How to connect to my wireless printer for dummies?

It depends on the printers brand as there are a broad range of wireless printers offering all sorts of connections.

Generally speaking, you would want the printer to connect to the network (LAN) this could be done on the printer. Refer to the printer's manual. I think you can also connect it via the computer. Just find it on the computer on 'find printer' in your computers settings. Specify the printers name in order to this.
