ANUAL MODIFYING
(UP / DOWN
ARROW KEYS
)
When printer works in programming mode, that is it runs its main menu, it’s possible to modify the
printing intensity.
Printing intensity is expressed in percent and it can change into range 0% – 100%.
We cannot say there is an always good value for printing intensity; it is closely related to kinds of
media (labels, ink ribbon, etc…) one is using and it must be found by making practical tests of
printing.
Press UP arrow key to
increase
the printing intensity.
Press DOWN arrow key to
decrease
the printing intensity.
In both cases the message you’ll see is the next one:
Witty 2000ka
Head power: xx%
The shown percent (xx%) will change while you’ll keep button pressed.
Last value set will be kept into permanent memory even if printer will be turned off.

ODIFYING
If printer is connected to a PC, it’s possible to control the printing intensity by software command
?77&Percent
which must be sent via serial port to printer.
Parameter
Percent
expresses the percent of intensity to use.
Example:
?77&30
This command set printing intensity to 30%
Please refer to Programming manual for further datails.
WARNING: A too high printing intensity might reduce the lifetime of thermal print head.
