CONFIGURING PRINTER
ADJUSTING THE PRINT WIDTH
ADJUSTING PRINT QUALITY
Print width must be set when:
Print quality is influenced by the heat or density setting
of the printhead, the print speed, and the type of media
in use. Experiment with different settings to find optimal
mix for application.
• The printer is being used for the first time.
• There is a change in media width.
Print width may be set by:
Relative darkness (or density) setting can be controlled by:
• Windows printer driver or application software such
as Zebra Designer.
• Controlling printer operations with ZPL programming;
refer to the print width (^PW) command.
• Controlling printer operations with EPL Page Mode
programming; refer to the Set Label Width (q)
command.
• The Set Darkness (~SD) ZPL command.
• The Density (D) EPL command.
To adjust printer speed use:
• Windows printer driver or application such as Zebra
Designer.
• The Print Rate (^PR) command.
• The Speed Select (S) command.
PRINTING A TEST LABEL
NOTE: Before you connect the printer to your
computer, make sure the printer is in proper
working order.
Figure 6

CLEANING PRINTER
NOTE: Adhesives and media material over
time can transfer onto the printer components,
including the platen and printhead. This
build-up can accumulate dust and debris.
Failure to clean the printhead, media path
and platen roller could result in inadvertent loss
of labels, label jams and damage.
NOTE: Using too much alcohol can result in
contamination of the electronic components
requiring a longer drying time before the
printer will function properly.
When cleaning the printer, use one of the following
