You don't need wireless in order to print to a wireless printer.
I'm imagining you connect to the internet through a router? If so, all you do is connect the printer to the network (wirelessly) then set up the printer on your computer. It wirelessly connects to the network is what that technology refers to.
I'll expand on this a bit.
My laptop connects to the router wirelessly. My pc connects to the router via ethernet.
I had no problem printing through the router with the laptop but can't get the pc to do it!!
