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);
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);
}
And this code works with no problems.
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.
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.
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.
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.
Though environments and printers used looks very similar, one works while other do not. Any help will be highly appreciated.

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).
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.
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.
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:
UPDATE 2018-12-04 (in 5,5 years): There was a nasty rare problem with Marshal.StructureToPtr call in this code and today I finally got an answer to that question (see comment from Hans Passant). I'm not able to verify if that actually works since I no longer work on that project, but it seems you may need to apply that fix if you try using this code.
