1、一、放三个有关打印的控件printDialog、printDocument、printPreviewDialog二、设置printPreviewDialog控件的Document属性，该属性一般会设置为printDocument控件三、写printDocument中的PrintPage事件，在该事件设置打印的位置和样式 例如： 1、从控件中取出数据放入DataTable DataTable objDataTable = (DataTable)this.dataGridView1.DataSource; 2、设置打印时的横坐标和纵坐标 int StartX = 0; int StartY = 1
2、20; 3、设置标题的内容、字体、字体大小、颜色、坐标位置 e.Graphics.DrawString(广东步步高电子工业有限公司出库批次情况, new Font(Arial, 20), Brushes.Black, 100, 40); e.Graphics.DrawString(打印时间： + DateTime.Now.ToString(), new Font(Arial, 8), Brushes.Red, 560, 100); e.Graphics.DrawString(单号, new Font(Arial, 10), Brushes.Red, StartX, StartY); e.Gra
3、phics.DrawString(批号, new Font(Arial, 10), Brushes.Red, StartX + 95, StartY); e.Graphics.DrawString(区域编号, new Font(Arial, 10), Brushes.Red, StartX + 190, StartY); e.Graphics.DrawString(品种, new Font(Arial, 10), Brushes.Red, StartX + 285, StartY); e.Graphics.DrawString(规格, new Font(Arial, 10), Brushes.
4、Red, StartX + 380, StartY); e.Graphics.DrawString(计划发货数, new Font(Arial, 10), Brushes.Red, StartX + 475, StartY); e.Graphics.DrawString(实际发货数, new Font(Arial, 10), Brushes.Red, StartX + 570, StartY); e.Graphics.DrawString(发货日期, new Font(Arial, 10), Brushes.Red, StartX + 665, StartY); e.Graphics.Draw
5、String(员工编号, new Font(Arial, 10), Brushes.Red, StartX + 760, StartY); 4、从DataTable中读出数据 for (int row = 0; row objDataTable.Rows.Count; row+) DataRow objDataRow = objDataTable.Rowsrow; for (int i = 0; i objDataTable.Columns.Count; i+) e.Graphics.DrawString(objDataRowi.ToString(), new Font(Arial, 9),
6、Brushes.Black, StartX, StartY + 50); e.Graphics.DrawString(-, new Font(Arial, 10), Brushes.Blue, StartX, StartY + 70); StartX = StartX + 95; StartX = 0; StartY += 50; 四、然后打印 （也就是点击打印按钮或者别的控件） 1、设置显示页面的大小 printPreviewDialog1.PrintPreviewControl.Zoom = 1.0; 2、设置宽度和高度 printPreviewDialog1.Width = Screen
7、.PrimaryScreen.Bounds.Width; printPreviewDialog1.Height = Screen.PrimaryScreen.Bounds.Height; printPreviewDialog1.ShowDialog();在C#中使用PrintDialog可以很方便的实现程序的打印功能。 其步骤如下： 创建一个PrintDialog的实例。如下： System.Windows.Forms.PrintDialog PrintDialog1=new PrintDialog (); 创建一个PrintDocument的实例.如下： System.Drawing.Pri
8、nting.PrintDocument docToPrint = new System.Drawing.Printing.PrintDocument(); 设置打印机开始打印的事件处理函数.函数原形如下： void docToPrint_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) 将事件处理函数添加到PrintDocument的PrintPage事件中。 docToPrint.PrintPage+=new PrintPageEventHandler(docToPrint_PrintPage); 设
9、置PrintDocument的相关属性，如： PrintDialog1.AllowSomePages = true;PrintDialog1.ShowHelp = true; 把PrintDialog的Document属性设为上面配置好的PrintDocument的实例： PrintDialog1.Document = docToPrint; 调用PrintDialog的ShowDialog函数显示打印对话框： DialogResult result = PrintDialog1.ShowDialog(); 根据用户的选择，开始打印： if (result=DialogResult.OK) d
10、ocToPrint.Print(); 例子如下： 使用时先创建PrintService类的实例，然后调用void StartPrint(Stream streamToPrint,string streamType)函数开始打印。其中streamToPrint是要打印的内容（字节流），streamType是流的类型（txt表示普通文本，image表示图像）； - using System; using System.Drawing.Printing; using System.Windows.Forms; using System.IO; namespace EDImageSystem / /
11、PrintService 的摘要说明。 / public class PrintService public PrintService() / / TODO: 在此处添加构造函数逻辑 / this.docToPrint.PrintPage+=new PrintPageEventHandler(docToPrint_PrintPage); /将事件处理函数添加到PrintDocument的PrintPage中 / Declare the PrintDocument object. private System.Drawing.Printing.PrintDocument docToPrint =
12、 new System.Drawing.Printing.PrintDocument();/创建一个PrintDocument的实例 private System.IO.Stream streamToPrint; string streamType; / This method will set properties on the PrintDialog object and / then display the dialog. public void StartPrint(Stream streamToPrint,string streamType) this.streamToPrint=s
13、treamToPrint; this.streamType=streamType; / Allow the user to choose the page range he or she would / like to print. System.Windows.Forms.PrintDialog PrintDialog1=new PrintDialog ();/创建一个PrintDialog的实例。 PrintDialog1.AllowSomePages = true; / Show the help button. PrintDialog1.ShowHelp = true; / Set the Document property to the PrintDocument for / which the PrintPage Event has been handled. To di
