Print Operations
Darkness Control
The Darkness Control switch allows the operator to modify the darkness setting for minor
variations in media and printers avoiding the need to change the program or driver settings
sent to the printer.
The control switch has three (3) settings:
• Left (Low - Default): no effect .
• Middle (Medium): increases ZPL darkness 3 levels.
• Right (High): increases ZPL darkness 6 levels.
The Low (default) setting makes no change to the actual Darkness setting as set by
programming or driver setting. The Medium setting increases the Darkness level by 3, i.e.
if the printer is set to the default darkness level of 20, then the actual darkness applied
while printing will be 23. The High setting will add six (6) darkness levels to the set
darkness level.
Important • Setting the Darkness too high or too low may reduce barcode readability.
