篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了网页WEB打印控件制作 开放源码可以调试相关的知识，希望对你有一定的参考价值。
在WEB系统中，打印的确是比较烦人的问题，如果我们能制作一个属于自己的自定义的打印插件，那么我们在后续自定义打印的时候能随心所欲的控制打印，这样的效果对于程序员来说是非常开心的一件事件，本文将自己开发编写的C# 制作的html打印插件分享出来，让有同样需求的朋友提供一个参考；此插件是基于Microsoft .NET Framework 2.0 开发的，缺点是每台客户端在安装插件时，必须要安装Microsoft .NET Framework 2.0 ；本插件能实现 页眉、页脚、表头、标题、表尾的分页打印；支持纸张类型、自动补充空行等功能；由于技术有限，肯定有很多不足的地方，请批评指正！
由于本打印插件是基于我们开发平台的报表基础来开发设计的，所以打印控件的原理：通过JS将页面表格数据生成固定格式的XML字符串（图片通过64base图片格式）传送给打印插件，有打印插件自主绘图生成打印页面。E_Print插件可以在WEB或WinForm中使用：
打印插件完整源码：E_Print.rar（包含插件源码、打包程序、winform调试DEMO）
也可以在www.sdpsoft.com直接下载
下面贴出源码：（在源码中有详细的注释说明）
