Understanding printing using Microsoft.Office.Interop.Word

[Andrew Mercer]

Hi,

I need to handle the following scenarios when printing word documents:

<scenario1>
Print document 1 to Printer 1 (auto tray)
Print document 2 to Printer 2 (auto tray)
</scenario1>

<scenario2>
Print document 1 to printer 1 (manual tray)
Print document 2 to printer 1 (auto tray)
</scenario2>

<scenario3>
Print page 1 of document 1 to printer 1 (manual tray)
Print rest of document 1 to printer 1 (auto tray)
</scenario3>

The ...Interop.Word API suggests all scenarios are possible however when I
try scenario3 I get the whole document printing to the same printer.

So if I set

Word.Document.PageSetup.FirstPageTray to the manual tray and
Word.Document.PageSetup.OtherPagesTray to the automatic tray

when I then print the document using Word.PrintOut the whole document is
printed from the manual tray. (The same happens if I try printing Page one
from auto and the rest from manual)

I even tried making two calls two Word.PrintOut as follows:

1. Set the tray for page 1 to manual
2. Call Word.PrintOut (setting the Pages object of the call to Page 1 only)
3. Set the tray for the rest of the document to auto
4. Call Word.PrintOut (setting the Pages object of the call to Page 2 and
above)

I now get the whole document printed from the manual tray and then the whole
document printed from the auto try.

What am I doing wrong?
Am I misunderstanding these objects/settings?

If it helps I can send a sample of my code...

Thanks in advance.
