The voltage used to drive the thermal printer head is equal to the logic voltage, or is driven by a 5 V single power line, the range of operating voltage is 4.2V-8.5V, so four to six NI-Cd batteries or Ni-MH batteries can also be used. Two li-ion batteries can be used.
The mechanism is compact and light, dimensions: 83.1mm (width) * 41mm (depth) * 39.5mm (height)
A high-density printer head of 8 dots/mm makes the good printing quality
According to driving power and sensitivity of thermal paper, set different printing speed required. Printing speed is 80 mm/ s(max.)
Detachable rubber roller structure makess the paper loading easier
Thermal line dot printing is used to guarantee low noise printing.
