This article is to share with you about the specific implementation of the C# printing source code, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it.

C# print source code is also one of the functions of the print control. The C# print source code introduced here can achieve automatic printing processing, but it needs the support of mdi files.

The principle of printing is: the mdi file is generated, and when the system encounters mdi, it will automatically print the file. So, no matter what template or method you use, it's OK to generate a picture of what you want to print in PrintPage event handling!

The C# print source code is as follows:

# region print private void btnPrint_Click (object sender, EventArgs e) {/ / print Preview / / PrintPreviewDialog ppd = new PrintPreviewDialog (); PrintDocument pd = new PrintDocument (); / / set margins Margins margin = new Margins (20, 20, 20); pd.DefaultPageSettings.Margins = margin / Paper setting default / / PaperSize pageSize = new PaperSize ("First custom size", 800,600); / / pd.DefaultPageSettings.PaperSize = pageSize; / / print event setting pd.PrintPage + = new PrintPageEventHandler (this.pd_PrintPage); / / ppd.Document = pd; / / ppd.ShowDialog () Try {pd.Print ();} catch (Exception ex) {MessageBox.Show (ex.Message, "print error", MessageBoxButtons.OK, MessageBoxIcon.Error); pd.PrintController.OnEndPrint (pd, new PrintEventArgs ()) }} / / print event handling private void pd_PrintPage (object sender, PrintPageEventArgs e) {string date = lblDate.Text; / / current date string flowId = lblFlowId.Text; / / serial number string payDate = PayDate.Year.ToString () + "year" + PayDate.Month.ToString () + "month" / / year / month receivable string adminId = lblAdminId.Text; / / operator No. String baseExpense = lblBaseExpense.Text; / / basic fee payable string fine = lblFine.Text; / / number of fines string upExpense = lblUpExpense.Text; / / the last month remaining string actualExpense = txtActualExpense.Text / / actual fee payable string chineseExpense = DecimalToChinese.ConvertSum (actualExpense); / / Chinese capitalization of actual fee payable / / read picture template 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) } / populate the charging result into the image template / 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) {/ / read picture template Graphics g = Graphics.FromImage (temp) Font f = new Font ("Arial", 12); Brush b = new SolidBrush (Color.Black); / / fill data into the picture template (location should be measured when making the picture template) 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, 176269); g.DrawString (adminName, f, b, 497,298); g.Dispose () } # endregion above is the specific implementation of the C# print source code.
