Aiming at the inefficiency and fallible of manual or semi automatic printing. An expandable educational Self-service technology printing (SSTP) system for educational administration in Chinese university was designed in this paper. This System has developed an efficient, flexible and multi-source certificate generation mode using ADO. Net and Microsoft Office secondary development technology.

Practical application shows that the design of the system has good expansibility and efficiency, it can also meet various needs of self-service printing from other colleges or universities.
