Adjusting the Print Width
Print width must be set when:
• You are using the printer for the first time.
• There is a change in media width.
Print width may be set by:
• The Windows printer driver or application software such as Zebra Designer.
• The five-flash sequence in Feed Button Modes on page 87.
• Controlling printer operations with ZPL programming; refer to the Print Width (^PW)
command (consult your ZPL Programming Guide).
• Controlling printer operations with EPL Page Mode programming, refer to the Set Label
Width (
q) command (consult your EPL Programmer’s Guide).
Adjusting the Print Quality
Print quality is influenced by the heat or density (setting) of the printhead, the print speed, and
the type of media you are using. Only by experimenting will you find the optimal mix for your
application.
The relative darkness (or density) setting can be controlled by:
• The six-flash sequence in Feed Button Modes on page 87. This will overwrite any ZPL
and EPL programmed darkness/density settings.
• The Set Darkness (
~SD) ZPL command (consult your ZPL Programming Guide).
• The Density (D) EPL command (consult your EPL Programmer’s Guide).
If you find that the print speed needs to be adjusted, use:
• The Windows printer driver or application software such as Zebra Designer.
• The Print Rate (^PR) command (consult your ZPL Programming Guide).
• The Speed Select (
S) command (consult your EPL Programmer’s Guide).
Note • Media manufactures may have specific recommendations for speed settings for your
printer and the media. Some media types have lower maximum speeds than your printer’s
maximum speed.
