•
The print speed changes automatically depending on the applied voltage and head
temperature.
•
If the data transmission speed is slower than the maximum print speed, the print speed may
fluctuate and the print result may become shaded and/or dot displacement in paper feeding
may occur. Furthermore, if the data transmission speed is much slower than the maximum print
speed, intermittent printing will occur.
