开放式虚拟打印系统设计与实现

Open Virtual Image Printer System Design and Implementation

在研究虚拟打印系统体系的基础上,建立了适用于应用系统间集成的开放式接口模型。采用 Render Plug-ins方式实现截获打印系统中的打印任务,并对打印结果图像文件进行比例缩放、压缩处理,在 此基础上详细论述虚拟打印系统的对外接口的构成,建立了基于VBA和JNI技术的系统接口模型。

This paper describes the virtual printer system model supported the opened interface to other application system.The virtual printer system provides you with the ability to capture the print job from any application that prints via the Render Plug-ins method. It allows you store image files with upto 24bits per pixel,and also supports all compliant paper sizes and orientations.The interface model makes other application system integrate with the virtual printer.
