  1. I remember coming across this a while back, I’ve always wanted to try it, but haven’t ever gotten to, maybe I can try using a floppy drive instead of the solenoid seeing as they are super abundant

  2. i was going to build something like that once but with a led pencil and then make a text fort that was copied from my hand writing then i could write papers for school and type them with spell check and other stuff like that you should consider trying something like that i would like to see how it turns out.

  3. Yes, it is. “Matrix” refers to the patterns of dots making up characters. It has nothing to do with pin configuration of the head.

    If it did, even real matrix printers wouldn’t be considered “matrix” printers, because their pins comprise a single, vertical line, not a grid.

  4. Back in the day I had a Silver Reed EXP 400 “Daisy Wheel” printer. I could print flowcharts on it. It did that by using only the “period” to bang out the lines. Of course printing out a 1 page text only resume took 7 min so you can imagine how long it took to print a one page flow chart.
