I tried making my dot-matrix printer do braille by using very thin paper

I tried making my dot-matrix printer do braille by using very thin paper and repeating the same patterns over and over again without ink back in the early 90s. It worked sort of. I was gonna make it into a 3D printer too by using a resin based ink and having the platen move backwards with a stepper motor but then I realized I hated soldering.
