Hello Friends,
If you are doing any Project in which receipt is required or token need to be print, you can add a mini thermal printer to your microcontroller project. With this very cute thermal printer your project features get value added advantages.
In this video we have explained the interfacing technique with sample example codes.
Thermal printers are also known as receipt printers, they're what you get when you go to the ATM , Buses, bank or grocery store. Now you can embed a little printer of your own into an enclosure with your project. This printer is ideal for interfacing with a microcontroller, you simply need serial output from your microcontroller to print text, barcodes, bitmap graphics, even a QR code!
This type of package comes with a thermal printer including the print head (it does not require ink, a set of power and data cables). The thermal paper used in printer, you can buy from near by stationary store for around 25-30/- each.
It requires power supply of 5 -12 volts. You need to connect RXD and TXD pin to the TXD and RXD pin of microcontroller respectively. There are some specific commands by which you can make BOLD font also, that commands may be line feed, new line, etc. You can print any alphanumeric character with this printer , even you can print Bar code and QR code, but for that you have to set it though Serial Port.
We have shown some commands in this video, hope so you will get something new.
Applications of are
1) Bus Tickets
2) Banks Token
3) Cinema Halls
4) Shopping Malls
5) Restaurants etc.
So friends try to interface it with your project.
