But there has been at least 1 good printer, and HP made it: - https://en.m.wikipedia.org/wiki/HP_LaserJet_5
Also, 9-pin dot matrix printers were workhorses.
At home I have an Epson ET-M3170, it's not a laser but one of those epson thing where you don't have cartride but just empty bottles of ink into a tank when it's empty, and it works great too (it's much slower, but then again it's a lot cheaper).
It's mostly inkjet printers that are always terrible.
Those things are tanks. Perform a maintenance kit on one of those, and it's good for another 150k pages no problem. The main thing that needs attention is the rubber feet that pick up the paper get dry. Some rubber rejuvenator on a q-tip goes a long way.
I have a 4050 for home, and I have no reason to doubt its future longevity. :-)
The firmware, though, is ancient (telnet, and a web interface that requires IE 5 IIRC). Now if there was open source firmware for these things...
They also made some great RPN calculators.
Then they killed off the calc division, not because it wasn't profitable, but because it wasn't as profitable as ink. Years later they decided to upgrade the calculator (TI had won the market in the meantime), instead of doing something innovative they bought a new arm chip and ran an emulator of the old chip and used the old software stack with minimum polish under the emulator. Not surprisingly Texas Instruments laughed all the way to the bank.
Their laser printers were starved as well, again not as profitable as selling ink for ink jets. So the print engine was killed off and now uses the same print engine that you get in a Dell printer. Which was sad, they weren't nearly as durable.
It was sad to watch
