打印不会从页面的上边缘开始

Question

我正在尝试打印一些strings Graphicss.DrawString().我已设置边距printdocument但不是从页面的原点开始.我已margins到(0,0,0,0),但不知它打印页面的顶部边缘低于一半厘米.另一件事是它可以从左边缘打印.

以下是我的代码.

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？

您必须将该PrintDocument.OriginAtMargins属性设置为true才能考虑边距.

来自MSDN,

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

但是从精确边缘打印取决于可打印区域,该可打印区域由打印设备的物理限制来定义.检查HardMarginX并HardMarginY获取打印机的物理原点.有关更多信息,请参阅此问题的答案.
