Stats of pages printed with browser

Just curious here...

I'm wondering if there is a way that I can track the pages printed via the browser (File -> Print).

I know of several ways to track pages printed otherwise, either via a print stylesheet, or via javascript or php that would be invoked through a physical "print page" button in the markup. It's pages printed through the browser that I'd like to track.

Essentially I'd like to be able to track the performance of individual pages printed, in a dynamic setting.

Anyone have any ideas on this one?

Thanks,
