The PPD file is, at any rate.

I couldn't find anywhere anything about nup printing or the number of copies. is this really handled at the driver level, or is it handled at the CUPS level. Can the driver fix those bugs ?

What I suspect is happening is that there's a problem with the PPD
file whereby it's telling CUPS that CUPS itself has to handle multiple
copies (so CUPS sends multiple copies to the printer) while also
passing through the command to generate multiple copies (that would
explain why when you ask for 2 copies you get 4, and when you ask for
3 you get 9).

Could you reply attaching the actual PPD file you're using (not simply
the one that was downloaded) so we could take a look at it?
