Since these are high capacity toner cartridges, I won't have to worry about changing them for a while. Plus, they come with a shipping label so I can return the used cartridges to HP and not have to worry about trying to find a place to recycle them.
I placed my order, received my black ink cartridge in two day! I replaced the old cartridge and put the old one in the box, attached the mailing label that arrived with the new cartridge, sat it in my porch and UPS picked it up the next day to send to recycling center. Easy peas!!
