I have tested the application and checked its features and options, but the problem is that I don't have a USB Polygraph to attach to my computer, therefore some options were not available. However, I have seen there is no print option which means the only way to print the results is by using Open Interrogation (CTRL + I) and then using Snipping Tools, capture the area with the interrogation and save it as image, then you can use any image viewer to print the results.
You can start Snipping Tools using Start > Search.
