What's the difference between pressing and printing flowers?

They both are flat.
They both are pressed.
They both are being taken care.
They both have color that eventually fades away.
They both are imprinted. 

    When I was a child my grandmother taught me how to press flowers. I took my childhood memories of those moments and encapsulated it into three boxes in three different mediums: text, images and real flowers.

Mediums: dry-point, scrolled book and pressed flowers
Dimensions: an each box 3"(length) x 2"(height) x 1"(breadth)
