It's also a matter of time and effort. I found what I THOUGHT were proper Win 98SE USB drivers, ("trusted" by Norton, and OK'd by Malwarebytes) but royally trashed the OS, and it ended up faster and easier to just re-install Win 98 than trying to debug it. (But THAT was easy. XP not so much.) but I just didn't want to expend much more time or energy on Win 98. Of course,Win 98 worked perfectly with the H-P Laserjet, but that WAS a Parallel Port. (Remember, I got the LJ in 1987...) And there WAS a simple, inexpensive adapter that let a Win 10 (USB only) machine use the Parallel Port LJ. But there are no adapters for a USB printer to be used by a Parallel Port only computer, at least not "used (and/or abused)" and commanding an arm and both legs. Ten to fifteen years ago, they WERE plentiful, but not now. None of the so-called second source Win 98SE USB drivers I have tried have worked, and while the Win 98 and even XP machines ARE air-gapped from the I'net directly, any "updates" downloaded with another machine can still contain malware, worms, etc. I don't disagree that "old" machines can be, and ARE still usable, but only if they have compatible hardware. And if (actually, when) the hard drive in my Win 98SE machine dies, I doubt there will be any 32 GB or less "IDE" replacements available ANYWHERE.
