With the introduction and the maturity of cloud computing concepts, technologies such as cloud printing have also emerged. This paper firstly introduces the concept and basic framework of cloud printing, and then builds a cloud printing platform from the client and the server respectively. It meets the requirements for uploading the files to be printed from the client and the management of the print order from the server, and it solves the problems of integration and distribution of printing resources and geographical restrictions of traditional network printing from a technical level. The cloud printing platform system with Android mobile phone as the client realizes online printing anytime and anywhere, which greatly satisfies the needs of users.
