推荐答案

面板控制它自己

所以，使用此命令

panel is control it self
so, use this command

PrintDialog myPrintDialog = new PrintDialog();
System.Drawing.Bitmap memoryImage = new System.Drawing.Bitmap(panel1.Width, panel1.Height);
panel1.DrawToBitmap(memoryImage, panel1.ClientRectangle);
if (myPrintDialog.ShowDialog() == DialogResult.OK)
{
    System.Drawing.Printing.PrinterSettings values;
    values = myPrintDialog.PrinterSettings;
    myPrintDialog.Document = printDocument1;
    printDocument1.PrintController = new StandardPrintController();
    printDocument1.Print();
}
printDocument1.Dispose();

或比例图片，如果它不适合页面

or scale image if it''s not fit into page

private void panel1_Click(object sender, EventArgs e)
        {
            PrintDialog myPrintDialog = new PrintDialog();
            memoryImage = new System.Drawing.Bitmap(panel1.Width, panel1.Height);

//scaling into small size
            memoryImage.SetResolution(150, 150);
            panel1.DrawToBitmap(memoryImage, panel1.ClientRectangle);
            memoryImage.Save("E:/a.bmp");
            if (myPrintDialog.ShowDialog() == DialogResult.OK)
            {
                System.Drawing.Printing.PrinterSettings values;
                values = myPrintDialog.PrinterSettings;
           
                myPrintDialog.PrinterSettings.DefaultPageSettings.Landscape = true;
                printDocument1.DefaultPageSettings = myPrintDialog.PrinterSettings.DefaultPageSettings;

                myPrintDialog.Document = printDocument1;
                printDocument1.PrintController = new StandardPrintController();
                printDocument1.Print();


            }
            printDocument1.Dispose();
        }

        private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
        {
            SizeF sz = new SizeF(e.PageBounds.Width - e.MarginBounds.Width, e.PageBounds.Height - e.MarginBounds.Height);
            PointF p = new PointF((sz.Width) / 70, (sz.Height) / 70);
            e.Graphics.DrawImage(memoryImage, p);
        }

注意：我试图在Papersize中打印是A5
