Laser and LED printers use dry toner – they should last a lifetime, as long as they are kept at a normal room temperature.
Solid Ink should also last as long, provided it is kept inside its sealed wrapper.
Inkjet cartridges, on the other hand, have a shelf life due to the liquid ink deteriorating over time. Also, when they are opened, the heads tend to dry up if only used occasionally – frequent cleaning cycles may be necessary to prevent this, though that does use up a small amount of ink.
On some occasions, the Inkjet cartridge heads can dry up to the point where they cannot be cleaned and, therefore, require a replacement.
Do consumables dry up?
