AFAIK, OpenOffice does multiple copies by multiply writing the same data
to the print job.

Besides that, it depends on the backend used for the printer. The IPP backend
is, I think, the only one that transferres job attributes to the printer.
The other backends seem to evaluate the copies attribute only for
raw queues (whenever they read from a real file, not from standard input).
