I picked up a heavily used one at auction for dirt cheap and it has been awesome. Everything has a driver for it out of the box and it just works. I bought the cheapest generic labels I could find and they print perfectly.
Thermal printers are pretty simple, I’m sure this thing could last enough 20 years.

It depends on your print volume, but at some point the thermal head will start to wear out. On something common and simple like a GK420d this ain't terribly hard to replace, but it's definitely something to keep in mind.
But yeah, I've accumulated a couple ZPL printers from past jobs and they're fantastic. Even hand-writing ZPL is surprisingly pleasant (as far as printer languages go).
