单击按钮后更改打印样式

Question

This:

<link id="printstyle" href="oldprintstyle.css" rel="stylesheet" type="text/css" media="print" />

$('#printStyle2').click(function () {
    $("#printstyle").attr('href', _printStyle2);
    window.print();
    return false;
});

kind of works. I say kind of, as the actual print style is only applied after I click the button with the id 'printStyle2' a second time. What could be the reason for this behavior? Some kind of caching of the old print style?

The browser needs indeed some time to apply all the changes. So:

window.setTimeout(function() { window.print(); }, 1000);

does the trick.
