{
string sContent = "Test Print";
Font printTitleFont= new Font("Arial",8,FontStyle.Regular);
StringFormat sLeft=new StringFormat();
sLeft.Alignment=StringAlignment.Near;
e.Graphics.DrawString(sContent,printTitleFont,Brushes.Black,new RectangleF(e.MarginBounds.Left, e.MarginBounds.Top, e.MarginBounds.Width, e.MarginBounds.Height),sLeft);
