谁知道System.Drawing.Printing.PrintEventArgs怎么用?给些具体的例子,能不能对打印进行监视?(就是能不能得到一些打印的事件).

对打印进行好好的控制，需要自行继承编辑PrintController子类。

PrintPage事件
这里有个例子

刚做完打印，感觉System.Drawing.Printing.PrintEventArgs很有用，通过该事件类，可以获得打印的区域，打印的graphics对象。对打印进行监视觉得不行，可以用打印监视器类来实现。

打印监视器类?什么东西,哪有?

给你一段代码，你看看

/// 打印水单
/// </summary>
/// <param name="sender"></param>
/// <param name="ev"></param>

str = "欢 迎 光 临";
yPos = topMargin + ((count++) * printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString (str, printFont, Brushes.Black, leftMargin, yPos, new StringFormat());

count++; //加一空行

// printFont = new Font("黑体", 12);
