How can document scaling be suppressed? (MS Power Point 2007, Vista)

I am running pdf-creator V 0.9.5 and I have the following problem when printing an A4 landscape slide from MS Power Point 2007 (Vista):
The pdf gets somehow scaled, and printing starts 7 mm shifted to the right. When I print the same slide to my printer, it looks perfect. What am I missing?
