A controller is to receive a halftoning job having a number of pages. The controller is to divide each page into a number of sections. A number of halftoning mechanisms correspond in number to the number of sections into which each page is to be divided. Each halftoning mechanism is to perform halftoning on a different section of each page. At any given time, no halftoning mechanism is to perform halftoning on a same page on which any other halftoning mechanism is to currently perform halftoning.
