> You probably print a lot if an ink cartridge service is cost effective for you.
HP's service bills by page count, not by ink usage. So as you increase print volume, the unit economics get worse. I use it for photo print applications that don't require high quality or a print size greater than US letter. For that, which maximizes the ink-to-paper ratio, it works out splendidly.
(I suspect it works out as well for HP as for me, because the program also requires spent cartridges be returned in prepaid packaging. This allows them, and their expensively precision-manufactured print heads, to be refilled and reused.)
