Windows security for application

I would like to make a print driver and folder available
for the use of a custom application, but prevent the
users that have access to run that application from being
able to directly access those resources.
For example, printing to the specified print driver is
acceptable within the custom application, but it is not
acceptable for the user to be able to print to it from
Word. Same idea for copying to the specified folder.

Is there any way to accomplish this? Any way to
dynamically change which user account the application is
running under?
Note that user interaction (such as having to type in a
new user name and password) while the custom app is
running is not acceptable.

Please help.
