Characters are printed by energizing the respective print solenoids at the timing corresponding
to the head carriage movement position, using the carriage motor phase change signal as a
reference signal. The print head unit is moved approximately 0.339 mm by a one step rotation
(7.5°) of the carriage motor.
To print the number "2", printing solenoid numbers 2 and 9 are energized in sync with the
carriage motor phase change signal. Next, print solenoid number 8 is energized in sync with
TnH, delayed by a half dot time interval. The number "2" is printed by repeating this process.
