c# printing a pdf landscape without resorting to 3rd party?

Question

I'm trying to simply print a pdf file in landscape in C# code. Is it simply possible to do without 3rd party software perhaps through a system method? If so, how?

Answer 1

You cannot do this without 3rd party software, Windows does not have built in printing capabilities.
If you do not want to use a paid .NET library to integrate printing in your application, you can use Adobe Reader to print the PDF files from command line, see more details here: Adobe Reader Command Line Reference
