Qt print dialog severely lacking functionality

As it stands the printing support in most Qt application is pretty awful, as the standard Qt5 printing dialog is very basic and limited (this was in fact better in Qt4). This is quite an issue, since proper print support will be something that is expected of an application in pretty much any situation.

I think the most critical missing option would be the control over scale and positioning (printing in a qt application will always center and scale to page dimensions), as this can really mess certain things up.

But of course, there’s a lot of other thing missing in the  Qt5 print dialog that would be considered more or less a dealbreaker in most office situations, like booklet printing, or printing some oversized content on multiple pages, printing n-up (i.e. multiple pages on one page), a print preview, &c.

So I think at least some priority should be put to reworking the printing dialog.
