AFAIK there is not an API for doing that, see also

What I would do in this case is to hack a bit QPrinter sources
and exposing QPrinterPrivate::setPreviewMode, then printing normally, and then
retrieve a list of QPictures with QPrinterPrivate::previewPages
(see what QPrintPreviewDialog does).

Since QPicture is a QPaintDevice,
you can paint over them (and add headers/footers) with a QPainter.

Then you can disable the preview mode and print the modified QPictures.
