Unfortunately there is no common api to do these on all platforms.

N-up is supported by Cups so on Linux it can be added to the dialog, and it is 
already in the OSX dialog, but I'm not sure if there is a need for QPrinter 
api to set if for dialog-less printing?  Windows has no native support, so Qt 
would have to implement it.

Booklet printing is not supported by Cups, and talking to the guys at Apple it 
is unlikely to be supported, they are just not interested, so Qt would have to 
implement that as well.

These and other advanced page manipulations could be done in QPainter, I know 
it has been suggested that the QPrintPreview could be made to do this fairly 
easily, but that would be a phase-2 thing. I want to get the common printing 
api's done first, it's a pain-point that can't be worked around.
