How to Dell 1135n Network Printer setup?

Hello every one: Question?

How can I setup the Dell 1135n Multifunction Mono Laser Printer on a wired network setting? Currently it is connected with an USB cable as a local printer. I have to switch the cable between two laptops and one desktop computer to print. I have connected it to the router with a CAT 5e cable. Need guidance to setup the network connection. Thank you.
