What makes for a good DPI also depends on viewing distance. A glossy magazine might have up to 600DPI, but a poster you're going to view from 10ft away - then 72DPI is probably more than enough.
Also is your printing program keeping the DPI, or is it scaling stuff to fit on the page? (In which case it's just using overall resolution and ignoring scaling that affects the DPI.) If you're using camera software it could be shuffling around the actual DPI using EXIF data embedded in the .jpg even. (Some cameras have a generic web-ready 72DPI in the regular .jpg data fields, but add more proprietary info than what's normally showed in properties.)
For cameras, DPI on output files means diddly. You're going to want overall resolution. (Not much point if a camera is 640x480, but saves at 300DPI that's a postage stamp.) After resolution (or perhaps before it) the important factors are color trueness and noise.
