printDocument1.PrinterSettings.Copies = 2;
printDocument1.Print();
}

    private void printDocument1\_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        e.PageSettings.PrinterSettings.Copies = 2;
       
        e.Graphics.DrawString("Test Print", new Font("Tahoma", 14, System.Drawing.FontStyle.Bold), Brushes.Black, 50, 50);

So use the CellContentClick event and in the body of this event for getting data of row that user clicked on the button of same row use below code : dataGridView1.Rows[e.RowIndex].Cells[i].Value.ToString();
