I use my HP printer infrequently enough that every time I booted up my inkjet, I had to put it through a printer head cleaning cycle. I’d be surprised if I got more than 20 sheets of paper for each cartridge do to the wasted ink, and the dang thing malfunctioned frequently even after cleaning (streaks, blots, complaining about missing colors when printing b/w, etc).
After switching to a Brother mono laser, I haven’t had to do any maintenance in 3 years and it’s still on the original toner cart which it came with.
