by means of a thermistor in the print head. This will vary as the monitor prints and
with ambient temperature.
Strobe width is adjusted to regulate print density.
Stepper Motor Driver
, processes the information from the data bus and converts this
to a form acceptable to the stepper motor.
Stepper Motor
, drives the printer mechanism.
