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
打印
2、用Object对象s实现打印
width=10>
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());
}
