Can someone help me find the drivers for a Benq SZW 4300u scanner?

I have looked and looked all over the internet (it is a school project, so there are a few of us doing it and we can't find it) and can't find the drivers so if anyone can help it would be great.
Update: it is for vista but if it comes with a linked to xp and ubuntu (and maybe apple as well) it would be great
