网络打印服务器上水印添加技术的实现

Watermark-adding System on Network Printer Server

讨论了如何在网络打印服务器上实现对打印文档添加水印，解决了实现过程中的一个难点，即如何设定水印的方向及坐标，最后概要地给出了系统的实现框架。该系统在实际的产品应用中取得了令人满意的效果。

This paper discusses the method of adding a watermark for a print page on the network printer server side based on postscript document structure convention, and resolves the problem of how to determine the watermark's orientation and coordinate. An implementation framework of the watermark-adding system is shown at the end of this paper. The application of this system in a product of network printer sever is satisfying.
