• Cash registers • EFT POS terminals • Portable terminals • Measuring devices • Medical equipment • Taxi meters • Weighing scales• Low voltage supplyThe 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 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.• Compact and lightweight designThe mechanism is compact and light, dimensions: 45.2mm (width) * 32.7mm (depth) * 15.1mm (height)• Printing with high resolutionA high-density printer head of 8 dots/mm makes the good printing quality• High speed printingAccording to driving power and sensitivity of thermal paper, set different printing speed required. Printing speed is 80 mm/ s (max.)• Easy paper loadingDetachable rubber roller structure makess the paper loading easier• Low noiseThermal line dot printing is used to guarantee low noise printing.
