C#打印图片，转载一下

打印的原理是：生成mdi文件，系统碰到mdi的时候会自动以打印的方式处理。所以，不管用什么模板，什么方式；能在PrintPage事件处理中,生成一张要打印内容的图片就OK了!

 

C#实现打印源码如下：

 

#region 打印

        private void btnPrint_Click(object sender, EventArgs e)

        {

            //打印预览

            //PrintPreviewDialog ppd = new PrintPreviewDialog();

            PrintDocument pd = new PrintDocument();

            //设置边距

            Margins margin = new Margins(20, 20, 20, 20);

            pd.DefaultPageSettings.Margins = margin;

            ////纸张设置默认

            //PaperSize pageSize = new PaperSize("First custom size", 800, 600);

            //pd.DefaultPageSettings.PaperSize = pageSize;

            //打印事件设置

            pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);

            //ppd.Document = pd;

            //ppd.ShowDialog();

            try

            {

                pd.Print();

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message, "打印出错", MessageBoxButtons.OK, MessageBoxIcon.Error);

                pd.PrintController.OnEndPrint(pd, new PrintEventArgs());

            }

        }

        //打印事件处理

        private void pd_PrintPage(object sender, PrintPageEventArgs e)

        {

            string date = lblDate.Text; //当前日期

            string flowId = lblFlowId.Text; //流水号

            string payDate = PayDate.Year.ToString() + "年" + PayDate.Month.ToString() + "月"; //应收年月

            string adminId = lblAdminId.Text; //操作员编号

            string baseExpense = lblBaseExpense.Text; //应交基本费用

            string fine = lblFine.Text; //罚款数目

            string upExpense = lblUpExpense.Text; //上月上余

            string actualExpense = txtActualExpense.Text; //实际应交费用

            string chineseExpense = DecimalToChinese.ConvertSum(actualExpense); //实际应交费用的中文大写



            //读取图片模板

            Image temp = Image.FromFile(@"Receipts.jpg");

            GetResultIntoImage(ref temp, UserId, flowId, date, baseExpense, fine, upExpense, actualExpense, chineseExpense, payDate, adminId);

            int x = e.MarginBounds.X;

            int y = e.MarginBounds.Y;

            int width = temp.Width;

            int height = temp.Height;

            Rectangle destRect = new Rectangle(x, y, width, height);

            e.Graphics.DrawImage(temp, destRect, 0, 0, temp.Width, temp.Height, System.Drawing.GraphicsUnit.Pixel);

        }



        /// <summary>

        /// 将收费结果填充到图片模板

        /// </summary>

        private void GetResultIntoImage(

            ref Image temp,

            string userId,

            string flowId,

            string currentDate,

            string baseExpense,

            string fine,

            string upExpense,

            string actualExpense,

            string chineseExpense,

            string payDate,

            string adminName)

        {

            //读取图片模板

            Graphics g = Graphics.FromImage(temp);



            Font f = new Font("宋体", 12);

            Brush b = new SolidBrush(Color.Black);

            

   //填充数据到图片模板（位置要在制作图片模板的时候度量好）

            g.DrawImage(temp, 0, 0, temp.Width, temp.Height);

            g.DrawString(userId, f, b, 168, 105);

            g.DrawString(UserName, f, b, 166, 134);

            g.DrawString(flowId, f, b, 535, 105);

            g.DrawString(currentDate, f, b, 535, 134);

            g.DrawString(baseExpense, f, b, 219, 202);

            g.DrawString(fine, f, b, 372, 202);

            g.DrawString(upExpense, f, b, 486, 202);

            g.DrawString(actualExpense, f, b, 596, 202);

            g.DrawString(chineseExpense, f, b, 196, 238);

            g.DrawString(payDate, f, b, 176, 269);

            g.DrawString(adminName, f, b, 497, 298);



            g.Dispose();

        }
