Problem Printing Gantt Charts

I seem to be able to print everything except Gantt charts. When I select the print icon or File>Print for the "Tasks and Milestones > Gantt View" page and attempt to print, I get a blank document. I've also tried saving as a pdf with the same result.

This is a useful presentation tool and I'd like to be able to print or, even better, create a pdf that can be emailed around to team members.

What am I missing?
