The HP Deskjet 500C originally sold for $1095 as the first inkjet color printer. CYM printing meant the printer needed to replace cartridges 3 at a time. The printer had to use all three inks to approximate black. More recent printers added a black cartridge to meet consumer demands for better print quality..
Canon and HP are the main large corporate titans in the printer business. Both sell larger machines for corporates needs addition to mass market needs.
With small print cartridges this will lead to the printer exhausting its ink supply in 3-6 months. Larger cartridges survive longer. Ink refills are expensive pressuring the industry towards larger print tanks which could be marketed as being able to print larger volumes of documents.
