When the print density level is increased, print speed may be reduced.
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.
