You can use LabVIEW to document and print VIs.
Document a VI to record information about the block diagram and/or the front panel at any stage of development.
Some options for printing VIs are more appropriate for printing information about VIs, and others are more appropriate for reporting the data and results the VIs generate. Several factors affect which printing method you use, including if you want to print manually or programmatically, how many options you need for the report format, if you need the functionality in the stand-alone applications you build, and on which platforms you run the VIs.
