打印未从页面的顶部边缘开始

Question

我正在尝试使用Graphicss.DrawString() 打印一些strings。我已将边距设置为printdocument，但不是从页面的原点开始。我已将margins 设置为(0,0,0,0)，但它以某种方式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？

您必须将 PrintDocument.OriginAtMargins 属性设置为 true 才能考虑您的边距。

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

但从精确边缘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 和HardMarginY 以获取打印机的物理来源。更多信息请参考this问题的答案。
