There's very little point in messing around with two PC floppies these days - just use a KryoFlux (or a Catweasel if you can find one). You'll get better results, and it's a lot more convenient.
Parallel ports will not work with Amiga disks - the disk controllers are on the device, and they can't read Amiga floppies at all.
CrossDOS will happily read 1.44MB floppies, or you can use PC-Task with its own handler. Not terribly fast, but it works!
