In QT perhaps, in KPrinter too, but not in KOffice. In KWord's Format/Page, 
you cannot select it.

No, no, it is not a matching failure. It is a non-supported feature in 
KOffice.

(As for QPrinter's richness, well, it misses many ISO C formats, which means 
that you miss a whole range of envelope formats.)
