• The Deskjet 4160 from Hewlett-Packard is an ink-jet printer. It can print documents at up to 30 pages per minute, as well as handle photo printing with an optional photo ink cartridge. Since the printer uses ink cartridges, it will run out of black and color ink over time and need a new replacement cartridge. If you are unsure how much ink you have left, you can use your computer's built-in printer tools to display the estimated ink levels.
