There is a change in the width of the media.
Print width may be set by way of the five-flash sequence in
(see page 37) or refer to the Print Width (^PW) command (consult
your ZPL II Programming Guide).
Adjusting the Print Darkness
The relative darkness setting is controlled by either the six-flash sequence in
(see page 37) or the Set Darkness (~SD) command
(follow the instructions in the ZPL II Programming Guide).
Adjusting the Print Speed
Print quality is affected by print speed and the media you are using. Only
by experimenting will you find the optimal mix for your application.
If you find that the print speed needs to be adjusted, refer to the Print Rate
(^PR) command in the ZPL II Programming Guide.
