Digital B&W paper is designed to be exposed via lasers and has a very much faster emulsion, it's impractical for enlarger use as the exposure times needed would be impractically short, less than a second even stopped down and it's impossible to control any lamp's output for such a short time, the ramp up time is too long.
They may need handling in total darkness.
Digital colour papers are again faster and have a higher silver content to give increased sensitivity, while it may be possible to use them the colour response is geared to laser exposures.
