How to print the barcode in Windows Forms?

Syncfusion WinForms Barcode control  helps rendering barcodes in desktop application. The control can be merged with any desktop application and easy to encode text using the supported symbol types. The basic structure of a barcode consists of a leading and trailing quiet zone, a start pattern, one or more data characters, optionally one or two check characters, and a stop pattern. Using this control, you can print the barcode in Windows Forms.

Steps to print the barcode programmatically:

1. Create a new C# Windows Forms application project.

2. Install the Syncfusion.SfBarcode.Windows NuGet package as reference to your .NET Framework application from NuGet.org.

3. Include the following namespaces in the Form1.Designer.cs file.

   // [C# Code]
   using System.Drawing;
   using System.Drawing.Printing;
   using Syncfusion.Windows.Forms.Barcode;
   using System.Windows.Forms;
   

' [VB Code]
Imports System.Drawing
Imports System.Drawing.Printing
Imports Syncfusion.Windows.Forms.Barcode
Imports System.Windows.Forms

4. Use the following code snippet to print the barcode.

   // [C# Code]
   //Initialize the Barcode control
   SfBarcode barcode = new SfBarcode();
   //Set the barcode symbology type
   barcode.Symbology = BarcodeSymbolType.Code128A;
   //Set the input text
   barcode.Text = textBox1.Text;
   //Set the barcode size
   barcode.Size = pictureBox1.Size;
   //Export the Barcode control as image
   pictureBox1.Image = barcode.ToImage();
   bitmap = new Bitmap(barcode.ToImage());
   //Initialize the print document
   PrintDocument printDocument = new PrintDocument();
   PrintDialog pdialog = new PrintDialog();
   if (pdialog.ShowDialog() == DialogResult.OK)
   {
       printDocument.PrinterSettings.PrinterName = pdialog.PrinterSettings.PrinterName;
       //Triggers to print current page
       printDocument.PrintPage += printDocument_PrintPage;
       printDocument.Print();
   }
    
   // Event handler to save the PrintDocument page as image
   void printDocument_PrintPage(object sender, PrintPageEventArgs e)
   {
       //Draw barcode into PDF page
       e.Graphics.DrawImage(bitmap, 0, 0);
       e.HasMorePages = false;
   }
   

' [VB Code]
'Initialize the Barcode control
Dim barcode As New SfBarcode()
'Set the barcode symbology type
barcode.Symbology = BarcodeSymbolType.Code128A
'Set the input text
barcode.Text = TextBox1.Text
'Set the barcode size
barcode.Size = PictureBox1.Size
'Export the Barcode control as image
PictureBox1.Image = barcode.ToImage()
Bitmap = New Bitmap(barcode.ToImage())
'Initialize the print document
Dim printDocument As New PrintDocument()
Dim pdialog As New PrintDialog()
If pdialog.ShowDialog() = DialogResult.OK Then
    printDocument.PrinterSettings.PrinterName = pdialog.PrinterSettings.PrinterName
    'Triggers to print current page
    AddHandler printDocument.PrintPage, AddressOf printDocument_PrintPage
    printDocument.Print()
End If
 
'Event handler to save the PrintDocument page as image
Private Sub printDocument_PrintPage(sender As Object, e As PrintPageEventArgs)
    'Draw barcode into PDF page
    e.Graphics.DrawImage(Bitmap, 0, 0)
    e.HasMorePages = False
End Sub
