Design And Application Of Cloud Printing System Based On Node.js

Cloud computing,big data and other related improved technologies make online and offline resources fully integrated and form,through analyzing and distributing,into a complete intensive resource set which matches the user data with print data on the Internet,making it real that cloud printing service has gradually taken the place of traditional printing.This paper examines the primary business model of a printing company-a printing system in which the Internet and cloud computing are adopted to enable online orders and payment as well as offline operation for users.The paper also elaborates the design and implementation of cloud printing system based on Node.js.In the paper,the overall structure and functional requirement were first determined on the basis of a detailed and precise requirement analysis achieved by investigating the status quo of cloud printing service at home and abroad and by exploring the difficulties in the company's printing service.In addition,UML use case diagram was adopted to meet the requirements of functional modules including user login,information and data management,transmission and service management of cloud print.Non-functional requirements were also clarified.Then,there was a detailed design of the overall structure,overall function and different functional modules of the system along with the design and perfection of database.Finally,the cloud printing system was completed by virtue of Node.js,B/S network architecture and JAVA programming language.Having undergone tests in terms of the function and performance,the system was qualified to be operated for commercial use.By fully utilizing the big data,the cloud printing system can lower the cost,and give a boost to efficiency,innovation and user satisfaction of the company.
