The software allows you to export the reports to PDF using the Reports button. You can't just click and then save the PDF file, because the data needs to be configured prior to this operation. After you click the Reports button, make sure to select valid settings that will be displayed within the PDF file. After this process, the application will give you the possibility to save as PDF format. For more information, I recommend downloading the official PDF User Guide file. Open the file, press CTRL+F and type Export. It should take you directly to the Reports section.
