Abstract: An electrode drive configuration for a resistive ribbon (12) thermal printer utilizes as a feedback a monitored signal representative of an internal ribbon voltage at the print point. A monitoring contact (50) is preferably located on the opposite side of the printhead from the drive signal return contact (28) and the feedback signal is used to cancel the effects voltage drop variations in the common return portion of the drive signal path.
