I tried newspaper for a month and found that I didn't like it much - for the following reasons ...
1. Water dishes could be moved around the tub easier and although they didn't tip they would slosh out onto the paper.
2. Wet paper molds easily
3. Wet paper that dries to the tubs is a pain to remove
4. Paper distributes messes - if the snake releives itself in the corner - it could easily spread over 1/4 of the tub - the snake spends the night sleeping in it's own urine. With other substrates the urine is contained in the corner or filtered to the bottom layer where the snake isn't right on top of it.
5. Spot cleaning - can be done quickly without disturbing the snake - cleaning up newspaper requires removing bowls, hides and snakes to lay down fresh.
6. Most of the snakes crawl under the newspaper anyway - why even have it (LOL)
7. I had a couple of snakes go off feed in protest
8. With the extra work involved with cleaning up paer and with the increasednumber of tubs that needed to be cleaned - my morning cleaning doubled in time with the paper.
But a lot of people have used it successfully for a really long time.
