So it is no on your wifi network. I'd suggest you look up the support docs for that printer on Samsung's web site and go through the steps there to get it on your wifi network. Once it is, it should be a simple matter to add that network printer to your Mac via control panel.
I've never used a Samsung printer, which is why I say you should check their docs (they must have a step by step guide for connecting to your wireless network). On most machines with a built in display, it is much like any other wifi device - go in, enter or select teh SSID, enter your WPA2 password or whatever encryption key you use andoff you go. Unless your router is using MAC address filtering, in which case you'd need to go into the router's admin page and add the printers MAC address.
