2.1.05 Print Control

The print data is transmitted as serial data from the LSI to the control circuit and the driver
contained in the printhead.
After the data is printed, the sensor analog circuit controlling each pin returns the pin stroke data
to the MPU. The MPU will make an automatic head gap adjustment. This feedback system sets
the optimum drive time for each pin in order to maintain high print quality.
