Can I install a wireless Print Server on a network with a wireless router?

I recently purchased as wireless print server and am trying to install it on a network that already has a wireless router. Essentially, I have a main computer with 2 printers that is hooked up to a wireless router to allow access to another computer and 2 laptops nearby. I want the other computers to be able to print to either of the 2 printers. Am I wrong in purchasing a wireless print server? Do I just need a regular print server? When I try to install the new wireless print server, I get IP address conflicts. Anyone with suggestions?
