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-9.5V, so this PT48G thermal printer mechanism can be driven by four to six pcs of NI-Cd batteries or Ni-MH batteries, or two pcs of Li-ion batteries.
The mechanism is compact and light, dimensions: (69.3)mm (width) * (46.0)mm (depth) * (19.0)mm (height).
A high-density printer head of 8 dots/mm makes the good printing quality
According to driving power and sensitivity of thermal paper, you can set different required printing speeds. And PT48G thermal printer mechanism printing speed is 100 mm/ s (max.)
Detachable rubber roller structure makess the paper loading easier
Thermal line dot printing is used to guarantee low noise printing.
