Print density will be lighter when you select stronger improvement.
When printing from the computer, the setting in the printer driver takes precedence. When the setting
of [Graphics Mode] in the printer driver is changed to [UFR II Mode] and [Barcode Adjustment Mode] is
changed to [Printer Default], the setting in the operation panel takes precedence.
When you set [Barcode Adjustment Mode] to one of [Mode 1] to [Mode 3], [Special Print Adjustment A]
is automatically set to [Off].
