C Bar Code Generation and Printing Instance Code

In this paper, we share the method of C # barcode generation and printing for your reference. The specific contents are as follows

string BarcodeString = "13043404455";// Bar code 
  int ImgWidth = 520;
  int ImgHeight = 120;

  // Print button 
  private void button1_Click(object sender, EventArgs e)
  {
   // Instantiate a print object 
   PrintDocument printDocument1 = new PrintDocument();

   // Set the paper for printing , You can customize the size of the paper ( Unit: mm).   It may not be set when the print height is uncertain 
   //printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 585, 800);

   // Registration PrintPage Event, print every 1 This event is triggered when the 
   printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);

   // Start printing 
   printDocument1.Print();

   // Print preview 
   //PrintPreviewDialog ppd = new PrintPreviewDialog();
   //ppd.Document = printDocument1;
   //ppd.ShowDialog();
  }
