Bought new computer with windows vista, my printer [deskjet f380] is not compatable with vista,any thing i can do,or will i need a new one.

Hi! Windows sometimes offer a compatability issue report and should direct you to the site where Vista related drivers can be installed, if not try Hp's website support/downloads for Vista compatability issues. I'm sure if the printer isn't too old then your luck may be in and you'll get the required driver/s.
I hope this helps!
