it's funny you should post this just a few days ago... my girlfriend just ran into this problem today, and when i googled it, your post came up. we figured out the problem and fixed it easily by removing (or maybe in your case changing) the default printer. you can read more about it at microsoft.com at the link below. i'm only posting in case you haven't fixed it yet. good luck.
