Choosing a personal printer for the long haul

The Optimizer writes: "Ask Slashdot: After 16 years of service my laser printer, a NEC Silentwriter 95, is finally wearing its internals out and I need to find a replacement. It's printed over 30,000 pages and survived a half-dozen long-distance moves without giving me any trouble. I believe it's done so well for two reasons. First, it's sturdily built and hails from an era when every fraction of penny didn't have to be cost-cut out of manufacturing, The other reason was its software. Since it supported postscript Level II, it wasn't bound to a specific operating system or hardware platform, so long as a basic postscript level 2 driver was available. A new color laser printer with postscript 3 seems like a logical replacement, and numerous inexpensive printers are available. I'd rather get a smaller, personal-size printer than a heavy workgroup printer. Most of all, I would like it to still be usable and running well with Windows 9, OS X 11, and whatever else we will be using in 2020. Can anyone recommend a brand or series of printers that is built to last and isn't going to be completely dependent on OS specific proprietary drivers?"
