When one prints a folder how do stop the contents of subfolders from being listed?
Unless you're using Flat View (and thus can see the contents of sub-folders in the lister) I don't think the Print Folder command will include sub-folder contents in the first place. Doesn't seem to for me anyway.
Along the lines of what Nudel just said... there's a specific 'FlatView' checkbox in the PrintFolder dialog... deselect it.
