Well, it seems that the system cannot access the scanner when printer is on
port LPT1. I guess I have to use port DOT4.

This gets me back to the original problem of not being able to print after a
while. It seems the DOT4 driver starts to fail, but there are no error
messages other than the status bubble that pops up showing that the document
failed to print.

I've checked the HP site, and it looks like their latest driver is sometime
in 2001, so I have to hope that it is included in XP SP2. Has anyone see or
heard of anthing related to the HP DOT4 port?

Since installing XP SP2, my HP PSC500 printer has stopped working
correctly. After using the printer a few times, and switching user a few
times all attempts to print result in an error dialog indicating the
document failed to print.

The first two times this happened, I rebooted the system and it cleared
the problem.

The last time it happened, I checked the printer properties, and noticed
that the port for the printer was something called "DOT 4_001". I have no
idea what this is, and guessing that maybe it is some virtual port that
did not get updated with the SP2 upgrade, I changed the port to LPT1.

The printer is now working correctly.

Is there a known issue, with this DOT 4_001 printer port?

What is this?

Is there a reason that I should even care? LPT1 seems to be working.
