如何使用winforms中的自定义纸张尺寸进行打印-Java 学习之路

我正在尝试在我的应用程序中打印文档 . 但在不同的打印机上我得到不同的结果 . 这是我的代码：

PaperSize paperSize = new PaperSize("My Envelope", 440, 630);
paperSize.RawKind = (int)PaperKind.Custom;

PrintDocument pd = new PrintDocument();
pd.PrintPage += (sender, args) => Console.Out.WriteLine("Printable Area for printer {0} = {1}", args.PageSettings.PrinterSettings.PrinterName, args.PageSettings.PrintableArea);

pd.DefaultPageSettings.PaperSize = paperSize;
pd.DefaultPageSettings.Landscape = true;
pd.DefaultPageSettings.Margins   = new Margins(60, 40, 20, 20);

Console.Out.WriteLine("My paper size: " + pd.DefaultPageSettings.PaperSize);

PrintDialog printDialog = new PrintDialog(); // to choose printer
printDialog.Document = pd;

if (printDialog.ShowDialog(this) == DialogResult.OK)
{
    // pd.DefaultPageSettings.PaperSize = paperSize; // uncomment to override size from dialog

    Console.Out.WriteLine("Paper size for printer {0} = {1}", printDialog.PrinterSettings.PrinterName, pd.DefaultPageSettings.PaperSize);
    _sptTxtControl.Print(pd);
}

对话框显示我有两台打印机 - 三星和惠普 . 这是这两个的控制台输出：

My paper size: [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Paper size for printer HP LaserJet 1022n = [PaperSize A4 Kind=A4 Height=1169 Width=827]
Printable Area for printer HP LaserJet 1022n = {X=21,83333,Y=15,66667,Width=789,3333,Height=1137,333}

My paper size: [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Paper size for printer Samsung SCX-4x28 Series PCL6 = [PaperSize A4 Kind=A4 Height=1169 Width=827]
Printable Area for printer Samsung SCX-4x28 Series PCL6 = {X=17,33333,Y=17,16667,Width=792,3333,Height=1135,167}

您可以看到对话框正在将大小更改为A4 . 因此，如果你在showdialog之后取消注释，我正在执行paperize . 打印时的输出如下所示：

My paper size: [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Paper size for printer HP LaserJet 1022n = [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Printable Area for printer HP LaserJet 1022n = {X=21,83333,Y=15,66667,Width=789,3333,Height=1137,333}

My paper size: [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Paper size for printer Samsung SCX-4x28 Series PCL6 = [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Printable Area for printer Samsung SCX-4x28 Series PCL6 = {X=16,66667,Y=20,Width=400,1667,Height=589,8333}

您可以看到三星打印机具有良好的可打印区域，而惠普则没有 . 无论我在代码中改变什么，HP总是A4大小（设置originatmargins等）

如果我在打印属性中更改了纸张设置（抱歉波兰语对话框）：

custom paper settings

显示对话框后不更改纸张尺寸，然后HP正在打印所有内容 . 输出看起来像这样：

My paper size: [PaperSize My Envelope Kind=Custom Height=630 Width=440]
Paper size for printer HP LaserJet 1022n = [PaperSize My Envelop Format Kind=Custom Height=630 Width=440]
Printable Area for printer HP LaserJet 1022n = {X=18,66667,Y=16,Width=405,3333,Height=597,3333}

但我不想强迫用户为他的打印机保存自定义大小 . 我也试过用Kyocera打印机 - 它可以工作，但对于其他两台惠普打印机却没有 .

最糟糕的是，Word 2010在两台打印机上都打印出相同尺寸的RTF文档，我不能责怪HP驱动程序 .

有任何想法吗？

PrintDialog关闭后，不要只是设置
```
pd.DefaultPageSettings.PaperSize = paperSize;
```
也尝试设置
```
pd.PrinterSettings.DefaultPageSettings.PaperSize = paperSize;
```
我认为这会照顾它 .

设置

pd.DefaultPageSettings.PaperSize = paperSize;

和

pd.PrinterSettings.DefaultPageSettings.PaperSize = paperSize;

可能不会有效 .

最合适的是选择安装在打印机驱动程序或计算机中的自定义纸张大小，然后设置以下属性

pd.DefaultPageSettings.PaperSize = ExistingPaperSize;
pd.PrinterSettings.PaperSize = ExistingPaperSize;

喜欢这段代码

PrintDocument pd = new PrintDocument();
    pd.PrinterSettings = printdg.PrinterSettings;
    PaperSize RequiredPaperSize = CalculatePaperSize(WIDTH,HEIGHT);
    bool FoundMatchingPaperSize = false;
    for (int index = 0; index < pd.PrinterSettings.PaperSizes.Count; index++)
    {
         if (pd.PrinterSettings.PaperSizes[index].Height == RequiredPaperSize.Height && pd.PrinterSettings.PaperSizes[index].Width == RequiredPaperSize.Width)
          {
              pd.PrinterSettings.DefaultPageSettings.PaperSize = pd.PrinterSettings.PaperSizes[index];
              pd.DefaultPageSettings.PaperSize = pd.PrinterSettings.PaperSizes[index];
              FoundMatchingPaperSize = true;
              break;
           }
    }


    //Method to calculate PaperSize from Centimeter to 1/100 of an inch
 /// Caclulates the paper size
    /// </summary>
    /// <param name="WidthInCentimeters"></param>
    /// <param name="HeightInCentimetres"></param>
    /// <returns></returns>
    public static System.Drawing.Printing.PaperSize CalculatePaperSize(double WidthInCentimeters, 
        double HeightInCentimetres)
    {
        int Width = int.Parse( ( Math.Round ((WidthInCentimeters*0.393701) * 100, 0, MidpointRounding.AwayFromZero) ).ToString() );
        int Height = int.Parse( ( Math.Round ((HeightInCentimetres*0.393701) * 100, 0, MidpointRounding.AwayFromZero) ).ToString() );

        PaperSize NewSize = new PaperSize();
        NewSize.RawKind = (int)PaperKind.Custom;
        NewSize.Width = Width;
        NewSize.Height = Height;
        NewSize.PaperName = "Letter";

        return NewSize;

    }
