Mini thermal printer (RS232)

QR701 Printer:

Print receipts, barcodes, QR codes and even bitmap graphics straight from your microcontroller!

This package comes with a thermal printer including the print head (it does not require ink), a set of power and data cables, and two plastic shims for panel mounting.

Thermal paper 1 roll.

You will also need a 5 to 9VDC regulated power supply, that can provide 1.5A or more during the high-current print

The back panel has 2 3-pin connectors; one for power and one for serial communications. The thermal printer ships with default 19200bps baud rate. If you’re using this printer in conjunction with an Arduino, you’re going to need to connect it to the “Vin” pin and attach an external power supply, as the printer will draw more current than USB is capable of delivering.
