這個程序我做了3天，主要是用來將WINFORM的當前活動頁打印出來，2種方法完全不一樣，一種是沒邊框的一種是有邊框的。如圖
有橫向和從向打印，全是用代碼寫稱的（隨便帶了2種最新的IP獲得方法，NET2.0我們都不用原來舊的方法）
源代碼如下：
/// <summary>
/// FormPrint
/// 窗體打印
///
/// 修改紀錄
///
/// 2007.07.31 版本：1.5 JinGangBo 新增獲得本地IP地址與通過域名獲得IP地址
/// 2007.07.30 版本：1.4 JinGangBo 新增設置打印按鈕功能。
/// 2007.07.27 版本：1.3 JinGangBo 實現打印設置，修改橫向打印，新增了焦點和ＥＳＣ，界面排布修改
/// 2007.07.27 版本：1.2 JinGangBo 實現橫向打印和縱向打印，打印預覽最大化，及自動調及100%，及直接打印。
/// 2007.07.26 版本：1.1 JinGangBo 代碼修改與整理
/// 2007.07.26 版本：1.0 JinGangBo 使用2種方法進行了窗體打印
///
/// 版本：1.3

這裏是全部的代碼，我想這個不難吧，有什麼不懂的可以問我，這個程序我已經放在網上了，如果各位想下的話可以點擊這個地址http://download.csdn.net/down/232641/wudiwushen
