The idiom "a lot of fine print" means there is a large amount of detailed information presented in very small writing, often found at the bottom of contracts or other legal documents. It refers to any situation where there are many conditions, restrictions, or details that are written in such tiny letters as to be difficult to read and understand. The phrase implies that these fine print contains important clauses that may have a significant impact on the agreement or transaction, but they are often overlooked by people who don't take the time to carefully read them before signing.
