打印方法总结

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DataTableDataTable objDataTable = (DataTable)this.dataGridView1.DataSource;2、设置打印时的横坐标和纵坐标int StartX = 0;int StartY = 120;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.Graphics.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.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.DrawString("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.Rows[row];for (int i = 0; i < objDataTable.Columns.Count; i++){e.Graphics.DrawString(objDataRow[i].ToString(), new Font("Arial", 9), 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.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.Printing.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){docToPrint.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{/// <summary>/// PrintService 的摘要说明。
