1. Low voltage supply
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 batteriesor Ni-MH batteries can also be used. Two li-ion batteries can be used. 2. Low volume Compact and light
The mechanism is compact and light, dimensions: 68mm (width) * 24mm (depth) * 26mm(height). 3. Printing with High resolution
A high-density printer head of 8 dots/mm makes the printing clear and precise. 4. High speed printing
According to driving power and sensitivity of thermal paper, setting different printing speeds are required. Max printing speed is 70 mm/ sec. 5. Easy paper loading
Detachable rubber roller structure makes the paper loading easier. 6. Low noise
Thermal line dot printing is used to guarantee low-noise printing.
