.NET查找纸盘大小
是否有办法查找打印机上的所有打印托盘并获取其纸张大小,例如.NET查找纸盘大小,.net,printing,.net,Printing,是否有办法查找打印机上的所有打印托盘并获取其纸张大小,例如 Tray1 = A4 Tray2 = A3 Tray3 = Letter 我可以用这样的方法来获取纸盘,但它似乎没有纸张大小信息 using (System.Drawing.Printing.PrintDocument doc = new PrintDocument()) { foreach (System.Drawing.Printing.PaperSource paperSource in doc.PrinterSetti
Tray1 = A4
Tray2 = A3
Tray3 = Letter
我可以用这样的方法来获取纸盘,但它似乎没有纸张大小信息
using (System.Drawing.Printing.PrintDocument doc = new PrintDocument())
{
foreach (System.Drawing.Printing.PaperSource paperSource in doc.PrinterSettings.PaperSources)
{
string trayName = paperSource.SourceName;
}
}
我想做的是在默认情况下为打印作业选择最好的纸盘

由于受到限制,部分复制自网站,您可以在此处查看完整代码:
从MSDN检查此代码。你试过了吗?可能您可以将纸张尺寸名称与纸盘名称匹配
// 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);
//添加打印机上支持的纸张尺寸列表。
//DisplayMember属性用于标识将提供显示字符串的属性。
comboPaperSize.DisplayMember=“PaperName”;

我认为在C#中更简单的方法是查询打印文档打印机设置
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());
PrintDocument printDoc=新的PrintDocument();
PrinterSettings打印设置=printDoc.PrinterSettings;
