HP LaserJet 1200 PCL5
Hp LaseeJet 1200 PS
OKI PCL6 Class driver
Are all listed, though particularly in the case of the OKI I am not sure if these are yours.
My HP BW lasjet is the HP6P which I think is at lease 17 years old and Win 10 did not even bat an eyelid at that
Interestingly I had to hunt for the add a printer by hand (the old method as WIN 10 certainly initially and with my printers just did it all automatically.
I am afraid I am not an expert on virtual machines, though I have used it to revive an old scanner (which I forgot to mention I did have to ditch after 12 years). However it should be possible for you to set up something like ORACLE Virtual machine which is free, then install WIN 10 within that. I useda link from this page
to get my copy of Win 10 for the fresh install. During the install if I remember correctly I just fed in my WIN 7 key. Once you have the virtual machine up and running you should be able to test the printers.
I hope this is helpful but I confess all I know about USB servers has been gleened from Google after typing in your device names.
Edit: the scanner I had to ditch on the upgrade was an Epson 2580 photscanner. It had an excellent negative feeder. Epson refused to release a 64bit driver so for a few years to use the photo bits, I have had to hook it up to an XP machine. I could have kept it and used Vuscan which can drive it from Win 10, but you have to buy that and a new better scanner was almost the same price, though not as good with negatives I suspect. Built in obsolescence as you say.
