I sincerely hope that folks more knowledgeable about computers than I
can shed a little light on this problem...

I'm still using the HP Deskjet 600C printer I've had since 1999. Lately,
it's
been streaking quite a bit, indicating it requires a cleaning. So, I went
and
purchased the HP Cleaning Kit, which contained a CD-ROM disc and 5 sheets
of special cleaning paper.

When I insert the disc, I've been able to follow the screens up to a point.
However, when I get to the menu where I indicate the printer model I'm
using and the port where it's connected (LPT1), I receive an error message
telling me it cannot detect the printer and to select a different port.

It's definately hooked up to LPT1. I have had no problems printing out a
page.
However, I cannot run this cleaner because it refuses to acknowlege the
printer's existence.

I've gone to the HP website and checked to see if I needed an updated
driver.
I'm told that what I'm using is the latest.

Where am I missing the boat? Many thanks in advance to anyone who can
help out in this mission.
