What is the difference between direct thermal and thermal transfer technology?
热敏与热转印技术的区别是什么？
Direct thermal technology uses a thermal print head to heat thermal reactive paper creating black marks. Thermal transfer that uses the same type of thermal print head but instead of heating the paper directly, it heats an inked ribbon. The ink on the ribbon is a wax based and when it is heated, will transfer to the paper pressed against it. The APR430 and APR530 are thermal transfer printers that are reconfigurable as direct thermal based on the application. The APR331 is a direct thermal printer and requires direct thermal paper.
热敏技术利用热敏打印头加热热敏纸，从而产生黑色标记。热转印技术使用相同类型的热敏打印头，但不是直接加热纸张，而是加热色带。色带上的墨水为蜡质墨水，当受热时，会转移到压在其上方的纸上。APR430与APR530为可根据应用需求，通过设置可以具备热转印或热敏打印功能APR331为热敏打印机，需要使用热敏纸。
