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。

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
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?
