On the front panel in VI Properties/Print Options the 'Automatically print front panel every time VI completes execution' is cleared when you exit the VI Properties dialog and return to it. Consequently, you can't get the front panel to print by checking this option.
You're absolutely right. That functionality is faulty. A work around may be to use the operate>>print at completion function. FYI: if you enable this property, the VI Properties/Print Options the 'Automatically print front panel every time VI completes execution' turns black. R&D is aware of both of these problems. Thank you for you're very valuable feedback and post to let us know if there's anything else we can help out with.
