1.打印预览调用

Font txtFont = new Font("宋体", 12, FontStyle.Regular);//正文字体
newPrint = new Printer(printDataGridView, txtFont, pd, null);
pd.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);

if (printDataGridView.Rows.Count > 0)
{
bool hasMorePage=newPrint.Print(ev.Graphics);
ev.HasMorePages = hasMorePage;
}
else
{
MessageBox.Show("没有需要打印的数据");
}

2.打印预览调用

if (!flag)
{
Font txtFont = new Font("宋体", 12, FontStyle.Regular);//正文字体
newPrint = new Printer(printDataGridView, txtFont, pd, null);
pd.PrintPage -= new PrintPageEventHandler(printDocument_PrintPage);
pd.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);
}
previewDialog.Document = pd;//指向要打印的对象
previewDialog.ShowDialog();//打印预览对话框显示出来

3.打印设置

private void printDialog_Click(object sender, EventArgs e)

pageSetupDialog.Document = pd;
