## Description

Add a *really small* printer to any microcontroller project with this very cute thermal printer. 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 or computer, as you just plug it in via **USB** ***or* TTL Serial** to print text, barcodes, bitmap graphics, even a QR code!

**This package comes with a Mini Thermal Receipt Printer, a USB cable, a JST cable, and a 4-pin TTL cable. One 33' roll of thermal paper is also included!** The printer uses very common 2.25" wide thermal paper, and it can fit up to 33 ft of paper in the bay at once with a diameter of = 30mm. [The 33' long, 2.25" wide Thermal Paper Roll in Adafruit's store works perfectly](https://core-electronics.com.au/thermal-paper-roll-33-long-2-25.html)!

Adafruit have quite a few sizes of embeddable thermal printers, larger ones can hold more paper in the bay, but are of course larger. All are identical 'code wise', although some have slightly different baud rates. [Check out Adafruit's full range of thermal printers!](https://www.adafruit.com/search?q=thermal+printer&b=1)

You will also need a 5 to 9V regulated power supply, that can provide 1.5A or more during the high-current print - [Adafruit's 5V 2A switching power supply](https://core-electronics.com.au/5v-2a-2000ma-switching-power-supply-ul-listed.html) will work very nicely. You'll need to give that external power if you are using USB for power, you cannot power it over the USB cable.

Adafruit really like this printer because its 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.**

Of course, Adafruit wouldn't leave you with a datasheet and a "good luck!" - Adafruit have a full tutorial and matching Arduino library that demonstrates the following:

- Printing with small, medium and large text
- **Bold**  and underline text
- Inverted text
- Variable line spacing
- Left, center and right justification
- Barcodes in the following standard formats: **UPC A, UPC E, EAN13, EAN8, CODE39, I25, CODEBAR, CODE93, CODE128, CODE11** and **MSI** - with adjustable barcode height
- Custom monochrome bitmap graphics!
- How to include a QR code

[If you're using the built-in USB chip instead of TTL serial, you can use Adafruit's Python example code](https://github.com/adafruit/Python-Thermal-Printer)
