i have used this extensively and i love this software. you just supply a file and it crunches the numbers and you get an output. there is something called scantailor if you are scanning books yourself. that gives you more contrl over the orientation and margins and ocr and contrast controls. that said, pdfsandwich gives you a miniscule file size which i could not achieve otherwise.
