ABSTRACT:
In a serial printer, a thermal printing head is mounted on a printing head holder which in turn is mounted for movement across the width of the paper and wherein a spring force is utilized to press the printing head onto the paper; a lever mounted on a lever pin is connnected to the printing head and the lever cooperates with two cam elements and a cam surface located at selected points of travel of the printing head whereby the printing head will be removed from or engaged with the paper when it reaches a limit of travel and will remain out of contact with the paper while the paper is advanced to the next printing position.
