Class>>VI Server >>Application>>Printing............ No one uses it but, it is there!
I used it several times before scripting was a thing. I didn't have any other way to programatically get images of source code to be put into a document for archival or review. I also had LabVIEW code in my senior thesis in college and I used it then to get images of the block diagram without having to open every VI and Print screen.
But Jeff is right, it was never a feature used very often.
