That's like saying 1 dot matrix printer is 1 dot matrix printer. It still doesn't detract from the fact it's damn near worthless in both utility and resale price from when it was originally purchased.
They are awesome parts sources for 3D printers, especially the wide carriage ones.
I will agree there. But as per their function and utility as a unit, they are a far cry from 2+ decades ago. But damn, at the time...dot matrix printers was like wizzardry compared to typewriters lol.
