How do you test to see if the LPT1 port is functioning in
hardware?

There are various diagnostics around that use a loopback plug.
Those can be a problem if you cant solder one up.

The other approach is to boot something like a Bart PE CD or
knoppix CD and see if you can print from that. That eliminates
the XP config being screwed up etc.

Would LPT1 fail alone

Yes, that does certainly happen.

or would the serial ports or other devices go with it?

Not usually.

Can it be repaired?

Nope, but it isnt hard to add a parallel port on a
card if you have a free PCI slot. May make more
sense to use a USB/printer port adapter tho.

I'll check Newegg for one of those.

I wouldnt unless you cant print from the knoppix CD.

And I'd also check that the port config hasnt changed in the bios
too.
The port config in BIOS is "Auto". It was unchanged. But I did try
changing it to "Enabled", which just engages legay IRQ7. No change.
So I changed iot back to default. There are no other LPT1 settings in
my BIOS (other than "Disable").

Where does one find a knoppix CD?
