Wireless Thermal Printer Based on Internet of Things

Abstract

This paper presents a GPRS thermal printer which is based on Internet of Things. The main control chip of the printer initializes the GPRS module, connects the restaurant reservation website servers and cell phones, and accepts orders from Internet and phone messages. Then the printer prints two same receipts. Meanwhile the information on the reservation is saved in SD card. After confirmation of orders, confirmation information would be sent back to relevant network ports or phones so that they can reaffirm each other. A GPRS wireless thermal printer which is based on Internet of Things can print the customers’ order timely and remind staff to handle them in time. It can be widely used in restaurant reservation website and other relevant service.
