The most likely explanation for this is that the client system is capturing
it before it even gets to the Web Browser.  Print Screen is fairly
universally captured by desktop operating systems, and each of them behave
slightly differently in what they do with that key combo.  Windows takes an
image and copies it to the clipboard.  Many Linux Window Managers bring up
a dialog with the image and ask you what you want to do.  Can't remember on
Mac.  The point is, if you want the Print Screen event passed through to
the browser, you need to configure the O/S not to intercept it (if
possible).
