If you want the printer to be connected to one of the computers in your network and then access it wirelessly from other computers using the router, start by installing the printer onto a computer that will be powered on whenever someone needs to print. No matter what version of Windows you are using, you will first need to physically connect the printer to both the computer and the power supply using the cables provided. Make sure both the printer and the computer are powered on. When you have completed this, it is time to install the printer onto the computer.
