Introduction
The Thermal Printer Mechanism for APS Printer are very compact and easy to integrate into your design. Secondly, the rigid die-casting frame in our products allows better thermal conductivity. Finally, it is suitable for industrial environments such as weight, control, security systems, and medical and portable applications.
Feature
The Thermal Printer Mechanism for APS Printer have integrated powerful controller boards. Secondly, thanks to the innovative linear gear train, this makes our operation very quiet and the print quality is very high. What's more unexpected is that our products also have powerful dual stepper motors. Finally, our extremely straight paper path allows thick paper or label printing.
