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.
