Imports System.Drawing.Printing
Imports ZXing

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ' Load HTML content into the WebBrowser control
        Dim htmlContent As String = "<html><head><style>body { font-family: Arial; } .footer { position: fixed; bottom: 0; text-align: center; }</style></head><body><h1>Your HTML Content Here</h1><div class='footer'><img src='qr-code.png' /></div></body></html>"
        WebBrowser1.DocumentText = htmlContent
    End Sub

    Private Sub PrintDocument()
        ' Print the content in the WebBrowser control

    End Sub

    Private Sub ButtonPrint_Click(sender As Object, e As EventArgs) Handles ButtonPrint.Click

    End Sub

    Private Sub WebBrowser1_DocumentCompleted(sender As Object, e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        ' Once the document is loaded, generate and save QR code image
        GenerateQRCode()
    End Sub

        writer.Format = BarcodeFormat.QR_CODE
        Dim result = writer.Write("Your QR Code Content Here") ' Replace with your QR code content
