A:Answer Well, it really depends on cartridge size and ink tank size. Buying only ink vs. whole cartridge each time make printing cheaper, but you need to "maintain flow" (print something at least once in couple weeks). If you leave your printer without work for a long period, ink may harden inside printing heads, and in case of cartridges you can just buy a new set, but with CISS (liquid) you might end up buying a new printer.
I would say, that in general CISS (liquid) are more for people who print a lot and regularly, and cartridges are more for occasional printer users.
