Printer and POS machine program
Printers have increased rapidly in recent years, with the continuous growth of China's economy, the continuous advancement of electronic information management such as the Three Gold Project, and the continuous improvement of service levels in industries such as commercial/retail, finance, communications, transportation/transport. At present, the application of thermal label printers in China has entered a period of rapid popularization, and the market size continues to grow rapidly.
