Link to send pdf straight to printer dialog

问题

I've tried the following 2 methods..

<embed src="assets/pdf/mypdf.pdf" id="Pdf1" name="Pdf1" hidden="true">

<a class="print" onClick="document.Pdf1.printWithDialog();"></a>

<a onClick="document.getElementById('Pdf1').printWithDialog()" style="cursor:hand;">Print file</a>

Another attempt..

<script type="text/javascript">
function printPDF(pdfUrl) 
{
    var w = window.open(pdfUrl);
    w.print();
}
</script>

<a class="print" onClick="printPDF("assets/pdf/mypdf.pdf");">a</a>

None seem to work. Any solution so I can click a link and it sends the pdf to the print dialog? window.print just brings up the actual site in the dialog, not the pdf.
