Ink tank printers print with ink bottles. Are the ink bottles of your printer empty? You can easily replace them with new ink bottles. Which ink bottles you choose depends on the model of your printer. There are ink bottles for HP, Canon, Epson, and Brother, for example. If you print a lot of color documents, a bundle with different colors of ink bottles is useful. With 1 ink bottle, you can print 6000 pages on average, so you're sure that you get enough ink.
