7.3 Approved Media and Ribbon
Media (and ribbon for thermal transfer) is an important determinant in the throughput,
quality, and performance of the printed product. The following overview is an introduction to
the different types of material that can be used in the printer. For complete information and
advice regarding a specific application, consult a qualified media specialist or a Datamax
Media Representative. Also available is an informative white paper, "A Brief Introduction to
Media," which can be found on our website at www.datamaxcorp.com
Direct Thermal
Consider three important factors when selecting direct thermal stock:
• The abrasive qualities of the material that covers the thermal reactive layer of the
paper;
• The amount of heat required to start the chemical reaction; and,
• The ability of the media to control that chemical reaction.
