Key Features :
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 batteries or Ni-MH batteries can also be used. Two li-ion batteries can be used. 2. Compact and lightweight design The mechanism is compact and light, dimensions: 69.7mm (width) * 32.7mm (depth) * 15.5mm (height) 3. Printing with high resolution A high-density printer head of 8 dots/mm makes the good printing quality 4. High speed printing According to driving power and sensitivity of thermal paper, set different printing speed required. Printing speed is 70 mm/ s(max.) 5. Easy paper loading Detachable rubber roller structure makess the paper loading easier 6. Low noise Thermal line dot printing is used to guarantee low noise printing.
