Not printing two sided anymore

[Kimberly]

I have a two page portrait presentation that I was printing two sided
(duplexed). For some reason it will no longer print two sided, although my
print settings have not changed. I tried a new presentation (several) and it
works, but the current one won't anymore.

All the settings are the same, this is the only one that won't print two
sided when it used to.

Anyone have any ideas why.

Thanks.

Duplex is a printer setting and not influenced by PowerPoint. (What you see
in the PowerPoint Print dialogue are the Printer driver settings mirrored
there from the operating system.) Did you change anything with your printer?
Is one of the slides marked as hidden? If new presentations print correct,
then copy the contents of the presentation into a new one based on the same
template (copy the objects, not whole slides).
