I have started using Cambria font in all my MS Word 2007 documents. When I try print the documents to pdf using the Acrobat plug-in, I am unable to do. Problem seems to be caused by an incompatibility with Cambria font.
[Answer]: When you are in the print dialogue, and you have selected the appropriate PDF printer, select “Properties.” In the dialogue box, there should be a tab titled “Adobe PDF Settings”. You need to un-check “Rely on system fonts only; do not use document fonts.”
