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?
