Missing LPT1 port

For some reason unknown to me, Windows 95 no longer acknowledges that I have a LPT1 port. As you might imagine, this make printing from Windows 95 somewhat inconvenient.
 
How do I know it's missing? Device manager refuses to list it in the "Ports (COM and LPT)" section of its output. The printer I have connected to LPT1 no longer works through Win 95, though I can still get it to print when I'm using DOS.

What would I like? I'd like someone to tell me how I can persuade Windows 95 that I have a working LPT1 port so I can again send output to it. It would be extra nice if the solution did not involve a Windows 95 re-install. :-)

I am pretty sure this is caused by a hardware conflict in your machine, I mean a conflict between your LPT1 port and a card in your PC (soundcard, etc.) using the sale IRQ or adress space.
The most probable conflicy would be between your sound card and your printer port : sound card often use the same interrupts (IRQ) as LPT1. The fact that your printer works under DOS confirms your LPT1 port is ok, "hardware speaking".

So try to go in the Control Panel -> System, and change the IRQ used by your sound card. You'll have to restart Windows95 for the change to take effect. If this doesn't work, try to remember what hardware you added recently or what changes you made to your system, and try in this direction ...

First thing to check would be the printer port setting in your CMOS (this is assuming that your ports are built on the motherboard) make sure it is enabled with the right address.
If this is fine then remove all additional cards from the computer .
Go to device manager remove the serial ports or any other ports.
Then restart the computer. Your ports should now be recognised and re-installed. Then re-insert your sound card etc. making sure that nothing is using interrupt 7.
