When I get a new computer it will be windows 7.?

Right now I am on XP. What I discovered my HP all in one C4480 printer,Olympus Master 2(for my digital camera FE-340),my logitech stx quick cam will not be compatible with the new windows 7. Do I have to give all this up to be recycled and spend more money to replace all this? Is there a way to make these work with windows 7?
