Control signal
Data on the computer which is created in the printer driver is divided into the control command
and the print data in the printer ASIC. The control command is sent to printer control ROM
and each sensor from ASIC through MPU. According to the program in the control ROM
(Flash ROM), the signal which controls the motor or head is output from the ASIC.
