Missing Print Options in Office and PowerPoint 2011
I just solved this on my own machine. Very frustrating.

The issue is that the missing section of the print dialog is a "Print Dialog Extension" (PDE). This is loaded from the individual Office apps' plugin directories. The issue is that Office is coded to look for a "PlugIns" directory whereas the directory is actually named "Plugins".

I suggest using a symbolic link to fix this. Presuming you have a default installation of Office then open Terminal, and execute: 

cd "/Applications/Microsoft Office 2011/Microsoft PowerPoint.app/Contents/"
ln -s Plugins PlugIns


Relaunch Powerpoint and bask in the delicious print dialog extensions. BTW, you will need to do something similar for the other Office apps.

NOTE: I advise against simply renaming the Plugins directory to PlugIns. It might break something else.
