Scanning the photographic film negative instead of the printed photo will normally produce a better quality digital image. The main reason is because scanning the printed photo is making a copy of a copy. If the negative film appears to be in worse condition than the printed photo, then scanning the printed photo would probably be better.
Below are scans of the same photograph, but one was created from the printed photo and the other from 35mm negative film. The printed photo was scanned at 600ppi and the 35mm negative film was scanned at 2400ppi. Due to the physical size difference between the printed photo image and the 35mm negative film image, these 2 resolutions (600ppi and 2400ppi) are comparable.
The 2 photos show the visual difference in quality between the scanned printed photo and the scanned 35mm negative film. Farther down the page is a zoomed in comparison.
