Media Selection 
The following is a limited overview of media characteristics. For complete information and 
advice regarding your specific application needs, always consult a qualified media specialist or 
a Datamax Media Representative. Also available is our informative whitepaper, "A Brief 
Introduction to Media," at  www.datamaxcorp.com. 
 
Media Selection – Direct Thermal  
 
Consider three important factors to consider when selecting direct thermal stock: 
 
•  The abrasive qualities of the material that covers the thermal reactive layer of the paper. 
 
•  The ability of that layer to control the chemical reaction that occurs when the image is 
“burned”. 
 
•  The amount of heat required to create an image on the paper. 
 
 
Media Selection – Thermal Transfer 
 
Consider three important factors to consider when selecting thermal 
transfer media combinations: 
 
•  The label top coating and ribbon combinations affect image quality. 
 
•  Ribbon backcoating is highly recommended. It provides protection for the printhead, and 
may also provide an anti-static coating. 
 
•  For additional printhead protection, use ribbon with a slightly greater width than the 
overall width of the label and backing material. 
 
 
Print Quality Controls 
 
The printer provides flexibility through comprehensive print controls. Of these, the amount of 
heat applied and the rate of media movement will have the most effect on the printed images. 
Five settings are available to control print quality; all are accessible via the menu system: 
 
Note: 
Heat and Speed values from the host software program may override the printer’s 
menu setting; see Host Settings.  
 
•  The first setting is MEDIA SETTINGS / MEDIA TYPE -- select the setting that matches 
the media being used.
