A:Answer Blue Tooth is a protocol between two devices, like a mouse and a computer or a computer and speakers or a cell phone and speakers. When the two devices are locked-in together, they are called "paired."
WiFi is a network that is usually present in a home, a business, a sporting stadium, or a Starbucks. The network lets multiple devices interact with each other and, especially, the Internet. W WiFi network typically has a wire from outside connected to a modem and the modem in turn is connected to a router. The router(s) propagates the WiFi radio signals that allow your devices to communicate with each other.
I suspect what you want is a WiFi printer, but you need a WiFi network in your environment (home) for the WiFi feature to work. If you access the Internet wirelessly in your home, I suspect you have such a network in place. If so, the network will have a password that you will need to bring the printer into the network when you set it up.
