Hello, Enrique :)
When I attempt to run the above command, I get the following error:
/var/tmp/cups-snapshot-2004-07-12_14: Unknown host
tar (child): /var/tmp/cups-snapshot-2004-07-12_14\:19\:53.tar.gz: Cannot
open: Input/output error
tar (child): Error is not recoverable: exiting now
I want to help you on this, but I cannot proceed past this point. Any
help you can give me is greatly appreciated :)
Just checked, and a tarball was created - the size was 15.3mb
Midnight Commander said it was corrupted. When I attempt to "gunzip"
it, I get the following error:
gunzip: cups-snapshot-.tar.gz: unexpected end of file
Attempting to browse it in konqueror appears to work fine.
The name of this tarball is:
cups-snapshot-.tar.gz

I didn't use exactly the method that you stated above, but the
appropriate line in "/etc/cups/cupsd.conf" now reads thusly:
LogLevel debug
Will this be sufficient?

I will get on that when I have some time tomorrow :)
Update: Last night, my wife called me at work because she wanted to
print some documents for her Master's degree class. To make a long
story short, the printer had dissapeared again! When I got home, I
started working on it again. I configured it using
"system-config-printer", and all SEEMED to go well. Still, the printer
wasn't there. So, I opened a web browser, and went to
"http://localhost:631/", clicked on "Manage Printers", and I was told
that I had no printer's installed. So, just guessing, I went to
"system-config-services" and checked the CUPS daemon. I was told that
it was running. Again, just guessing, I chose to "Start" the CUPS
daemon. The result: I had our printer back! Tomorrow morning, after I
get off work, I will experiment along those lines again, to see if I can
duplicate the problem. Right now, the printer is working fine.
Thanks again for your continued interest, and if you can help me on the
issues I described at the beginning of this email, I will gladly set up
a cron job and keep as many tarballs of the results as you want (We have
320 gigabytes of harddrive space, so I could go to "debug2" if you
wanted :))
Have a Great Day :)
