thumbwheels as required to maximize the clarity and detail of the label.

the printhead, and lighten the image. Turn thumbwheels clockwise to
lower them, increase pressure on the selected printhead, and darken the
image.

5 Flip the printhead cam closed to restore pressure to the printhead.

other settings that affect print quality, such as heat intensity.
