Cook bacon in a pan over medium heat (or in the oven at 325 for about 20 minutes) until crisp. Remove to a paper towel-lined plate to drain grease and cool down a bit.
While the bacon is cooling. turn your panini press.
Spread one tablespoon of peach preserves each onto 4 of your slices of bread. Top with 2 slices of bacon (I broke mine in half, so I had 4 pieces to line along my bread), 3 or 4 slices of brie, and 4 or 5 peach slices. Then top with the remaining bread slices.
Place in the panini press, lock it down, and allow panini to cook until nicely browned and the brie is good and melty. Remove to plates or a cutting board and slice in half diagonally - the devour!!
