打印未从页面顶部边缘开始

我正在尝试打印一些strings using Graphicss.DrawString()。我已将边距设置为printdocument但不从页面的原点开始。我已经设定margins to (0,0,0,0)但不知怎的，它打印在页面顶部边缘下方半厘米处。另一件事是它可以从左边缘打印。

下面是我的代码。

private void button1_Click(object sender, EventArgs e)
    {
        ////PaperSize pkCustomSize1 = new PaperSize("First custom size", 1020, 3517);
        ////printDocument1.DefaultPageSettings.PaperSize = pkCustomSize1;
        printPreviewDialog1.Document = printDocument1;
        printDocument1.PrinterSettings.PrinterName = this.comboBox1.Text;
        Margins margins = new Margins(0, 0, 0, 0);
        printDocument1.PrinterSettings.DefaultPageSettings.Margins = margins;
        printPreviewDialog1.Show();
        printDocument1.Print();
    }

private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        int resX = GetPrinterResolutionX(comboBox1);
        int resY = PrnOpra.GetPrinterResolutionY(comboBox1);
        Graphics g = e.Graphics;

        float scale = resX / ScrnRes;
        Bitmap bm = new Bitmap(367, 1205);
        g.DrawRectangle(new Pen(Color.Black, 0.5F), panel9.Location.X / 2, panel9.Location.Y / 2, panel9.Width, panel9.Height);
        g.DrawImage(bm, 0, 0);
}

代码有什么问题吗？

你必须设置PrintDocument.OriginAtMargins财产要真实地考虑你的利润。

From MSDN http://msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument.originatmargins(v=vs.110).aspx,

When OriginAtMargins is true, the Graphics object location takes into account the PageSettings.Margins property value and the printable area of the page

但从精确边缘进行打印取决于可打印区域，该区域由打印设备的物理限制定义。检查HardMarginX and HardMarginY获取打印机的物理来源。欲了解更多信息，请参阅答案this https://stackoverflow.com/questions/8761633/how-to-find-the-actual-printable-area-printdocument问题。
