Hp psc 1350v all-in-one printer won't work?

I have windows vista on my laptop, and the last time i plugged it into my laptop my printer worked. But suddenly now it won't work. I've looked at the hp help site and it told me to just plug it in and it would automatically install. But vista isn't recognizing it as a printer, it thinks it's a disk drive. I've tried plugging it into all 3 of my different USB ports and nothing works.
