It seems you don't have a parallel port at all.
Are you using an old computer with onboard parallel port or a new computer with PCI card?
and I did try using the parallel port tester but i got this
user@linuxcnc:~$ halrun -I -f ptest.hal
Could not open command file 'ptest.hal'
halcmd:
You have to open the Terminal Emulator in the same folder where your parallel port tester files are. For this, right click somewhere inside the folder then "Open Terminal Here".
But with USB to parallel adapter it wouldn't work in anyway. Find a good parallel port PCI card and try again. Avoid any WCH chipsets.
Hi, I find a PCI on Amazon, the chip is Asix AX99100 chip.

The link is here. Will this PCI work? or do you have any recommendation? Thank you.
