HP 934XL High Yield Black Original Ink Cartridge (C2P23AE)

There are two basic types of printers: 1) Ink Jet Printers and 2) Laser Printers. Inkjet printers use ink cartridges to precisely ‘spray’ liquid ink on the page, and Laser Printers use toner cartridges to ‘fuse’ toner powder to the page using heat. All printers use a black cartridge which is full of either black ink or black toner, and color printers also have color cartridges which use the three primary colors (cyan, magenta and yellow) to form all the colors of the rainbow.
