How to fit all columns of data grid view in print preview in vb - mysql

Question

I have been trying to expand the print preview paper size to landscape to show the printed data grid view. I have more than 7 columns and the last 2 columns did not fit in the whole paper. The code for printing data grid view values is working well. But not the way I want it to appear on the print preview. This is how it looks like: screenshot: https://snipboard.io/AeVfPN.jpg
This is how I want it to look to fit the entire paper: https://i.stack.imgur.com/yPOEm.png
This is my code:
Dim mRow As Integer = 0
Dim newpage As Boolean = True
Private Sub PrintDocument1_PrintPage(sender As System.Object, e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim mRow As Integer = 0
Dim newpage As Boolean = True
With DataGridView1
Dim fmt As StringFormat = New StringFormat(StringFormatFlags.LineLimit)
fmt.LineAlignment = StringAlignment.Center
fmt.Trimming = StringTrimming.EllipsisCharacter
Dim y As Single = e.MarginBounds.Top
Do While mRow < .RowCount
Dim row As DataGridViewRow = .Rows(mRow)
Dim x As Single = e.MarginBounds.Left
Dim h As Single = 0
For Each cell As DataGridViewCell In row.Cells
Dim rc As RectangleF = New RectangleF(x, y, cell.Size.Width, cell.Size.Height)
e.Graphics.DrawRectangle(Pens.Black, rc.Left, rc.Top, rc.Width, rc.Height)
If (newpage) Then
e.Graphics.DrawString(DataGridView1.Columns(cell.ColumnIndex).HeaderText, .Font, Brushes.Black, rc, fmt)
Else
e.Graphics.DrawString(DataGridView1.Rows(cell.RowIndex).Cells(cell.ColumnIndex).FormattedValue.ToString(), .Font, Brushes.Black, rc, fmt)
End If
x += rc.Width
h = Math.Max(h, rc.Height)
Next
newpage = False
y += h
mRow += 1
If y + h > e.MarginBounds.Bottom Then
e.HasMorePages = True
mRow -= 1
newpage = True
Exit Sub
End If
Loop
mRow = 0
End With
End Sub
Private Sub btnPrint_Click(sender As Object, e As EventArgs) Handles btnPrint.Click
PrintPreviewDialog1.Document = PrintDocument1
PrintPreviewDialog1.ShowDialog()
End Sub
Private Sub PrintDocument1_BeginPrint(sender As Object,
e As PrintEventArgs) Handles PrintDocument1.BeginPrint
mRow = 0
newpage = True
PrintPreviewDialog1.PrintPreviewControl.StartPage = 0
PrintPreviewDialog1.PrintPreviewControl.Zoom = 1.0
End Sub
