Priting from the Print Preview Page in Primavera P6 Professional

Every time I print a P6 activity table to a PDF file the individual activities fail to appear in the PDF file.

I initiate a print preview of a P6 activity table and everything appears as it should. However, when I then print the activity table to a PDF file, the PDF file displays the WBS categories but does not display the individual activities, as only blank spaces are shown where the activities should be.

In addition, printing from the P6 print preview window or directly from the P6 Activity window to either Microsoft OneNote / XPS Document Writer, or even an actual printer, produces the same effect. Individual activities fail to appear.
