本文介绍了使用高级选项打印（纸盒选择，双面打印，装订）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我们有管理打印文档的一个项目。起初，我不知道为什么打印选项不能成立单一的地方。例如打印机纸盒选择作为第一页和其他页面是可以做到的微软Word自动化
We have a project of managing printing documents. At first I wonder why printing options couldn't be set up in single place. For example printer tray selection for first page and for other pages can be done using MS Word automation:
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code打印机纸盒上面指定为整数，因为某些打印机有托盘没有非标准值（我们有这个问题，惠普 - 这是盘codeS描述这里）。所以，我们首先检索什么托盘打印机有，使用code：
In the code above printer tray is specified as integer because some printers have not standart values for trays (we had this issue with HP - it's tray codes described here). So we first retrieve what trays printer have, using code:
var setting = new PrinterSettings();
setting.PrinterName = myPrinterName;
foreach (PaperSource tray in setting.PaperSources)
{
Console.WriteLine("\t{0}: #{1}", tray.SourceName, tray.RawKind);
}
这code工作没有问题。
And this code works with no problems.
但也没办法在这里指定双面打印和装订选项。 复式可以做，用的驱动函数OpenPrinter和SetPrinter ，像描述的，并建议微软以及中的。短纤完全不清楚如果有人知道的方式如何实现这一点，请让我知道。在这个MSDN文章是没用的因为它需要的文件的定制渲染打印。
But there is no way to specify duplex and staple options here. Duplex can be done, using driver functions OpenPrinter and SetPrinter, like described here and recommended by Microsoft as well in this forum thread.Staple is completely unclear and if somebody knows by the way how to implement this, please let me know. Using Stapling enum, like in this MSDN article is useless as it requires custom rendering of the document to print.
我描述的情况，以及如何零部件实施的。 这正常工作对环境的：在Windows Server 2008 R2，微软Office 2010的32倍，打印机的HP LaserJet P2055和理光Nashuatec DSm635。测试与本地和通用PCL6 /的PCL5e驱动程序：双工和预期纸盒选择适用
I described the situation and how parts were implemented. That works fine on our environment: Windows Server 2008 R2, MS Office 2010 x32, Printers HP LaserJet P2055 and Ricoh Nashuatec DSm635. Tested with native and universal PCL6/PCL5e drivers: duplex and tray selection works as expected.
但是部署应用程序客户端后，的，打印机（仅限HP LaserJet 4250和理光Aficio MP C7501）的做印花总是从默认纸盒和双面无。尝试一些不同的驱动程序具有完全相同的结果。
But after deployment the application to client, printers (HP LaserJet 4250 and Ricoh Aficio MP C7501) do printing always from default tray and without duplex. Tried few different drivers with exactly the same result.
在这两种环境中打印机是网络打印机。因此，为了使它们应用于双工设置，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，使本地打印机，建议我在微软的。
In both environments printers are network printers. So to make them apply duplex setting, using printer driver, we needed to install local driver on server and make a local printer, as recommended my Microsoft on this support forum thread.
虽然使用环境和打印机看起来非常相似，一期工程而其他没有。任何帮助将是非常美联社preciated。
Though environments and printers used looks very similar, one works while other do not. Any help will be highly appreciated.
推荐答案
在情况下，其他人需要它，我想出了一个解决方法，基于存储在二进制文件中打印机设置内存块，然后还原它。这个想法在这个博客帖子，但它并没有为我工作时，只需复制粘贴（只工作了一些司机和一些设置，而其他打印选项被忽略）。
In case someone else needs it, I came up with a workaround, based on storing printer settings memory block in a binary file and then restoring it. The idea was described in this blog post, but it didn't work for me when simply copy-pasted (it worked only for some drivers and for some settings while other printing options were ignored).
所以我改过后了一点，所以现在它可以支持我测试过我试过在任何打印机上的所有设置（与兼容的驱动程序）。当然，如果你使用其他打印机司机例如，它不会工作。
So I remade it a bit so that now it can support all settings I've tried on any printer (with compatible driver) I've tested. Of course if you use driver of another printer for example it won't work.
THI方法的缺点是当然，你应该先设置默认打印机，preferences（控制面板）到你所需要的。这并不总是可能的，当然，但至少在某些情况下，它可以帮助
The disadvantage of thi approach is of course that you should first set default printer preferences (in Control Panel) to what you need. That isn't always possible of course, but at least in some cases it can help.
所以测试util的是能够给打印机设置保存到一个文件的完整源$ C $ C，使用指定的设置文件重新加载此文件到打印机并打印文档：
So the full source code of a test util which is capable to store printer settings into a file, load this file again into printer and print a document using the specified settings file:
