C#打印源碼也是打印控件的功能之一,這里介紹的C#打印源碼可以實現(xiàn)自動打印處理,不過需要mdi文件的支持。

打印的原理是:生成mdi文件,系統(tǒng)碰到mdi的時候會自動以打印的方式處理。所以,不管用什么模板,什么方式;能在PrintPage事件處理中,生成一張要打印內(nèi)容的圖片就OK了!
C#打印源碼如下:
- #region 打印
- private void btnPrint_Click(object sender, EventArgs e)
- {
- //打印預覽
- //PrintPreviewDialog ppd = new PrintPreviewDialog();
- PrintDocument pd = new PrintDocument();
- //設置邊距
- Margins margin = new Margins(20, 20, 20, 20);
- pd.DefaultPageSettings.Margins = margin;
- ////紙張設置默認
- //PaperSize pageSize = new PaperSize("First custom size", 800, 600);
- //pd.DefaultPageSettings.PaperSize = pageSize;
- //打印事件設置
- pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
- //ppd.Document = pd;
- //ppd.ShowDialog();
- try
- {
- pd.Print();
- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message, "打印出錯", MessageBoxButtons.OK, MessageBoxIcon.Error);
- pd.PrintController.OnEndPrint(pd, new PrintEventArgs());
- }
- }
- //打印事件處理
- private void pd_PrintPage(object sender, PrintPageEventArgs e)
- {
- string date = lblDate.Text; //當前日期
- string flowId = lblFlowId.Text; //流水號
- string payDate = PayDate.Year.ToString() + "年" + PayDate.Month.ToString() + "月"; //應收年月
- string adminId = lblAdminId.Text; //操作員編號
- string baseExpense = lblBaseExpense.Text; //應交基本費用
- string fine = lblFine.Text; //罰款數(shù)目
- string upExpense = lblUpExpense.Text; //上月上余
- string actualExpense = txtActualExpense.Text; //實際應交費用
- string chineseExpense = DecimalToChinese.ConvertSum(actualExpense); //實際應交費用的中文大寫
- //讀取圖片模板
- 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);
- }
- ///
- /// 將收費結果填充到圖片模板
- ///
- private void GetResultIntoImage(
- ref Image temp,
- string userId,

- {
- //讀取圖片模板
- Graphics g = Graphics.FromImage(temp);
- Font f = new Font("宋體", 12);
- Brush b = new SolidBrush(Color.Black);
- //填充數(shù)據(jù)到圖片模板(位置要在制作圖片模板的時候度量好)
- g.DrawImage(temp, 0, 0, temp.Width, temp.Height);
- g.DrawString(userId, f, b, 168, 105);

- g.DrawString(flowId, f, b, 535, 105);
- g.DrawString(currentDate, f, b, 535, 134);
