How to set options using the PHP wrapper

I'm using the PHP wrapper with PrinceXML 12.5 and the options I'm using don't seem to be working. For example, I've tried various examples of:

$prince->setPageMargin('.5in'); //tried 1in, 20mm, 50mm, etc.
$prince->setPageSize('legal'); //tried letter, legal, 8.5in 14in, etc.

Yet the margins and page size never change. Is there a trick to doing this?
Are there any CSS @page rules that could be overriding them?
Yes, that was it. I didn't realize that I was include an external CSS which had set those attributes. Thanks!
