winform简单打印

首先新建一个winform



添加winform中自带的打印控件



winform中有默认的打印控件

　　1.按图片内容将控件拖拽到form中！

　　2.然后将pageSetupDialog1，printDialog1，printPreviewDialog1三个控件中的Document属性指定到printDocument1

　　3.在printDocument1中用到了PrintPage事件，然后其他就是button的按钮事件了

后台代码文件：

//打印
private void button1_Click(object sender, EventArgs e)
{
if (this.printDialog1.ShowDialog() == DialogResult.OK)
{
this.printDocument1.Print();
}
}

//打印设置
private void button2_Click(object sender, EventArgs e)
{
this.pageSetupDialog1.ShowDialog();

}

//打印预览
private void button3_Click(object sender, EventArgs e)
{
this.printPreviewDialog1.ShowDialog();
}

//打印容器设置
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
//打印内容 为 整个Form
//Image myFormImage;
//myFormImage = new Bitmap(this.Width, this.Height);
//Graphics g = Graphics.FromImage(myFormImage);
//g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
//e.Graphics.DrawImage(myFormImage, 0, 0);

//打印内容 为 局部的 this.groupBox1

Bitmap _NewBitmap = new Bitmap(panel1.Width - 2, panel1.Height - 20);
panel1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height);

//打印内容 为 自定义文本内容
//Font font = new Font("宋体", 12);
//Brush bru = Brushes.Blue;
//for (int i = 1; i <= 5; i++)
//{
//    e.Graphics.DrawString("Hello world ", font, bru, i * 20, i * 20);
//}
}
