Inkjet printers are the most common and popular type of printer on the market today. They use specific cartridges which propel ink onto paper, plastic and other substrates. Some color inkjet printers use a single tank for color while others have three different tanks. However, virtually all of them use a separate cartridge for black. What are XL/High-Yield Ink Cartridges? These high-yield HP 61 ink cartridges differ from standard ink by providing more ink per tank. They directly translate to a higher page yield for your HP printer, thus saving you time and money as you print from home or the office. These HP 61XL High-Yield Original Ink Cartridges have a page yield of 480 pages at 5-percent coverage.
