PRinter on wireless network

I have a USB printer on my current machine with a wireless router. I will be building a new system within the next week and the new mobo has built in wifi. I know nothing about networking and my wife's work computer (a laptop) has a network card so she can access the internet, but that is the extent of what we do.

Now, if I do not have the printer hooked up to the new machine and keep it hooked up to my current machine, where do I find instructions on how to set it up for sharing the printer wirelessly?

The router is a Linksys wrt54g.

Thanks!!

After posting I read some more and think I need a wireless print server. The router I have is (I think) just for internet, since the printer is plugged into the computer and NOT the router.

I do want to share the printer. I just don't know how to do it. I would want wireless but don't want to spend a lot of money. I originally thought that I could use my new computer's built in wireless (It's the asus p5w dh) to "talk" to the printer without having to do anything since my current machine has the Linksys router. Like I said I think I need a print server, but you tell me as I really do not know anything about this.
