推荐答案

首先关闭：没有看到代码，很难帮到你。但是，如果要将屏幕控制打印到打印机，请立即停止！



查看设置 PrintDocument [ ^ ]而是以这种方式处理它 - 你会得到更好的结果！该链接有一个简单的例子。

First off: without see the code, it is very difficult to help you much. However, if you are printing screen controls to the printer, stop it now!

Look at setting up a PrintDocument[^] instead, and handling it that way - you will get much better results! The link has a simple example.

您需要使用类 System.Drawing.Printing.PrintDocument 。使用它的想法是：获取System.Drawing.Graphics类的实例并渲染所需的所有图形基元。



请参阅此处的代码示例：

http：/ /msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument(v=VS.100).aspx [ ^ ]，它解释了一切。



此外，请看这篇文章：

在C＃中简化.NET打印 [ ^ ]。

You need to use the class System.Drawing.Printing.PrintDocument. The idea of using it is: you obtain an instance of the class System.Drawing.Graphics and render all the graphical primitive you need.

See the code sample here:
http://msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument(v=VS.100).aspx[^], it explains everything.

它的工作原理，试试这段代码：）

Its working, try this code :)

private void button1_Click(object sender, EventArgs e)
       {
           PrintDocument doc = new PrintDocument();
           doc.PrintPage += this.Doc_PrintPage;
           PrintDialog dlgSettings = new PrintDialog();
           dlgSettings.Document = doc;
           if (dlgSettings.ShowDialog() == DialogResult.OK)
           {
               doc.Print();
           }
       }

private void Doc_PrintPage(object sender, PrintPageEventArgs e)
        {
             float x = e.MarginBounds.Left;
              float y = e.MarginBounds.Top;
            Bitmap bmp = new Bitmap(this.groupBox1.Width, this.groupBox1.Height);
            this.groupBox1.DrawToBitmap(bmp, new Rectangle(0, 0, this.groupBox1.Width, this.groupBox1.Height));
            e.Graphics.DrawImage((Image)bmp, x, y);
        }
