DefaultPageSettings.Margins 不添加边距

Question

根据 documentation，添加这些代码应该会为打印文档添加边距，但是当我在我的代码中使用它时，我看不到添加任何边距。我对代码的使用是否正确？这是来自 MSDN 的代码：

 printFont = new Font("Arial", 10);
 PrintDocument pd = new PrintDocument(); 
 pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
 pd.PrinterSettings.PrinterName = printer;
 Margins margins = new Margins(100,100,100,100);
 pd.DefaultPageSettings.Margins = margins;
 pd.Print();

这是我的代码：

printDoc = new PrintDocument();
PrinterSettings printSettings = new PrinterSettings();
PaperSize paperSize = new PaperSize("Receipt", 350, 700);

Margins margin = new Margins(2000, 1000, 2000, 1000);
printDoc.DefaultPageSettings.PaperSize = paperSize;

printDoc.PrintPage += new PrintPageEventHandler(pdoc_PrintPage);
PrintPreviewDialog printPreview = new PrintPreviewDialog();
printPreview.Document = printDoc;
DialogResult result = printPreview.ShowDialog();
printDoc.DefaultPageSettings.Margins = margin;
if (result == DialogResult.OK)
{
    printDoc.Print();
}

之所以没有边距影响文档，是因为我没有把OriginAtMargins的值改成true。所以你需要从 PrintDocument() 改变它，像这样：

New printDoc = new PrintDocument();
printDoc.OriginAtMargins = true; //Default is false

DefaultPageSettings.Margins 不添加边距
