In one example, a printer includes a printer housing, a photoconductor to apply toner to a print substrate, a developer to apply toner to the photoconductor, a light source to expose parts of the photoconductor to light, and a toner container to supply toner to the developer. The toner container housing is integrated into the printer housing as a load bearing structure or as an exterior feature, and/or the light source is integrated into the toner container as a single sub-assembly within the printer housing.
