5.1Controlling 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 printed on the 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 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 5.3 and 5.5.
