I printed my “underground newspaper” on a Panasonic dot matrix printer back in the 90s. One night I came up with the “innovation” of placing a box over the printer to mute the sound (so my parents wouldn’t hear the printing and admonish me for “wasting” paper and ink, or worse, ask what I was printing). It seemed like a great idea until I noticed the printer was stopping every so often. Concerned, I pulled the box off and was met with a wave of hot air. My young self didn’t realize that dot matrix printers get hot. Apparently the obvious heat sink fins on the print head didn’t register with me.
