|If the printer is in the same room as your computer, you can plug the printer into the computer using a USB cable. If it's not in the same room, read the next paragraph.|
Your printer is not wireless so you will need to get an Ethernet connection in there somehow. The easiest way would be to use a technology called IP over AC. Basically you have two devices, one sender, one receiver. The sending unit has an Ethernet port which connects to the router and plugs into the AC outlet. The receiver also has an Ethernet connection, you would plug the receiver into the AC outlet in the same room as the printer and plug the printer into the receiver.
Most companies that make routers also make these devices and can be found at electronic stores like Best Buy.
