最近评论问题比较多，这是几年前得代码了，今天正好有时间我重新整理了下代码把源码Demo发上来给大家看看互相学习。

有问题随时交流。没有积分得私信我发你。

//调用GridPrinter

首先添加一个printDocument控件并激活其printDocument_PrintPage事件写：

实例化类GridPrinter gridPrinter;

private void printDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
            bool more = gridPrinter.DrawDataGridView(e.Graphics);
            if (more == true)
                e.HasMorePages = true;
}

//定义一个bool方法

private bool InitializePrinting()
{
            PrintDialog printDialog = new PrintDialog();
            //printDialog.AllowCurrentPage = true;
            //printDialog.AllowPrintToFile = true;
            //printDialog.AllowSelection = true;
            //printDialog.AllowSomePages = true;
            //printDialog.PrintToFile = true;
            //printDialog.ShowHelp = true;
            //printDialog.ShowNetwork = true;

            if (printDialog.ShowDialog() != DialogResult.OK)
                return false;

            printDocument.DocumentName = "人员基本信息";
            printDocument.PrinterSettings = printDialog.PrinterSettings;
            printDocument.DefaultPageSettings =   printDialog.PrinterSettings.DefaultPageSettings;
            printDocument.DefaultPageSettings.Margins = new Margins(40, 40, 40, 40);

            gridPrinter = new GridPrinter(dataGridView1, printDocument, true, true, "人员基本信息", new Font("黑体", 18, FontStyle.Bold, GraphicsUnit.Point), Color.Blue, true);
            return true;
}

//打印按钮中添加如下代码：

if (InitializePrinting())
{
                PrintPreviewDialog printPreviewDialog = new PrintPreviewDialog();
                printPreviewDialog.Document = printDocument;
                printPreviewDialog.ShowDialog();
}

//运行效果如图所示：

点确定按钮后如图所示：
