Cups error - "An error occurred while retrieving the printer list. ": why ?

[Mark Ryden]

Hello,
I have a machine with newly installed  Fedora Core 6 (i386).
I had ran "yum update" on that machine.

When starting kprinter I get the following error message:

An error occurred while retrieving the printer list.

Connection to CUPS server failed.
Check that the CUPS server is correctly installed and running.
Error: the IPP request failed for an unknown reason.

service cups restart does not change anything.
rpm -q cups
cups-1.2.7-1.3.fc6

There is NO firewall running on that machine.

I also ran "tail -f /var/log/cups/error_log" when starting kprinter,
yet I don't see any message in that log when kprinter is starting.

It is a fresh installation of Fedora Core 6. I did NOT yet installed
printers using cups/kprinter on that machine.

I can enter the web interface from a firefox browser by:
  http://127.0.0.1:631 without any erros or problems.
	
Any idea what can cause this error message?

Regards,
Mark

Have you tried restarting CUPS?

service cups restart (in a root terminal)

Oops - I missed your re-start comment.  You say you can get the cups page at 
localhost:631.  Does that find your printer(s)?  How and where are they 
connected?

 Anne,
Thnks.

It does not find any printer since I did not yet add printers;
this is a new computer with a fresh install.However, I do prefer
adding by kprinter thab by cups; and I did it more than once
on other computers in the past. And the printer attached is
not a local printer , but a printer attached to the local network
which has an IP of itself.

Regards,
Mark

OK.  I installed a networked printer with its own IP yesterday, doing it from 
the CUPS interface, and had no problems.  Although I use kprinter a lot, I've 
never used it to install a printer.

Are you sure that the original error was not just saying that the printer list 
doesn't yet exist?

What ever your preferences adding printers to a cups printing systems is
best done through the web interface if you want it to work without
problems. After all you are using cups to do your printing so you might
as well use the cups method for manipulating printing functions.

Hello,

If I start kprinter and ignore the errors I try unsuccesfully to add a printer.
Eventually when starting kprinter I get the same error as before.

This is what I do:
add new printer
Network printer (TCP)
HP laserjet
model: 1015
General Informaton tab (name and location)
Here I enter some text desciption fields.

I reach:
 Error (kprinter) dialog
 clinet-error-bad-request

And when activating kprinter I get again the same error as before:
"an error occurred while retrieving the printer list
connection to the cups server failed. Check that the CUPS server
  is correctly installed and running. Error: the IPP request failed
for an unknown reason."

Regards,
Mark

Mark, just why are you so determined not to use the cups interface?  At worst 
you lose nothing.  At best it will set things up and kprinter will work 
beautifully with it.

It's not clear to me what your setup is;
is the printer attached to your computer,
or are you trying to print on a remote machine?

In any case, I would suggest taking your browser
to <http://127.0.0.1:631> when you should see the CUPS page.
If you don't, there is something wrong with your CUPS setup.
If you do, you could try adding the printer there.

In my experience, it is better to do everything
through this CUPS web-page;
in fact I would start by going to system-config-printer
and removing any printer shown there.
