ABSTRACT:
Different print quality modes in a printer such as a color inkjet printer invoke different print rendering options for a particular object to be printed. In an exemplary embodiment, a printer control automatically invokes an error diffusion haltoning technique for photo images whenever high quality mode is designated, and automatically invokes a dither haltoning technique for photo images whenever a normal or fast print mode is designated.
