Everything I have found so far has not worked for me. I have a Crystal Report with header, details and footer. The details section is a text that occupies two pages. In the report preview everything is fine. If I export the report to pdf, an empty page is inserted at the end. I tried to modify the margins and the settings of the sections but without getting anything. A very strange thing is that the blank page shows the writing: Pages 3 of 2 (absurd)
After days of useless attempts, I solved by printing only the full pages.
