Thermal Printer Technology

Quiet and fast, with excellent resolution output, the T3306 and T3308 are multifunction printers using an inline thermal printhead. The operation of a thermal printer is different from that of a line-matrix or laser printer. 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

•Thermal Transfer

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.

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.

Dynamic Print Control

The thermal printer has a unique feature that provides excellent print quality by preventing unevenness of print density. Unevenness is usually caused by the stored heat from previous dots. Print quality largely depends on how the thermal paper or the thermal ribbon and thermal transfer paper responds to the heat of the thermal printhead.

During printing, the thermal printhead must reach a set temperature in the shortest possible time. Then it must cool down to the original temperature in the shortest possible time after printing. Thus print quality is dependent on the precise control of the energy supplied to the thermal dots.

The Dynamic Print Control is a history control whose output is based on the results of the previous printing. The printer predicts the quantity of heat required to print dots and regulates the electrical energy applied to the printhead. This prevents unevenness of print density and results in the printing of narrow-ladder bar codes or vertical grid lines that are straight from the microscopic viewpoint.
