Print papers are far slower and much lower in contrast range than film, which is why the negative must be developed to fit the paper rather than the other way round. They are usually blue-sensitive only, permitting safelight handling, and are made in warm-tone and neutral emulsions that visibly change the character of the final print.
Examples in practice
The same negative printed on a warm-tone chlorobromide paper and a neutral bromide paper yields two quite different pictures.
