Though inkjet cartridge replacements are widely available, a growing number of consumers are avoiding costly cartridges and instead repeatedly refilling the ink in their old ones. The HP 920XL for the HP Officejet 6500 series of all-in-one printers comes in either black, cyan, magenta or yellow. The 920XL cartridge can be filled with 8 ml of replacement ink, which can print approximately 1,200 pages.
