.NET查找纸盘尺寸

标签: .net printing

有没有办法找到打印机上的所有打印托盘并获取其纸张尺寸,例如

Tray1 = A4
Tray2 = A3
Tray3 = Letter

我可以看到一种方法来使用这样的东西来获取托盘,但它似乎没有纸张尺寸信息。

using (System.Drawing.Printing.PrintDocument doc = new PrintDocument())
{
    foreach (System.Drawing.Printing.PaperSource paperSource in doc.PrinterSettings.PaperSources)
    {
        string trayName = paperSource.SourceName;
    }
}

我想要做的是默认为打印作业选择最佳纸盘。

  1. 您可以使用windows api获取包含打印机纸盒(托盘)的打印机属性: http://msdn.microsoft.com/en-us/library/bb258176(v=office.12).aspx http://www.thedbcommunity.com/index.php?option=com_content&task=view&id=218&Itemid=56

  2. 您可以在ArcObjects SDK 10 Microsoft.NET Framework中使用IPaper类(我不太清楚这是如何工作的) http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//0001000002wn000000

从MSDN检查此代码。你试过吗?可能是您可以将PaperSize名称与托盘名称匹配。

   // Add list of supported paper sizes found on the printer. 
    // The DisplayMember property is used to identify the property that will provide the display string.
    comboPaperSize.DisplayMember = "PaperName";

    PaperSize pkSize;
    for (int i = 0; i < printDoc.PrinterSettings.PaperSizes.Count; i++){
        pkSize = printDoc.PrinterSettings.PaperSizes[i];
        comboPaperSize.Items.Add(pkSize);
    }

    // Create a PaperSize and specify the custom paper size through the constructor and add to combobox.
    PaperSize pkCustomSize1 = new PaperSize("First custom size", 100, 200);

    comboPaperSize.Items.Add(pkCustomSize1);

我认为在C#中更简单的方法是查询PrintDocument打印机设置。

PrintDocument printDoc = new PrintDocument();
PrinterSettings printSettings = printDoc.PrinterSettings;

for (int i=0; i < printSettings.PaperSources.Count; i++)
{
    sTmp += printSettings.PaperSources[i].SourceName;
    sTmp += " : ";
    sTmp += printSettings.PaperSources[i].Kind.ToString();
    sTmp += " : ";
    sTmp += printSettings.PaperSources[i].RawKind.ToString();
    sTmp += "\n";
}

MessageBox.Show(sTmp, "Paper Sources for " + printSettings.PrinterName+ " : " + 
                    printSettings.IsDefaultPrinter.ToString());

如果我寻找&#34;托盘2&#34;在SourceName中并使用RawKind,我得到与上面的GetBinNumber相同的答案,必须导入winspool.drv。

我错过了什么吗?
