I’ve used HP ink and toner for many years. Wish the cost was lower. It has not been a problem installing new cartridges. The old ones you can recycle for free - just put in the box and attach the label they provide. Drop at UPS or leave out for pick up.
I find the printer and ink effective and clean. I appreciate the recycling feature very much as I am able to send the cartridge back easily instead of adding to the land fill.
