Abstract

A printer with a single motor system to match torques between ribbon supply and ribbon take-up is provided. The printer comprises a ribbon supply spindle, a take-up ribbon spindle, sensors to output ribbon width and diameter at ribbon supply, and a sensor which outputs ribbon diameter at ribbon take-up. The printer is provided with a drive system providing rotation to the ribbon supply via tension on the ribbon loaded on the ribbon supply spindle and taken-up on the take-up ribbon spindle. Firmware, communicatively linked to the sensors and the drive system, is configured to calculate ribbon tension at the ribbon supply spindle, to calculate the torque required on the ribbon on the ribbon take-up spindle to match the ribbon tension at the take-up spindle to the ribbon tension at the ribbon supply spindle, and to adjust the drive system to match these torques.
