Why are printers constantly redesigned with no improvements?

You mean *print* on photo paper. Film is developed. The resulting
negatives (or with some color film, it's positive, not negative) are
printed.

Well, "print" seems a term that got adopted long after I was toying
around with developing film into light-resistant negatives and
developing photo paper into photographs. Maybe it started when other
methods were used to translate negatives to other media, like scanners
for negatives, so "prints" were negatives to paper to differentiate
other means of differently storing negatives. Developer is used on film
following by a fixer, water/wetting bath, and drying. The same process
is used (developer, fixer, wash, dry) for developing (printing)
negatives onto paper. Whether film or paper, they're both use developer
hence they are both developed. I suppose after 50 years the terminology
changed a bit. To me, you developed film, and you developed paper. I
only got into photography because of my dad back around 50+ years ago,
and that lasted only a few years.
