Depending on print conditions, such as print duty, print head temperature, and data
transmission speed, print speed is automatically adjusted, which can cause white lines due
to intermittent print (the motor sometimes stops). To avoid this, set the transmission speed
higher or keep the print speed constant by setting it lower. (See
"Setting the Memory
Switches" on page 45 .)
