29. {
30. this.printDocument1.Print();

36. {
37. ////打印内容 为 整个Form
38. //Image myFormImage;
39. //myFormImage &＃61; new Bitmap(this.Width, this.Height);
40. //Graphics g &＃61; Graphics.FromImage(myFormImage);
41. //g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
42. //e.Graphics.DrawImage(myFormImage, 0, 0);
44. ////打印内容 为 局部的 this.groupBox1
45. //Bitmap _NewBitmap &＃61; new Bitmap(groupBox1.Width, groupBox1.Height);
