Why is my HP printer using so much ink?
HP, in particular, has received widespread criticism for the high price of its inks. To keep your HP LaserJet from using too much toner, check your settings and adjust them with economy in mind. Adjusting how often you turn your printer off and updating your drivers can also reduce your ink usage.
