D76 is used to develop film, but it can also be used to develop photographic paper (D76 is generally not used).

D72 is specially used for developing photographic paper. When d76 is used to develop photographic paper, the particles are thicker than d72. If you want to reduce particles, you can dilute d76 according to 1: 1 and then extend the development time.
