This is a strange one, so I turn to the collective wisdom of the forum:
I have an elderly DELL Optiplex 390 ‘Small Form Factor PC, for which I have just purchased a StarTech PEX1P/PEX1LP PCIe parallel port adapter.
So far, so good … I’ve even sorted out Win 10 drivers for it.
The problem is mechanical [!] … the half-height card will only fit into the machine if l remove its mounting plate. This is clearly not a practical solution.
I am too blind or daft [probably both] to see exactly where the obstruction lies, So I’m hoping someone might have encountered the problem before.
