3 inch Thermal Printer Mechanisms


    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: 93mm (width) * 34.5mm (depth) * 39.5mm (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 85 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.
