For current stable gnome-print, you have to use
But this has real mening only for preview. For PS you can print wherever
you want - actual output is simply clipped to printer margins.
In HEAD gnome-print, there will be a way to query/set actual paper size
plus query physical margins - but it still remains the application
responsinbility to set logical margins and fit all printout inside

Well, depending on application, you probably want to manage certain set
of paper data youself nevertheless.
Gnome-print will only deal with physical page sizes - i.e. the ones,
what printer actually supports. There is mechanism in HEAD to merge
application and printer pages - i.e. if you select A4 from printer
setup, application get notified and vice versa. Still there certainly
are cases where application wants to ignore printer page size - like
Also gnome-print is not interested in logical margins, headers, footers
and so on.
But it would be certainly good idea, to create standard widget set for
such things - either in gnome-print frontend API, gal or gnome-libs.
Together with actual text formatting API (gnome-print core
should not do any text-layouting itself). I am not working on anything
like that, but if nobody volunteers, I have to start with text part
myself some time, to make gnome-print usable in Pangoified world.
