I suspect there are command line statements to read from an IO address.

Speed of the parallel port is never a problem because it uses control lines to indicate data is ready to be read.
Your printer sends status data all the time it is operating.

Google says there is aPython extension that you may be able to use to test the board addresses.

I tried to click the link and it says 404 error. I do have an idea though, I could buy/make one of those parallel port interposers that have in-line LEDs tat will blink as signals go through the port, that may work?
Lets try this again! PYthon parallel port extension..
The device you mention sounds a bit like the device I made, Mine also has a set of switches to use the input capability of the parallel port.
I tried the new link and it works for me.
Paul
ok, the link works. I ran the pip install command and it says it got it. Now, how exactly do i use this? ( i have never really done anything with python)
One thing I am guessing may be the problem, is that since I am using a PCIe parallel port, I need inpout32.dll (or inpoutx64.dll) but I am not sure how and where to install them. Do you know what location I need to install inpout32/inpoutx64 to for it to work, and also how to do it? (I have got the files, I just don't know where to put them)
Lastly, what is the device you made? it sounds pretty cool.
I am shocked! IT is still on the web! www.boondog.com/. tutorial on the parallel printer port.
I printed it and made the device back in 2000.
Paul
that actually looks pretty cool, and it seems like something that is actually feasible to program things for (unlike USB which is so confusing a protocol idk what to do) I assume though it wouldn't work very well with a modern PCIe parallel port running windows 10. I also don't know what kind of software would be used with it anymore. But it does sound pretty cool. Like I was thinking you could hook up a motion sensor then have a script running on the PC to wake the PC from sleep when it detects something from the port.
I could also see it being able to act as a hub, so if the PC detects one thing from the port, it could activate something else on the port.
Too bad it probably wouldn't work anymore:(
Anyway, do you have any more ideas on getting my current parallel port situation to work?
I am pretty exhausted for ideas on your parallel port problem.

thats fair, I will try on a pc with a real port and see if it works there, if it does then I can determine it is a problem with my system and tbh I'm probably just missing something really obvious. Thanks for all the help you were able to give, hopefully now I am closer to figuring this thing out.
