They come across as a traditional press, not a self-publishing press. However, it depends on their contract. If you have to pay back what they have put out before you receive your royalties, then they are a vanity press. As long as you don't have to put out any money, they are considered traditional. The minute the author has to pay, it becomes vanity or self-publishing. I just wanted to clarify that because it appears you are not clear on that.
