To get the most out of your printer ink, be sure to set the printer settings to the lowest necessary quality. This will make the printed paper slightly lower in terms of quality, but will save you money and ink in the long run. Also, unless you need to, try printing in black and white instead of in color, since this will also save you money. Once your cartridge is dry, be sure to recycle it or dispose of it carefully. There are chemicals that damage the environment in printer cartridges, but fortunately many office centers will recycle printer ink.
