If you have a basically bulletproof monochrome HP 4000 series or similar that has cheap cartridges that last 5-10k pages, easy/cheap maintenance (a whole new set of rubber rollers costs $30-50, and is basically the only part that wears out), and a low printing volume, I can totally see having a printer for 20 years.

Same here. Happy HP 4000 owner. 1999 technology and it never fails. Maybe get a paper jam once a year. The only trouble I have is the plastic is getting kind of brittle and little odds and ends snap off but the printer still functions exactly the way it did 20 years ago.

A sneaky issue with these printers though is that they use an excessive amount of power even when doing nothing.
