Most printers come with enough 'demo' ink to print ~10 pages if you are lucky.
The eco tank comes with enough ink to print for years, a free set of ink bottles if your run out in the first 2 years, and comes with more ink than will fit in the printer. I've printed thousands of pages, hundreds in color, and STILL don't have room in the tanks for all the ink that came with the printer. Also it has dies AND pigments, so it does the bright whites (with corect paper) and the inkiest of blacks, on par with the high end laser printers people are talking about above. PLUS the software that comes with it is simple, filled with all the options you need, doesn't have a ton of bloat, and unlike brother, functions well most of the time. I know people swear by brother, but they are cheap and low quality and basic. they serve their purpose fine, but the EPSON Ecotanks do it better. The printhead is a separate part that lasts a long time (its the same print head the super expensive commercial printers, you just get one of them instead of an array that can print an entire page in one pass). The brother printers still have the more expensive printhead/tank combo (but cheaper than the big brands) where you throw out good print heads to replace ink.
I used to have the kodak printer that was similar but the ink on that was lower quality, so was the printer, and the maintenance wasted lots of ink, and did not work well. We had to end up replacing ALL the printheads (its an integrated unit) on the kodak when ONE of them clogged up which was quite often. FWIW this is why most printers have you replace the printheads so often, they clog up if not maintained or designed well.
