C# Winform 无弹窗打印实例

在Winform 中可以通过打印控件方便的实现应用程序打印功能，本文将使用一个简单实例进行演示。

操作步骤：

1、新建winform项目及创建窗体

2、拖取 打印 相关控件

PrintDialog 、 PrintDocument

3、设置打印按钮等控件 及 添加相应按钮事件

4、示意代码如下：

public partial class Form3 : Form

{

public Form3()

{

InitializeComponent();

this.printDocument1.OriginAtMargins = true;//启用页边距

this.pageSetupDialog1.EnableMetric = true; //以毫米为单位

}

//打印设置

private void btnSetPrint_Click(object sender, EventArgs e)

{

this.pageSetupDialog1.ShowDialog();

}

//打印预览

private void btnPrePrint_Click(object sender, EventArgs e)

{

this.printPreviewDialog1.ShowDialog();

}

//打印

private void btnPrint_Click(object sender, EventArgs e)

{

this.printDialog1.PrinterSettings.PrinterName = "Microsoft XPS Document Writer";

this.printDocument1.Print();

}

//打印内容的设置

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(groupBox1.Width, groupBox1.Height);

//groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));

//e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height);

}

}

}
