How to use DI_APPBANDING ?

[Gert-Jan Vons]

[got no answer in microsoft.public.win32.programmer.gdi, maybe I've better
luck in this group?]

while reading the GDI docs I came across DI_APPBANDING (see DOCINFO),
described as "Applications that use banding should set this flag for
optimal performance during printing."

Unfortunately, that is all the documentation I found; does someone know
what this flag actually does and what an application is supposed to do with
it?

(I need to print some large (A0, D, E-size) bitmaps, and banding should
significantly reduce the memory requirements which is why I'm interested in
finding out more about this flag)
