Here is the press Grandin's employees used to print the Book of Mormon. The letters for the individual pages were placed in the rack then the employees would used those ink mallets to roll the ink onto the letters. Then the paper was laid over them and pressed creating pages 1,3,5,7,9 etc. Then the paper was then flipped over rotated 180 degrees and the next 16 sets of letters were placed in the rack. After the letters were inked the paper was pressed again stamping pages 2,4,6,8,10 etc onto the back side. Then they could be cut and bound into the book.
