What is the square connection on the end of a usb printer lead called? -

Hi on a usb printer lead there s the rectangular end that connects to the pcs usb port and the square end that connects to the printer. Can anyone tell me what the square end connection-type is called?

The flat one is a USB type quot;Aquot; and the square one is a USB type quot;Bquot; from what I just learned. http://www.xiertekusa.com/product.php?pi…
