Parallel Port Via m.2

Hi everyone! I'm new to the forum and have a scenario I'm hoping someone here can help me with.

I'm in the design stage of my build. I'm looking for a small form factor passively cooled PC. One solution is the ASRock J4005B-ITX . It's the smallest board I've found with an onboard parallel port.

Mini-ITX is decently small, but if possible, I'd like something even smaller. Intel's NUC looks like a decent solution here and they're available with m.2 PCIe slots. Are there any known issues with connecting one of these to an m.2 slot and then plugging a PCI to parallel card into that? From my understanding, it shouldn't make a difference, but I wanted to get a second opinion before pulling the trigger.

I'll also mention that I intend to use a Gecko G540 with that parallel connection. I've seen that it's also possible to use a Mesa board and interface with LinuxCNC via RJ45, but I haven't really explored that option.

Feedback would be much appreciated, thanks.

Thanks for the input Tommy.

I went with the Mesa 7i92H as the Mesa 7i92M was out of stock. After a bit of reading Ethernet looks like the best option.

I used an ADT link in m.2 E-key to pcie adaptor so I can run a parallel port but i dont think it's working. Is there something i need to do to get it working
I did run power to the adaptor
I am running a Latta Panda Alpha 800. And in the bios it reads Empty /Unknown ???-!!!!!! frustrating
