ABSTRACT:
In a printing apparatus, after the initial process program, printing data input from a host computer is stored in the receiving buffer of the control system of the printing apparatus. Then, a determination process program detects control codes from the printing data stored in the receiving buffer. One operation mode for printing is determined based on the detected control code. As a result of the determination process program, if a plurality of operation modes are determined or if no operation mode is determined, the determination process program uses operation mode historical information stored in an operation mode historical information buffer to determine one operation mode candidate. Therefore, the degree of certainty is high in automatically determining an operation mode which best corresponds to the printing data, and the chance of a misjudgment of an operation mode is extremely decreased.
