How do I print multiple double sided presentations?

[Karena]

I need to print multiple copies of a presentation (Handouts: 3 slides per
page, double sided). My problem is that when I set the # of copies and click
the duplex box for double sided my presentation has a total of 9 pages. When
the first copy finishes printing, the second copy starts printing on the
second side of the last sheet in the first copy.

Is there a way I can correct this?

Add a blank slide or two to force it to be 10 pages?

This actually sounds like an issue with the printer driver. Is there a place
in printer properties (File|Print|Properties) to specify that each printout
begin on an odd-numbered page?
