What is it that you are trying to achieve?
There are some examples in our knowledgebase (searchable from the Search field above) or on the Net Express forum. if you look for terms like "print" then you will find some specific examples of how to perform various tasks but I could not find a generic example that showed how to use all of the functionality.
Printing in .NET can also be achieved by using the PrintDocument and other classes.
I tried to create a program that would demonstrate how to get the Printer name and properties from the PrintDialog and then set them using PC_PRINTER_DEFAULT_NAME and PC_PRINTER_DEFAULT_PROPERTIES so that they would work with printer redirection and I discovered that some of the properties such as print orientation are being ignored so I wrote this up as a bug.
I am including the program here anyways. The following will attempt to set the orientation and the number of copies. You must set the tunable printer_redirection on order for this to work properly.
