HP cartridges come in different models and specifications. HP cartridges may be for ink
jet printers or for laser jet printers. Both models of HP cartridges are refillable.
Refilling HP cartridges would be the wiser option because it is more
economical than buying new cartridges with ink. New ink cartridges though do not dry-up easily as compared to refilled cartridges. This may be due to some chemical properties of ink. Some ink refill station may have inferior quality of ink. It is thus advisable to consult the authorized HP dealers in refilling
ink cartridges. HP also has a program of recycling its cartridges to help the global campaign of environmental protection.
