摘要： A printer comprising a printhead configured to selectively cause a mark to be created on a substrate. The printer comprises a stepper motor having an output shaft coupled to the printhead, the stepper motor being arranged to vary the position of the printhead relative to a printing surface against which printing is carried out, and to control the pressure exerted by the printhead on the printing surface. The printer further comprises a sensor configured to generate a signal indicative of an angular position of the output shaft of the stepper motor. The printer further comprises a controller arranged to generate control signals for the stepper motor so as to cause a predetermined torque to be generated by the stepper motor; said control signals being at least partially based upon an output of said sensor.
