ABSTRACT:
A method for optimally controlling the carriage of a serial printer which is capable of printing line by line is disclosed. In controlling the carriage motor, until before the drive of the head, the carriage motor is controlled based on the head drive basic unit, i.e., steps of 1/360 inches, thereby making it possible to recognize the head fire position accurately. After the drive of the head, the carriage motor is controlled based on the carriage drive basic unit, i.e., steps of 1/120 inches, thereby reducing the number of interruptions in the central processing unit, and improving the system efficiency.
