USB or Universal Serial Bus is the most popular interface for a printer or for that matter, any computer peripheral. Its popularity is largely due to its higher data transfer speeds and its ability to recognize new devices automatically.
The Universal Serial Bus provides a single, standardized, easy-to-use way to connect up to 127 devices to a computer. USB devices are hot-swappable meaning devices can be plugged into the bus and unplugged any time. Further, many USB devices can be put to sleep by the host computer when the computer enters a power-saving mode.
The newer USB devices support data speeds up to 480mbps (megabits per second).
