I can't speak for Apple, but you shouldn't have to do this. You should have presented all of your UI between the Open and Close calls and synchronized with the job ticket and other panes during the Sync call, and you can do any work that doesn't require a UI during your Terminate call. If you find yourself having to intercept events intended for the Print dialog's Print button, you really should re-think your interface.

Basically, you really can't make any assumptions about what the Print dialog looks like or how it behaves outside the confines of the API. To do otherwise is to pretty much guarantee that you're going to break sometime in the future. I'm sure someone at Apple will tell you the same thing.
