The last major typewriter manufacturing facility closed in 2011. Typewriters are rumored to still be manufactured by one or two small companies but it’s essentially a dead technology. We spent one summer looking (successfully) for a manual typewriter requested by an Italian monk. How long he’l be able to get ribbons for it is anyone’s guess.
Yes I imagine the big problem is parts and supplies. Kind of like old appliances. It’s a shame because those old typewriters were built to last. They were work horses. And with apologies to all high tech people, I maintain that typewriters type envelopes and labels a lot better and faster than prepping them on a computer and printing them out.
