wherein:
the label roll support arm is configured as an elongated cylinder that permits the at least one label roll to freely rotate on the label roll support arm;
the elongated cylinder has an incomplete perimeter such that a portion of a circumference of the elongated cylinder is absent to create two opposing top free ends of the circumference and two opposing bottom free ends of the circumference, the top free ends having a first gap therebetween and the bottom free ends having a second gap therebetween; and
the inclined distal portion of the support bar passing through the notch passes through the first gap between the top free ends; and
