I have the HP Deskjet 1010. It's an older printer, and after seeing how hard printer ink is to get for it, I may have to upgrade soon.
I thought about purchasing ink online, but I did not.
Mine is straightforward. Turn printer on. Open front door. Pull printer cartridge down and pull towards you to remove. Then, insert new cartridge in same spot and press upwards to click into place.
My printer used to ask for a verification print, but it did not today. Must be a software issue. Oh, well. It prints.
