I have tried to print pdf by using gswin32 and call it through the process
class

but I can't change the paper orientation....no matter I have set dORIENT1 =
true / false...it is printed as portrait....

Does anyone know how to change the paper orientation in my case?
or having some other idea to print a pdf file in C#?

I have also tried to call AcroRd32.exe throught the process class...but it
can't terminate the acrobat reader automatically....

I really need help from this issue(to automate the printing process of a pdf
file in C#)....thanks a lot

AcroRd32.exe can be controlled via Dynamic Data Exchange. There is no .NET
library for sending DDE poke though, so you'd have to either do this by
issuing shell commands or invoking win32. Either way the available DDE
commands may not be rich enough to handle page orientation.The full Acrobat
viewer has a COM interface that is fairly rich.

I haven't ever tried automating the GS viewer before. Ideally, I think with
GhostScript you'd want to be controlling the GhostScript engine itself, and
not a viewer. You'd have quite fine grained control that way, even if there
is a bit more work.
