I thought I'd try that on my LinuxCNC system. With or without sudo it does

Linux and move the parallel port cable from the MESA to the back of the machine
it works with that address.
To get the port addresses, you need lspci -v

Interesting. Hadn't thought to use verbose. What's even more interesting is
my parallel port doesn't show up in the list.
Is it actually on the PCI bus? On older motherboards, they
were on a multi-IO chip on, essentially, an internal ISA bus
bridge. These chips usually had 1 parallel, 2 serial,
floppy and game (joystick) port.
