You can also use the print preview option to complete this process.

// This is for the print preview event
 private void printPreviewDialog1_Load(object sender, EventArgs e)
 {
     int j = 0;
     z = 185;

     while (j < dataGridView1.Rows.Count)
     {                 
         j += 1;
         z += 30;
     }

     z += 60;

     PaperSize pkCustomSize1 = new PaperSize("First custom size", 350, z);

     printDocument1.DefaultPageSettings.PaperSize = pkCustomSize1;
 }

 // This is the loop for generating print Document
 private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
 {
     int i = 0; //For Gridview Row Count
     int sno = 1; //For Grid Serial Number

     e.Graphics.DrawString(
         "HEADING", 
         new Font("Calibri", 20, FontStyle.Bold), 
         Brushes.Black, 
         new Point(100, 5));

     e.Graphics.DrawString(
         "Address", 
         new Font("Calibri", 12, FontStyle.Bold), 
         Brushes.Black, 
         new Point(75, 35));

    int y = 185; //For Grid y axis start to print 

    while (i < dataGridView1.Rows.Count)
    {
        e.Graphics.DrawString(
            sno.ToString(), 
            new Font("Calibri", 10, FontStyle.Bold), 
            Brushes.Black, 
            new Point(10, y)); //For Serial Number

        e.Graphics.DrawString(
            dataGridView1.Rows[i].Cells[1].FormattedValue.ToString(), 
            new Font("Calibri", 10, FontStyle.Bold), 
            Brushes.Black, 
            new Point(240, y));

        //This is for Trim content to next line
        Graphics df1 = e.Graphics;
        SizeF ef1 = df1.MeasureString(
            dataGridView1.Rows[i].Cells[0].FormattedValue.ToString(),
            new Font(new FontFamily("Calibri"), 12F, FontStyle.Bold),
            200); //160

        df1.DrawString(
            dataGridView1.Rows[i].Cells[0].FormattedValue.ToString(),
            new Font(new FontFamily("Calibri"), 12F, FontStyle.Bold), 
            Brushes.Black,
            new RectangleF(new PointF(60.0F, y), ef1), //350.0
            StringFormat.GenericTypographic);

        i += 1;
        sno += 1;
        y += 30;
    }

    e.Graphics.DrawString(
        "------------------------------------------------------------------------------------",
        new Font("Calibri", 10, FontStyle.Bold), 
        Brushes.Black, 
        new Point(0, y));

    e.Graphics.DrawString(
        "Total Amount-:" + TotalAmnt_txt.Text, 
        new Font("Calibri", 10, FontStyle.Bold), 
        Brushes.Black, 
        new Point(150, y+=20));

    e.Graphics.DrawString(
        "------------------------------------------------------------------------------------", 
        new Font("Calibri", 10, FontStyle.Bold), 
        Brushes.Black, 
        new Point(0, y+=20));

    e.Graphics.DrawString(
        "***Care For You ****", 
        new Font("Calibri", 10, FontStyle.Bold), 
        Brushes.Black, 
        new Point(150, y += 20));
