Nano Thermal Receipt Printer - TTL Serial

Nano Thermal Receipt Printer - TTL Serial info

Thermal printers are also known as receipt printers, they're what you get when you go to the ATM or grocery store. Now you can embed a little printer of your own into an enclosure. This printer is ideal for interfacing with a microcontroller, you simply need a 3.3V-5V TTL serial output from your microcontroller to print text, barcodes, bitmap graphics, even a QR code.

This package comes with a Nano Thermal Receipt Printer and a 4-pin TTL cable. One 16' roll of thermal paper is also included. The printer uses very common 2.25" wide thermal paper, and it can fit up to 16' of paper in the bay at once with a diameter of ≤ 22mm.

To power the thermal printer, you will also need a 5V to 9V DC regulated power supply that can provide 1.5A or more during the high-current print.

This thermal printer is great because it is easy to make bold, underline, inverted text, variable line spacing, left/center/right justification, barcodes in 11 standard formats with adjustable height, and even custom bitmap graphics. Also there is an Arduino library and tutorial provided by Adafruit, so it won’t be hard for you to start using this thermal printer.
