
function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
var text=document.getElementById("t1").value;
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
document.getElementById("t1").value=text;
}
</script>
</head>
<body>
<div id="printableArea">
<input type="text" id="t1">
</div>
<input type="button" onclick="printDiv('printableArea')" value="print a div!" /> 
</body>
</html>
