What type of connection uses network cables to connect to a printer's RJ45 port?

A wired Ethernet connection utilizes network cables to establish a physical link to a printer equipped with an RJ45 port. This type of connection is common in office environments where printers are shared across multiple computers or devices. By connecting via Ethernet, the printer can be part of a local area network (LAN), allowing multiple users to send print jobs over the network without needing direct physical access to the device.

The RJ45 port is specifically designed for Ethernet connections, which facilitate high-speed data transmission. This configuration ensures that users can easily manage and send print tasks from various devices within the same network environment, enhancing efficiency and providing reliable connectivity.

In contrast, options like USB connections use different ports and cables for direct, point-to-point connections, while wireless connectivity and Bluetooth connections rely on radio signals rather than physical cables, which makes them unsuitable for linking to a printer through an RJ45 port.
