Sorry, I wasn't clear. By old hardware, I meant peripherals connected to the computer via serial or USB. We are at a level of performance where running an entire VM as a driver is kind of feasible, if wasteful.
I rarely print anything in any case; which is why replacing this thing is not a really a priority for me. I print something maybe once or twice per year at best at this point. It works and does the job. I can get replacement toner cartridges on Amazon. There are decent non branded ones that are really affordable. I've only ever bought two, I think. I just don't print a lot. If somebody provides something that works indefinitely, I might still be using this thing in another 20 years.
