My printer tells me when I need to replace the cartridge and how to obtain a new one sent to my home. It comes within days. It's easy to install and you can even recylce the old one in the same box which comes with a paid UPS label. It couldn't be easier. And even better, the printer cartridge works perfectly.
This is the second set I've bought since I got the printer that uses them. Didn't give 5 stars because I thought the first set would last longer. Print quality and sturdiness of HP cartridges is unequaled.
Had bought a generic toner that totally messed up the inside of our printer. Got it all cleaned out and original toner installed. Seemed to run out sooner than expected. New toner looks perfect. Just hope it lasts.
