I have an adult male corn snake, Figment, (he's hypo-lavender), and he's been on printless newspaper his whole life.
He does great.
Eats like a P-I-G and sheds great. I have him in a boaphile tank and it's just so easy clean up the paper. However, that tanks holds humidity real well.
If it's a glass tank, you might need to spray water when your snake is going to shed to up humidity. Otherwise, NO PROBLEMS with paper substrate. Corns, at least, do not need crazy humidity and as long as you give adequate hides (since borrowing isn't an option), the snake should do fine.
