打印dataGridView

第一步：向窗体拖放三个打印组件printDialog1，printPreviewDialog1，printDocument1；
第二步：注册打印的button事件  
private void button1_Click(object sender, EventArgs e)
  {
  printDialog1.ShowDialog();
  printPreviewDialog1.Document = this.printDocument1;
  printPreviewDialog1.ShowDialog();
  }
第三步：注册printDocument1组件的打印　PrintPage事件。
  private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
  {
  int x = 0; //开始打印位置
  int y = 0;  
  for (int i = 0; i < dataGridView1.Rows.Count; i++)
  {

  for (int j = 0; j < dataGridView1.Columns.Count; j++)
  {

  try
  {
  Font drawFont = new Font("Arial", 10); //字体设置
  e.Graphics.DrawString(dataGridView1.Rows[i].Cells[j].Value.ToString(), drawFont,Brushes.Blue,x,y);
  x = x + 60; //宽度设置
  }
  catch(Exception){} //当遇到空值是发生。
  }
  x = 0;
  y += 40; //行高
  }
  }
