INE LINES ENHANCEMENT
This feature can be used to emphasize the pen width of very fine
lines (minimum line width).
With some software applications, if this feature is turned ON, the
spaces in bar codes may become too narrow. If this happens,
turn [Adjust Ultra Fine Lines] OFF.
1. In the driver’s [Job Options] tab, click [Advanced].
2. Click the checkbox to turn on [Adjust Ultra Fine Lines].
If the option is turned on, a check mark appears in the box.
