Communicating with the Printer
When using the parallel port, typically there is no setup is required once the
cable is plugged in. If you should encounter any problems, consult the
user’s guide that came with your computer.
Adjusting the Print Width
Print width must be calibrated when:
■ You are using the printer for the first time.
■ There is a change in the width of the media.
Print width may be set by way of the five-flash sequence in “Feed Button
Modes” (see page52) 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
“Feed Button Modes” (see page 52) or the Set Darkness (~SD) ZPL II
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.
