Newspapers that are printed on paper or print journalism in general.
E.g.
I read the “dead tree edition” of the Guardian.
Dead tree edition – Edição impressa (de um jornal eletrônico)
Dead tree edition – Slang term used to describe any publication in its printed form when the same publication is available in a paperless version online. In hacker slang terminology, any printed manual or documentation that is freely available online is called treeware.
