Abstract
A printer has a print head on which a series of individually-heatable printing resistors are linearly arranged. The print head is mounted on a carriage for stepwise reciprocation in a direction parallel to the line of resistors, paper being stepwise movable in a transverse direction. The printing sequence is designed to permit the carriage stepping motor to be operating in the slew mode for maximizing print speed.
