I recall a tale from the early days of the automotive industry.
Cadillac was being given condescending advice from European makers about what they were doing wrong, and why the domestics were outselling them.
What they were *missing* was that while Cadillac's sales there were comparable, but lower, than the locals, the euro market was pretty much an afterthought for Cadillac, something like 10% of its own domestic sales.
That is, the smaller foreign market, while worth shipping to, was not worth designing for.
Similarly for Centronics, who pretty much created the dot matrix market, and dominated it until okidata & friends ate its lunch.
But those Centronics 730s didn't have microcontrollers or microprocessors, and I doubt that the later 737 & 739 did, either. Half-stepping the printer head just wasn't an issue.
I don't remember whether the 730 lacked lower case, or just descenders for them (yes, descenders were rare on dot matrix in the 70s).
I think that the 730 was about $1k until the 737 rolled around at the same price (and with descenders), with the 730 dropping to $700, but it's been a while.
[and as a sidetone, Cadillac wasn't nearly as expensive as others at its luxury point back then. It was significantly more expensive than, say, Ford or Chevy, but with the luxury of brands a multiple of its price. {more reliable and better engineered, too--Cadillacs were the choice for regularly scheduled delivery/passenger runs in the desert!}]
