The disk I was referring to is the printer setup CD. You will need it to run the setup for the printer, and it's during that setup that you would connect the printer to the computer wirelessly.
Does your Toshiba laptop have a CD/DVD drive? The reason I ask is that some of the much smaller ones do not. If it does, pop the printer setup disk in and it should give you setup instructions. Make sure you choose to Direct Connect wirelessly when you get to the part where you can choose how to connect.
