Review on StarTech.com 3ft (0.91m) Right Angle USB Cable - 1x USB A to 1x USB B - Black (USB2HAB2RA3) by Robert Cooper

Sometimes you have a printer or modem that you want to put on a shelf or against a wall, and the USB cable gets in the way of your neat installation plans. They have a rectangular USB Type-A connector on one end and a rectangular USB Type-B connector on the other end. This is a standard USB printer cable but with square plugs. Both cast end caps. So you can now place the printer directly against the wall without damaging or damaging the USB port.
