.net - 使用高级选项打印(纸盘选择、双面打印、装订)

Question

我们有一个管理打印文件的项目。起初我想知道为什么不能在一个地方设置打印选项。例如 打印机托盘选择第一页和其他页面可以使用 MS Word 自动化 :

var doc = _applicationObject.Documents.OpenNoRepairDialog(FileName: ref sourceFile, ReadOnly: ref readOnly,
                                                                 AddToRecentFiles: ref addToRecentFiles,
                                                                 Visible: ref visible);
doc.PageSetup.FirstPageTray = (WdPaperTray) firstPageTrayCode;
doc.PageSetup.OtherPagesTray = (WdPaperTray) otherPagesTrayCode;
_applicationObject.ActivePrinter = printerPath;
doc.Activate();
_applicationObject.PrintOut(Background: ref backgroundPrint, FileName: sourceFile);
doc.Close(ref saveChanges, ref _missing, ref _missing);

在上面的代码中，打印机托盘被指定为整数，因为某些打印机没有托盘的标准值(我们在 HP 遇到了这个问题 - 它的托盘代码描述为 here)。所以我们首先检索打印机有哪些托盘，使用代码:

var setting = new PrinterSettings();
setting.PrinterName = myPrinterName;
foreach (PaperSource tray in setting.PaperSources)
{
    Console.WriteLine("\t{0}: #{1}", tray.SourceName, tray.RawKind);
}

这段代码没有问题。

但是这里无法指定双面打印和装订选项。 复式 可以使用 驱动程序函数 OpenPrinter 和 SetPrinter ，如所述 here并在 this forum thread 中被 Microsoft 推荐.
订书钉 完全是 不清楚如果有人知道如何实现这一点，请告诉我。使用装订枚举，如 this MSDN article没有用，因为它需要自定义渲染文档才能打印。

我描述了情况以及部分是如何实现的。这在我们的环境中运行良好:Windows Server 2008 R2、MS Office 2010 x32、打印机 HP LaserJet P2055 和 Ricoh Nashuatec DSm635。使用原生和通用 PCL6/PCL5e 驱动程序进行测试:双面打印和托盘选择按预期工作。

但是在将应用程序部署到客户端、打印机(HP LaserJet 4250 和 Ricoh Aficio MP C7501) 始终从默认纸盘进行打印，不使用双面打印 .尝试了几个不同的驱动程序，结果完全相同。

在这两种环境中，打印机都是网络打印机。因此，为了使他们应用双面设置，使用打印机驱动程序，我们需要在服务器上安装本地驱动程序并制作本地打印机，正如我在 this support forum thread 上推荐的 Microsoft .

尽管使用的环境和打印机看起来非常相似，但其中一个可以工作，而另一个则不能。任何帮助将不胜感激。

Answer 1

如果其他人需要它，我想出了一个解决方法，基于将打印机设置内存块存储在二进制文件中，然后恢复它。 this blog post 中描述了这个想法。 ，但是当简单地复制粘贴时它对我不起作用(它仅适用于某些驱动程序和某些设置，而其他打印选项被忽略)。

所以我重新做了一点，现在它可以支持我在我测试过的任何打印机(使用兼容的驱动程序)上尝试过的所有设置。当然，例如，如果您使用另一台打印机的驱动程序，它将无法正常工作。

这种方法的缺点当然是您应该首先将默认打印机首选项(在控制面板中)设置为您需要的。当然，这并不总是可能的，但至少在某些情况下它会有所帮助。

因此，能够将打印机设置存储到文件中的测试工具的完整源代码，再次将此文件加载到打印机并使用指定的设置文件打印文档:

2018-12-04 更新(5.5 年后):这段代码中的 Marshal.StructureToPtr 调用存在一个令人讨厌的罕见问题，今天我终于得到了 that question 的答案(见 Hans Passant 的评论)。我无法验证这是否真的有效，因为我不再从事该项目，但如果您尝试使用此代码，似乎您可能需要应用该修复程序。
