That has been said for the last 20 years, it is still here and still works properly.

Well, No new PC has one. Worse, new PCs are mostly laptops these days. They do not have any ports except USB.

I am not sure what I will do next.

Few new pcs have them. But I think it is still possible to find one with a parallel port. True, no laptops do, but you don't really want one of those for a cnc anyway.

Ethernet is very nice, check the Mesa 7i92 and while you're at it, also check the Mesa 5i25 for PCI or 6i25 for PCI-E.
They are very cheap and very flexible and extremely fast, and they have the best support.

I'm a little confused about your statement "new PCs are mostly laptops these days", could you expand on that a bit more.

Well, my Dell technician told me that 90% of all new computers sold by Dell at this stage are Laptops.

I have not seen any proper desktop machines in the shops either. Closest is a screen with PC built in.

But of course you wanted to make a different point and will hopefully do so in your next reply.

Just must be your area.
Plenty of ex corporate machines available and are worth a look at.

If you want small the Odoird H2+ would make a good candidate.

Or this might be a candidate if all you can get is a Laptop with USB.

Or ditch Linuxcnc and jump on the Mach bandwagon.
