PRODUCT OVERVIEW
Product Introduction
Low noise, sturdy and durable, high-speed printing 90 mm/sec (8.5V), easy paper loading structure, 90-degree vertical paper feed
Low-voltage power supply
The logic voltage for driving the thermal head is 2.7~5.5V and the heating operation voltage is 4.2~8.5V; it can be powered by 4 to 6 NiCd or Ni-MH batteries, or by two lithium batteries.
Compact size
Small external dimensions, convenient for portable applications. Dimensions: 69.2 mm (W) × 28.3 mm (D) × 31.7 mm (H).
High-definition printing
High-density print head, 8 dots/mm, delivering more precise and clearer results than dot-matrix printing.
Fast printing speed
Different printing speeds can be set according to customer requirements, depending on the driving energy and the thermal sensitivity of the thermal paper used; up to 90 mm/sec.
Easy paper loading structure
The detachable rubber roller (platen) design makes paper loading simple.
Low noise
Compared with dot-matrix printing, thermal printing is more suitable for environments with noise restrictions.
