There are various types of paper: paper with special coating on the surface for printing photos with optimal quality and paper suitable for documents.
Each media type has specific preset settings, such as how ink is used and sprayed, distance from nozzles, etc., so that you can print on that type with optimal image quality.
This allows you to print with the settings best suited for the loaded media type just by selecting that media type.
