This is so odd
I posted this before & I have no clue whats happening with this
I have a client that everyone told was crazy & I thought so too until I saw it
Heres the gig
she has a generic pentium 233 system. Nothing ununusal about it, its a standard home brew system.
She has a Lexmark Z11 printer, standard stuff.
If the printer is plugged in to the lpt port the system is dead. no video no post, Dead, nothing. Wont POST
If I disconnect the LPT port from the printer it boots fine
No errors in Windows, everything works.
If you want to print connect the printer & it works just fine
No network, home user, second hand system, it has always done that since she got it
Here is what I have done
checked power, plug the printer straight into the wall, replaced printer cables, replaced power cords, checked the windows sruff but it aint gettting that far
Lexmark graciously replaced the printer, same thing.
If the LPT cable is connected no video no post. The system is dead. The LPT cable has been exchanged
BUT if it is shorting out some how she can plug the printer in & it print & it works fine after the system posts.
I would think that if it is shorting out on the LPT port somehow then it would kill it wen we plug an LPT port into it but that does not happen
I am down to replacing the LPT port & bracket. but I dont think thats the problem.
Ive teched this a lot & everyone says its not possible. An LPT port connection cant killl the video.
I agree. Why does it do it?

Thanks demoked
been there done that
The problem is in the box I think but im not sure.
This is truly weird
It wont post with the LPT cable connected it appers
Why??
Ive changed the settings in the BIOS. Ive been there done that
I have never heard of this before. Neither has lexmark. They replaced the printer

Ive been pondering this & I still have no clue with this!
How is it possible that connecting a printer cable via LPT1 parallell (standard stuff) causes no video no post??
Disconnect the printer on post & its all happy. Plug it in after POST & it works fine.
Plug an lpt cable in before POST, no video no post every time.
How is that possible?

Maybe try using a loopback plug, on port.
And then boot the system.

Hi PC
Not sure about this one, but many years ago I had a crazy problem that had some similarities to this.
The machine was a 386, dos 5, win 3.1, brother printer. If I closed the puter down while the printer was still turned on, the same problem occured, but if the printer was turned off first, all was OK. However when I upgraded to dos 6, the problem disapeared.
Have you tried a different printer driver, is it possible to use different emulation on the printer. Can you duplicate the problem with another puter???
Have fun BF.

Have you tried disabling the onboard printer port, and using an add-on printer port instead? If it still does not work, it could be a bios problem.

PC,
Just a hunch: When you connect the printer cable, I assume it has thumb screws to tighten it down. Maybe when you tighten it down it causes the bracket to contact the mobo or a card next to it shorting it out.
Once the puter boots and finds LPT, the short goes away. Did you try moving the LPT connector to another location, before replacing it?

I am not that good with technical stuff, but have you tried a different printer to see if it is the computer or the printer?
-
PCS,
What happens when the cable is connected to lpt port, but to nothing on the other end? What about when the cable is connected to port and printer, but printer is not powered up? Also, have you tried playing with settings in bios for for that port (Enhanced, ECP, Standard, etc.)?
-
It doesnt matter if the printer is on or off. It doesnt matter if the printer is connected to the other end of the cable
Lexmark replaced the printer. New one does the same thing
I am not tightening the screws in the LPT port down at all. Just placing it in the port.
Tried all the BIOS port settings.
It acts like it is shorting out. I would think that if it were, plugging the priter into the system when the system is running would knock it out but it doesnt. Thats what she has to do to print.
I think im going to replace te LPT port for starters

I had that problem before in where I have to place the card in a certain position so that computer will boot up. I changed the port and it worked fine.

Why? Reasons, Theories, Past experiencies. We need to establish some credibility here.
You may be right, but without something more your statement has the same impact as me saying "Dance around an oak tree at midnight on a full moon, Naked of course. https://discussions.virtualdr.com/ "

I douby seriously if it is the power supply. The system works fine other than this problem.
I tend to agree with BigFred, there is nothing to support that premise. That thought did cross my mind though
Ill work on it sometime next week
