USB Type A plug(male) to USB Type B plug(male) cable.
Probably the most common use for these cables is to connect a USB printer to your computer.
Good quality cable. USB2 for faster data transfer.

All printers with USB sockets I've seen use a 'B' type socket, which matches the plug on this cable.
It seems the printer companies are cheap, as the USB cables never seem to be included when you buy a printer!

A is the wider USB plug, which is the standard type used for plugging into a computer. B is the squarer plug, used to connect to printers etc.
--> See photo - there is enlarged, labelled pictures of both plugs.

Possible devices that would use this cable(please check manual/specifications for your product first) :
printer
scanner
camera
external hard drive
webcam
& probably a number of other devices

Cable length: 2 metres
