ABSTRACT:
A tape printing device comprises a print head, means for causing relative movement between an image receiving tape and the print head, and control circuitry for controlling the print head. The print head has a set of selectively activable printing elements arranged along a longitudinal axis of the print head. The control circuitry prints each pixel by activating the same printing elements on successive print cycles to limit the peak current of the print head. Each group of printing elements lie at an acute angle with respect to a longitudinal axis of the print head to prevent staggering in the printed image. The tape printing device uses an arrangement of group switches and switches for individual printing elements to reduce the required number of switches which reduces the cost of the apparatus. Current is controlled to prevent accidental activation of printing elements to reduce the number of errors in the printed image.
