Sending data to printer
提问by Marin Horvat

Simply use window.print().
Example in jQuery:
只需使用window.print().
jQuery 中的示例：
<script>
$(function() {
$("#print").click(function() {
window.print();
});
});
</script>
<a id='print'>Print ME</a>
Example in JavaScript:
JavaScript 中的示例：
<script>
function printMe() {
window.print()
}
</script>
<input type="button" value="Print" onclick="printMe()">

Aside from window.print()it should be noted that JavaScript can't send the data to the printer directly - it can prompt the print dialog for you though. IE6 used to allow that, and visiting certain sites would make for surprises in your printer tray later that evening.
除了window.print()应该注意的是，JavaScript 不能直接将数据发送到打印机 - 不过它可以为您提示打印对话框。IE6 曾经允许这样做，并且访问某些站点会在那天晚上晚些时候在您的打印机托盘中产生惊喜。
You can bypass the print dialog with a browser plugin.
您可以使用浏览器插件绕过打印对话框。
