Scenario 4: Computer connected wirelessly to a printer without Internet access

•A computer is directly connected to a printer without going through a wireless router.

•This configuration is referred to as an ad hoc network.

•The network has no connection to the Internet.

Note: Most computers can connect to only one wireless network at a time. If you access the Internet over a wireless connection, you will lose Internet access if you are connected to an ad hoc network.

What is a USB cable?

A Universal Serial Bus (USB) cable is primarily used to connect a USB device to a host. Common hosts include computers and video game consoles. Through the USB port and cable, it is possible to connect computer peripherals such as mouse devices, keyboards, digital cameras, printers, personal media players, flash drives, and external hard drives. For many of those devices, USB has become the standard connection method.

Why do I need a USB cable?

When setting up the printer on your wireless network, the printer will need to temporarily connect to a computer using the USB cable. This temporary connection may be used to set up the wireless settings of the printer.

Note: A USB cable is not necessary when connecting to a wireless network through Wi‑Fi Protected Setup (WPS).

How do I attach the USB cable?

The USB cable attaches to a USB port on the computer and to the square connector on the back of the printer. This connection allows you to configure the printer for a network or local (USB) installation.

The USB port on the computer and on the printer are each marked with .

Note: Do not connect the USB cable until prompted to do.
