Abstract
Abstract A carriage assembly for an impactless printer having a printing head mounted for reciprocal movement across the paper to be printed. A cable is attached at either end and passes around a drive pulley at one side of the printer and an idler pulley at the other side. A bi-directional motor drives the pulley. A solenoid rotates the mounting means for the head so as to move the stylii into and out of contact with the paper.
