I wonder what was wrong with my previous answer ( to this same question. Why don't you tell?

I've looked a little bit deeper. Here on Windows XP MS Sans Serif is earmarked as a truetype font. But at home on Windows 95/98 it's not.

So please tell more on your OS and your font. If it is a truetype font, and still looks strange on paper, it probably is corrupted. The best thing to do then to do is to extact it again from your Windows CD. It depends on your OS how to do that.

And you don't tell either how the Print Preview looks on the screen. It should be the same as it is on paper.

Hope this helps.
