How to get Quick Look to print PDF files double-sided? My default printer's default settings are to print double-sided. It works well in all apps, due to system-wide preferences… with the exception of Quick Look: when I open a file with Quick Look (pressing space bar in Finder), then ask it to print (Command-P), it does not open a dialog and send it directly to the printer, one-sided.

How can I configure this behavior? Or is there another shortcut to get the behavior I want?
If you are on Mountain Lion when u use quick-look and press Command-P to print the document. The "Quick-look App" actually opens the document in "Preview App" and make a simple print.
I advise you to open the document in preview directly to print it double-sided.
