3-inch thermal printer mechanism with platen latch function
Thermal printer mechanism TP31X series is ultra compact, high speed, light weight thermal printer, printing on 3-inch wide paper (80mm). This thermal printer mechanism, with easy loading mechanism, improves paper loading and printer mechanism maintainance greatly.
Unique Functions:
Optional design of double paper end sensors and optional sensor position, suitable for the printing of cash register with two small paper rolls.

1. With easy loading mechanism, to simplify and speed up paper roll replacing. 
2. Support label and thick paper printing.
3. High printing endurance up to 100km(recommend to use high quality thermal paper, such as F230AA Mitsubishi paper, DJ03 thermal paper)
