Abstract: Some examples relate to printing apparatuses and methods. In an example, a roller transfers printing fluid to a substrate. In some examples an electrically grounded roller is positioned proximate the electrically charged roller and guides the substrate. In some examples, the roller is an electrically charged roller. In some examples an electric field is applied and its strength is varied based on a dielectric coefficient of the substrate and/or a thickness of the substrate.
