Thermal Printer Technology
Quiet and fast, with excellent print quality, your multifunction thermal printer
uses an inline thermal printhead. The thermal printer operates differently from
a line matrix or laser printer, because the thermal printer uses a printhead with
heating elements and special paper or ribbon.

The Printing Process
The thermal printhead allows two modes of operation:
•
Direct Thermal
During
direct thermal printing, the thermal printhead selectively heats
small, rectangular
thermal dots. When these contact the coated thermal
paper, the dyes and developers in the coating react to the heat and
develop an image. This mode of printing is generally used for short-term
labeling applications.

labeling applications.
•
Thermal Transfer
During thermal
transfer printing, the heated thermal dots contact a
thermal ribbon. The heat reacts with the ribbon and bonds the image to
the paper. This method is used especially for abrasive, long-storage
applications and for specialized applications, such as in extreme
environmental conditions or where tamper-proofing is required.
