Design And Implementation Of Printing Subsystem In UEMC

With the development of the network management technology in telecom filed, Datang Telecom has developed the uniform network management system Union Equipment Management Center (UEMC) for its kinds of equipments. But the telecom CP and the customers found that the printing function in the system couldn't meet the special needs in printing large report form pages after the system being put to use. The paper analyzes this problem and presents one solving method to this problem.Firstly, the paper introduces the basic knowledge of report forms' printing technology. The paper analyzes the printing frame structure of the uniform report forms, and carries an indispensable extension based on the specialty of telecom industry. Then, with the theory of landscape orientation pagination printing, the paper introduces the architecture and function specialty of UEMC system, and stresses the character of the printing system, the function demands and the landscape orientation pagination printing technology, and then solves problem of large scale report forms' landscape orientation paged printing by cutting out in pixel. Finally, by the adapted framework and the Java platform's function demands, the paper designs and implements the whole printing subsystem, in which JNI (Java Native Interface) technology is adapted to realize a union interface to the users.
