I printed some of my homework in 1978-1980 on a Teletype Model 33 ASR. Some teachers liked it (compared to handwriting), some thought I was cheating, "having a computer do my homework." Had to explain that it was just an "expensive typewriter."
From 1980, I used dot matrix printers instead. Somewhat different vibe. Still got mixed reactions from teachers in high school and first two years of college.
Started using DEC LN01 laser printer in 1984. No complaints from teachers.
