With the popularization and use of self-service mobile terminals, many government departments have adopted intelligent self-service mobile terminals to improve the service efficiency of the government and facilitate the needs of the people, which is a real embodiment of serving the people.     The government's intelligent self-service mobile terminal greatly solves the current situation of limited government human resources and many people's needs, improves service efficiency, and avoids the situation that the people need to go to the government many times for one thing.     The government intelligent self-service mobile terminal is mostly used for business license certificate service, tax self-payment service, electricity and water fee self-service payment service, human file self-service inquiry service, etc.     Most of these services require printing. At this time, Xiamen APT's embedded printers can help solve the problem. Our embedded printers are small in size and do not take up too much space, easy to install, plug and play, and extremely convenient.
