Adafruit Nano Thermal Receipt Printer - TTL Serial

Add a really small printer to any microcontroller project with this adorable thermal printer. Thermal printers, commonly used for receipts at ATMs and stores, allow you to embed printing functionalities into your own enclosures.

This thermal printer effortlessly interfaces with microcontrollers, requiring only a 3.3V-5V TTL serial output to print text, barcodes, bitmap graphics, and even QR codes. The package includes a nano thermal receipt printer, a 4-pin TTL cable, and a 16' thermal paper roll.

Designed to use standard 2.25" wide thermal paper, it accommodates up to 16' of paper with a diameter of ≤ 22mm in the bay. This printer is ideal for various projects and comes in multiple sizes based on paper needs, though all share identical operational code. Differences may include baud rates or paper capacity, but functionality remains uniform.

A 5 to 9VDC regulated power supply providing at least 1.5A during high-current printing is necessary, with our 5V 2A power supply serving as an excellent option. We recommend a 2.1mm jack terminal block adapter for convenient power connection.

Standout features include the ability to print bold, underline, and inverted text, set variable line spacing, and adjust text justification (left, center, right). It can handle barcodes in 11 standard formats with adjustable heights, as well as custom bitmap graphics. Our comprehensive tutorial and Arduino library guide you through printing tasks and incorporating QR codes.
