HP 5110 All-In-One printer / Vista problems

Question

I have an HP 5110 all-in-one Series printer and a new HP desktop computer which has Windows Vista. When I try to connect the printer it does not work. I went to the HP website and it says that my printer is not compatible with Vista. Is there anything that I can do short of buying another printer. Is there a way to downgrade back to the XP OS that I was using with my older desktop?
