Thank you to all who answered this ?, I hope this helps some others.
I was having a problem with Civil 3d 2011 DWG to PDF print function. The preview image would look fine, but the actual PDF had problems. The PDF did not print many of my labels properly. Fortunately for me, the discussion group had already handled this problem. Below is a step by step supplement to the existing resources.

3. Under "DEVICE AND DOCUMENT SETTINGS" tab, select "CUSTOM PROPERTIES"
4. Click "CUSTOM PROPERTIES" button below
