4.1 Controlling Print Quality
The Printer provides maximum flexibility by offering both Direct-
Thermal and Thermal-Transfer Printing capabilities. To support
these printing options, the Printer has a flexible set of printing
controls.
The amount of heat applied to the Printhead, and the location of the
Printhead to the label media have the most effect on the images that
are printed on labels. The Printer provides print quality adjustments,
but limits them to prevent the Printer from printing an image that
could be damaging to the Printhead. For example, low cost direct-
thermal stocks have high reaction temperatures therefore it takes a
great deal of heat to make clear images on this type of paper. The
Printer has two ways to compensate for this; first set the burn time
to a higher value by using the H-Label Formatting Command. This
causes more heat to be transferred into the media, and consequently
generates a darker image. Second, adjust the Printhead position. The
Printer has been factory set to maintain good print quality on the
majority of media. However, when using media other than the
recommended 4 mil (.0004") thick stock the Printhead position,
ribbon, and media tracking may require slight adjustment to
maintain its print quality. If poor print quality is apparent, follow the
procedures outlined in sections 4.2.1 and 4.2.2.
