The USB (Universal Serial Bus) cable is the industry standard for connecting hardware devices. It was designed specifically to handle communications between computers and their peripherals, such as: keyboards, printers, disc drives, and pointing devices. The USB cable now extends beyond home computers to the POS industry, quickly becoming the preferred interface for barcode scanners, receipt printers, barcode printers, card printers, magnetic stripe readers, customer pole displays and more.
Cables are available in many sizes and colors — for most equipment, a six-foot cable is more than sufficient. When purchasing your cable, be aware that USB features a few different connections; the main ones are the A plug (Male) and the B plug (Female). Check your hardware to see which end types you need before purchasing.
