This system shows the working of “Portable Bluetooth Printer Project”. Here a thermal printer is interfaced with the microcontroller based system and prints the text, numbers and characters on the heat-sensitive paper.
A user can send message from a mobile phone based application which is transferred to the microcontroller based system via Bluetooth signals. Our system makes use of a microcontroller based circuitry interfaced with a printer to achieve this purpose. System makes use of an android application to transmit the text data to be printed through the printer. The data is first transmitted to the circuitry by the app which is received wirelessly through the Bluetooth module. This data is then received by microcontroller and processed to transfer it to the portable Bluetooth mini printer. The controller then processes data received and achieves the printing as per user’s requirement.
