This is very sturdy. older HP LaserJet from 2000. It prints it's own test
pages so is obviously working, but I haven't tried to interface with
Windows 10.
If you can locate the period software you may have more success. It comes
with a network cable (linked to internal hardware adaptor "JetDirect 600N
[J3110A]", and also a USB > parallel cable and power cable.
Might work under a virtual machine environement on a modern OS; comes with a
spare cartridge.
You'll need to confirm by text if offered the goods.
Best
