I've noticed that in a couple/few instances, if you select Email as the method of Printing, after the email is sent it goes back to the Print dialog. That's kind of neat, but with it not being consistent across all documents it's kind of a pain because you can end up with extra forms around, forgetting that you've first printed it and then emailed it. I much prefer to either Preview (and print from there) or Print before emailing to ensure that everything looks ok, rather than emailing and then realizing I made some stupid mistake...
What I'd REALLY like is check boxes instead of radio buttons for the Print Types. Saveable as a User Setting, of course!
