实现打印功能的代码

一、js实现打印功能代码

1、js自带功能实现打印

    <a   href= "javascript:window.print(); "> 打印 </a> 2、用Object对象s实现打印 <OBJECT   classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2   height=10   id="WebBrowser" width=10> </OBJECT>   

   <script   language= "JavaScript "> 

       //获取页面object对象

       var WB =  $("#WebBrowser")       function   doPrintSetup(){            //打印设置             WB.ExecWB(8,1)       }       function   doPrintPreview(){           //打印预览           WB.ExecWB(7,1)       }       function   doprint(){           //直接打印          WB.ExecWB(6,6)      }    </script>

二、C#打印代码

 

第一步 基本操作

定义 一个C#提供的 PrintDocument 对象

private PrintDocument printDocument;

 

第二步

//写一个方法 对打印事件进行初始化

private void PrintDocument()        {            printDocument = new PrintDocument();            printDocument.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);        }

 

//

 

第三步

事件响应方法

private void printDocument_PrintPage(object sender, PrintPageEventArgs e)        {            //StringReader lineReader = new StringReader(textBox.Text);            Graphics graphic = e.Graphics;//获取绘图对象            float linesPerPage = 0;//页面行号            float yPosition = 0;//绘制字符串的纵向位置            float leftMargin = e.MarginBounds.Left;//左边距            float topMargin = e.MarginBounds.Top;//上边距            string line = string.Empty;//读取的行字符串            int currentPageLine = 0;//当前页读取的行数            Font charFont = button1.Font;//获取打印字体            SolidBrush brush = new SolidBrush(Color.Black);//刷子            linesPerPage = e.MarginBounds.Height / charFont.GetHeight(graphic);//每页可打印的行数            //countNum记录全局行数，currentPageLine记录当前打印页行数。            // graphic.DrawString("水费通知单", charFont, brush, 360, 100, new StringFormat());

            //房产地址textbox3            //租户名字textbox2            // 上次缴费记录 textbox5            //费用到期 textbox7            //合同开始时间 textbox4            //合同到期时间 textbox6            //月租金 textbox8            //月管理费 textbox9            //缴费租金 textbox11            //缴费管理费 textbox10            //总计   textbox12

            graphic.DrawString("武大教育发展有限公司房屋租金缴费登记", charFont, brush, 300, 100, new StringFormat());            graphic.DrawString("租户:         " + this.textBox2.Text, charFont, brush, 100, 140, new StringFormat());            graphic.DrawString("合同号:       " + this.textBox1.Text, charFont, brush, 100, 180, new StringFormat());            graphic.DrawString("房产地址:     " + this.textBox3.Text, charFont, brush, 100, 220, new StringFormat());            graphic.DrawString("月租金:       " + this.textBox8.Text, charFont, brush, 100, 260, new StringFormat());            graphic.DrawString("月管理费:     " + this.textBox9.Text, charFont, brush, 100, 300, new StringFormat());            graphic.DrawString("上次缴费至:   " + this.textBox7.Text, charFont, brush, 100, 340, new StringFormat());            graphic.DrawString("本次缴费至:   " + this.dateTimePicker1.Text, charFont, brush, 100, 370, new StringFormat());            graphic.DrawString("租金:         " + this.textBox11.Text, charFont, brush, 100, 410, new StringFormat());            graphic.DrawString("管理费:       " + this.textBox10.Text, charFont, brush, 100, 450, new StringFormat());            graphic.DrawString("合计:         " + this.textBox12.Text, charFont, brush, 100, 490, new StringFormat());            graphic.DrawString("备注:", charFont, brush, 100, 530, new StringFormat());            DateTime today = DateTime.Now;            string day = today.Date.ToString();

            graphic.DrawString("武大教育发展有限责任公司 " + day, charFont, brush, 580, 1100, new StringFormat());

        }

 

 

第四步 调用 打印 和预览打印

 

this.PrintDocument();                PrintDialog print = new PrintDialog();                //将初始化后的printDocument赋给print.Document                print.Document = printDocument;

try                {                    if (print.ShowDialog() == DialogResult.OK)                    {                        //打印时直接调用PrintDocument的Print方法                        printDocument.Print();                    }                }                catch (Exception ex)                {                    MessageBox.Show("打印出错:" + ex.ToString());                    //出错则结束打印过程                    printDocument.PrintController.OnEndPrint(printDocument, new PrintEventArgs());                }

 

打印预览

   PrintPreviewDialog printPreview = new PrintPreviewDialog();            //初始化PrintDocument            this.PrintDocument();            //将初始化后的printDocument赋给print.Document            printPreview.Document = printDocument;            try            {                printPreview.ShowDialog();            }            catch (Exception ex)            {                MessageBox.Show(ex.ToString());            }
