1.應用PrintDocument停止打印

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)
    {
      //實例化打印對象
      PrintDocument printDocument1 = new PrintDocument();
      //設置打印用的紙張,當設置為Custom的時刻，可以自界說紙張的年夜小
      printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);
      //注冊PrintPage事宜，打印每頁時會觸發該事宜
      printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);
      //開端打印
      printDocument1.Print();
    }
    private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
      //設置打印內容及其字體，色彩和地位
      e.Graphics.DrawString("Hello World！", new Font(new FontFamily("黑體"), 24), System.Drawing.Brushes.Red, 50, 50);
    }
  }
}

2.應用PrintDialog增長打印對話框

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)
    {
      //實例化打印對象
      PrintDocument printDocument1 = new PrintDocument();
      //設置打印用的紙張,當設置為Custom的時刻，可以自界說紙張的年夜小
      printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);
      //注冊PrintPage事宜，打印每頁時會觸發該事宜
      printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);
   
      //初始化打印對話框對象
      PrintDialog printDialog1 = new PrintDialog();
      //將PrintDialog.UseEXDialog屬性設置為True，才可顯示出打印對話框
      printDialog1.UseEXDialog = true;
      //將printDocument1對象賦值給打印對話框的Document屬性
      printDialog1.Document = printDocument1;
      //翻開打印對話框
      DialogResult result = printDialog1.ShowDialog();
      if (result == DialogResult.OK)         
        printDocument1.Print();//開端打印
    }
    private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
      //設置打印內容及其字體，色彩和地位
      e.Graphics.DrawString("Hello World！", new Font(new FontFamily("黑體"), 24), System.Drawing.Brushes.Red, 50, 50);
    }
  }
}

打印對話框以下圖所示。

3.應用PrintPreviewDialog增長打印預覽對話框

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)
    {
      //實例化打印對象
      PrintDocument printDocument1 = new PrintDocument();
      //設置打印用的紙張,當設置為Custom的時刻，可以自界說紙張的年夜小
      printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 500, 500);
      //注冊PrintPage事宜，打印每頁時會觸發該事宜
      printDocument1.PrintPage += new PrintPageEventHandler(this.PrintDocument_PrintPage);
   
      //初始化打印預覽對話框對象
      PrintPreviewDialog printPreviewDialog1 = new PrintPreviewDialog();
      //將printDocument1對象賦值給打印預覽對話框的Document屬性
      printPreviewDialog1.Document = printDocument1;
      //翻開打印預覽對話框
      DialogResult result = printPreviewDialog1.ShowDialog();
      if (result == DialogResult.OK)         
        printDocument1.Print();//開端打印
    }
    private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
      //設置打印內容及其字體，色彩和地位
      e.Graphics.DrawString("Hello World！", new Font(new FontFamily("黑體"), 24), System.Drawing.Brushes.Red, 50, 50);
    }
  }
}

打印時，會顯示下圖所示預覽畫面。

留意：PrintDialog與PrintPreviewDialog位於稱號空間System.Windows.Forms（法式集為System.Windows.Forms.dll）中，而PrintDocument位於稱號空間System.Drawing.Printing（法式集為System.Drawing.dll）中。
