Cups output only text, no graphics

Hi,
I have problems with the output of virtual printer on Ubuntu. Installed cups-pdf and manually added virtual printer via browser interface. Printer is recognized by Wine.
Made a Gantt Chart with MS Project 2007 (need to do it) under Wine. Print Preview correct, but printed pdf shows only text, timeline graphics and legend wouldn't show. Later tried with MS Project 2003, virtual printer on Xubuntu. Same problem.
Is it possible to enable/disable graphics output in virtual printer? Or what could the problem be?

Thanks, kl
