Description

Add a small printer to all your projects at base of microcontroller with this mini thermal printer. These printers have often used to print a receipt when shopping. Now, you can use it with your micro-controllers simply with a simple serial TTL 3, 3v - 5V to print text, images, bar codes, or even a QR code.

This product consists of a mini thermal printer including the print head which does not require ink cartridges. Thermal paper is not provided. The printer requires rolls of thermal paper with a width of 2.25 "and an easy commute playtime ' to 50 ft. You must also supply a 5V or 9V DC which can provide 1.5 and more during the peak current during printing, a 5V 2A power supply is perfect for this product. We also suggest you to buy with one or two thermal paper rolls.

We really like this printer because it is easy to print in bold, underlined or reverse-text, spacing line spacing is variable, with some justification to left/center/right and 11 standard bar code bar. It is possible to print images in bitmap format.
