打印机如何将自定义纸型设置为默认纸型

[andy7643]

我在打印机中自定义纸型名称是PRINT

我在程序中如下所写

Dim pz As System.Drawing.Printing.PaperSize
Dim pd As New System.Drawing.Printing.PrintDocument
For Each pz In pd.PrinterSettings.PaperSizes
If pz.PaperName = "PRINT" Then
pd.DefaultPageSettings.PaperSize = pz
Exit For
End If
Next


能够执行到pd.DefaultPageSettings.PaperSize = pz这行代码
但是,打印时的默认纸型不是PRINT

请教一下,这是怎么回事?
应该怎么解决这个问题?

我的代码:

Dim ps As New PageSettings
dim pDocument as new PrintDocument
Dim myPaperSize As System.Drawing.Printing.PaperSize

If ps.PrinterSettings.InstalledPrinters.Count > 0 Then '如过系统存在打印机
If ps.PrinterSettings.IsValid = True Then '当前打印机是否有效
For Each myPaperSize In ps.PrinterSettings.PaperSizes '检查该当前打印机是否支持A3的纸张
If myPaperSize.Kind = PaperKind.A3 Then
Exit For
End If
next
If myPaperSize.Kind <> PaperKind.A3 Then '如果当前打印机不支持A3纸张,那么自定义A3大小的纸张
myPaperSize = New System.Drawing.Printing.PaperSize("A3", 1169, 1654)
End If
ps.PaperSize = myPaperSize '设置为指定的纸张
ps.Landscape = False
pDocument.DefaultPageSettings = ps
pDocument.PrinterSettings.PrinterName = ps.PrinterSettings.PrinterName
End If
End If

使用printdcoument只能改变程序运行时的打印机状态
当printdocument对象释放的时候 打印机自动恢复默认设置

应该调用windows api实现

public static bool ChangePrinterSetting(ref PrinterData PS, bool bl)
{
if ((((int)PS.duplex < 1) || ((int)PS.duplex > 3)) && bl )
{
throw new ArgumentOutOfRangeException("nDuplexSetting","nDuplexSetting is incorrect.");
}
else

string PrinterName = GetDefaultPrinterName();
dm = GetPrinterSettings(PrinterName);

上述代码可以实现 纸张大小 打印方向 以及 进纸口的设置

里面用到了一些 结构体 和 枚举
你可以通过查询win32 api手册 获得
