I think that'd be a use-case for HPs "ink hostage" (instant ink or something like that), as another commenter put it, program.

If i recall right, i even read somewhere here on HN that someone basically printed full page color prints all day long and HP happily keeps sending him fresh cartridges, which is, at the rate he is paying monthly, a steal...

I guess nothing stops you from ending your membership after you're done with your printouts :)
