Adjusting the Print Contrast
You may need to adjust the print contrast if the printing is too light or too dark. Having
the correct print contrast is important because it affects how well your bar codes scan
and how long your printhead lasts.
Using a thin screwdriver, turn contrast knob clockwise for darker print; turn counter-
clockwise for lighter print.
__________
You only have to turn the contrast
adjuster slightly.
