Review on 🖨️ 20ft USB Printer Cable, Ruaeoda Long Printer Cord USB 2.0 Type A Male to B Male Cable Compatible with HP, Canon, Epson, Lexmark, Dell, Xerox, Samsung, and More by Jamie Behm

I use this cable to control an electronic device with a USB B port (such as a printer). Since self-powered devices (such as printers) do not require a 5VDC 500mA power supply, this cable works great. DO NOT use long USB cables to power small external hard drives as they require 5V 500mA to operate. The DATA lines in the USB cable work great even over long distances (e.g. 30 or 50 feet). This is a very well shielded cable and perfect for my application (IC-7300 radio).
