PrintDocument,PrintDialog与PrintPreviewDialog

1.使用PrintDocument进行打印

using System;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

namespace PrintTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
//实例化打印对象
PrintDocument printDocument1 = new PrintDocument();
//设置打印用的纸张,当设置为Custom的时候，可以自定义纸张的大小
printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);
//注册PrintPage事件，打印每一页时会触发该事件
printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);
//开始打印
printDocument1.Print();
}
private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
//设置打印内容及其字体，颜色和位置
e.Graphics.DrawString("Hello World！", new Font(new FontFamily("黑体"), 24), System.Drawing.Brushes.Red, 50, 50);
}
}
}

2.使用PrintDialog增加打印对话框

using System;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

namespace PrintTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
//实例化打印对象
PrintDocument printDocument1 = new PrintDocument();
//设置打印用的纸张,当设置为Custom的时候，可以自定义纸张的大小
printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);
//注册PrintPage事件，打印每一页时会触发该事件
printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);

//初始化打印对话框对象
PrintDialog printDialog1 = new PrintDialog();
//将PrintDialog.UseEXDialog属性设置为True，才可显示出打印对话框
printDialog1.UseEXDialog = true;
//将printDocument1对象赋值给打印对话框的Document属性
printDialog1.Document = printDocument1;
//打开打印对话框
DialogResult result = printDialog1.ShowDialog();
if (result == DialogResult.OK)
printDocument1.Print();//开始打印
}
private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
//设置打印内容及其字体，颜色和位置
e.Graphics.DrawString("Hello World！", new Font(new FontFamily("黑体"), 24), System.Drawing.Brushes.Red, 50, 50);
}
}
}

打印对话框如下图所示。

 


3使用PrintPreviewDialog增加打印预览对话框

using System;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;

namespace PrintTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
//实例化打印对象
PrintDocument printDocument1 = new PrintDocument();
//设置打印用的纸张,当设置为Custom的时候，可以自定义纸张的大小
printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);
//注册PrintPage事件，打印每一页时会触发该事件
printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);

//初始化打印预览对话框对象
PrintPreviewDialog printPreviewDialog1 = new PrintPreviewDialog();
//将printDocument1对象赋值给打印预览对话框的Document属性
printPreviewDialog1.Document = printDocument1;
//打开打印预览对话框
DialogResult result = printPreviewDialog1.ShowDialog();
if (result == DialogResult.OK)
printDocument1.Print();//开始打印
}
private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
//设置打印内容及其字体，颜色和位置
e.Graphics.DrawString("Hello World！", new Font(new FontFamily("黑体"), 24), System.Drawing.Brushes.Red, 50, 50);
}
}
}

打印时，会显示下图所示预览画面。

 

 

注意：PrintDialog与PrintPreviewDialog位于名称空间System.Windows.Forms（程序集为System.Windows.Forms.dll）中，而PrintDocument位于名称空间System.Drawing.Printing（程序集为System.Drawing.dll）中。
