ABSTRACT:
Printing data are memorized temporarily in a printing data memory unit 40 and then read out for printing on a printing medium 6, which is being transported by a pulse motor 10 first in a forward direction (this state is called "normal operation state"); and when all the data in the printing data memory unit 40 have been read out, the CPU 31 makes the motor control unit 32 shift to a "stand-by state", wherein by an operation pattern of the pulse motor 10 memorized in RAM 33 the pulse motor 10 transports the printing medium 6 at equal short lengths forward and backward at a lower speed than in the normal operation state; and thereafter the printing medium is transported at the same speed as that in the normal operation state; a smooth continuous printing with a memory of a relatively small capacity is performed.
