这个程序我做了3天，主要是用来将WINFORM的当前活动页打印出来，2种方法完全不一样，一种是没边框的一种是有边框的。如图
有横向和从向打印，全是用代码写称的（随便带了2种最新的IP获得方法，NET2.0我们都不用原来旧的方法）
源代码如下：
/// <summary>
/// FormPrint
/// 窗体打印
///
/// 修改纪录
///
/// 2007.07.31 版本：1.5 JinGangBo 新增获得本地IP地址与通过域名获得IP地址
/// 2007.07.30 版本：1.4 JinGangBo 新增设置打印按钮功能。
/// 2007.07.27 版本：1.3 JinGangBo 实现打印设置，修改横向打印，新增了焦点和ＥＳＣ，界面排布修改
/// 2007.07.27 版本：1.2 JinGangBo 实现横向打印和纵向打印，打印预览最大化，及自动调及100%，及直接打印。
/// 2007.07.26 版本：1.1 JinGangBo 代码修改与整理
/// 2007.07.26 版本：1.0 JinGangBo 使用2种方法进行了窗体打印
///
/// 版本：1.3
