Introduced by NADA ELECTRONICS, AS-289R2 Thermal Printer Shield is the most advanced two-inch (58 mm) thermal printer in the industry.

You can directly connect the thermal printer to your Arduino, ARM mbed, Raspberry Pi, and Gadget Renesas.

Its print speed is 25 mm/sec and effective printing area is 48 mm.　The printer is also suitable for printing various types of bar code.

For printing, it takes more power than what USB can provide. Please use the harness included and connect the printer to AC adapter for power supply (above 5 V 3 A). The alternative way to supply power is by using the jumper pin on the printer, and you can provide 5 V from the printer to Arduino.

To find out how to change the thermal paper roll paper, run test printing, and to use HEX dump mode, please refer to Nada's FAQ page.
