My grandma used an original HP Deskjet (from 1988) on a Pentium one computer running Wordstar and Wordperfect 5 on MSDOS until she moved to an elderly home in 2015. My dad replaced the rubber rolls on the printer a few times, and I think he had to refill the old cartridges with 3rd party ink, but other than that it still worked perfectly. No idea what happened to it though... I suspect finding replacement parts for the things that wear out has become close to impossible, but I doubt that thing was broken in any other way.
