Well, my friend. try this in PrintPage event of your PrintDocument object:

<br />
private int LastPrintedLine = 0;<br />
<br />
private void PrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)<br />
        {<br />
            SizeF LineSize = new SizeF();<br />
<br />
            PointF UpperLeftPoint = new PointF(e.MarginBounds.X, e.MarginBounds.Y);<br />
<br />
            RectangleF Rect = new RectangleF();<br />
<br />
            while (true)<br />
            {<br />
                LineSize = e.Graphics.MeasureString(TextHolder.Lines[LastPrintedLine], TextHolder.Font);<br />
<br />
                UpperLeftPoint.Y += Rect.Height;<br />
<br />
                Rect.Location = UpperLeftPoint;<br />
<br />
                Rect.Width = e.MarginBounds.Width;<br />
<br />
                int LineSegments = (int)(LineSize.Width / e.MarginBounds.Width) + 1;<br />
<br />
                Rect.Height = LineSize.Height * LineSegments;<br />
<br />
                e.Graphics.DrawString(TextHolder.Lines[LastPrintedLine], TextHolder.Font,<br />
                                      new SolidBrush(Color.Black), Rect);<br />
<br />
                LastPrintedLine++;<br />
<br />
                if (UpperLeftPoint.Y > e.MarginBounds.Height) break;<br />
<br />
<br />
                if (LastPrintedLine == TextHolder.Lines.Length)<br />
                {<br />
                    e.HasMorePages = false;<br />
                    break;<br />
                }<br />
                else<br />
                    e.HasMorePages = true;<br />
            } <br />
        }<br />
