Chapter 3 Advanced Usage Print speed Selectable from levels 1 to 10 (Slow ~ Fast) (initial setting: level 10) Depending on print conditions, such as print duty, print head temperature, and data transmission speed, print speed is automatically adjusted, which may cause white lines due to intermittent print (the motor sometimes stops). To avoid this, keep the print speed constant by setting it lower.
