Adafruit Mini Thermal Receipt Printer

Key Features:

• Mini Thermal Printer
• Ideal for interfacing with a microcontroller
• Print text, barcodes, bitmap graphics, even a QR code
• No ink required

Add a mini 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, you simply need a 3.3V -5V TTL serial output from your microcontroller to print text, barcodes, bitmap graphics, even a QR code!

The printer uses very common 2.25" wide thermal paper, available in any office or stationery supply store. It can fit up to 50 ft of paper in the bay at once. We suggest picking up a 2.1 mm jack terminal block adapter which will make it easy to connect the power adapter. We 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.
