Repeat the steps in the same way. Transfer the data which will be printed in the next step to the
thermal head while starting the activation of the thermal head.
The data transfer time and head activation time may be longer than the motor step time according to
the type of the thermal paper, printing data and operational environment.
In this case, hold the motor step until completion of printing.
Keep 0.1 msec or more for the pause time after head activation.
The print data in the First step can be transferred while outputting the Start step (B). However, the
print data is transferred before outputting the Start step in Figure 5-1.
