I have the following:
<iframe src="ACRBusinessCL.pdf" id="PDFtoPrint" height="800" width="800">
</iframe>
<form>
<input type="button" value="Print" onclick="document.getElementById('PDFtoPrint').focus(); document.getElementById('PDFtoPrint').contentWindow.print();">
</form>
What's driving me crazy is: I thought I had this working at one point. The pdf file is showing up in the iframe, but when I click Print, nothing happens.
