I have some problems with CUPS on SuSE 8.2. Maybe here is a cUPS expert who
can help.

I configured the printer (HP950C) with Yast 2. This seems to work without a
problem and I can print the test page.

But if I now try to print from a KDE program, a dialog "Print status" occurs
with the following information (translated from german):

Document ... printing
Initializing ...

There is a "Close button" in this dialog. If I press this button, the
program freezes. If I don?t press the button, the dialog closes after some
minutes and the program works. If I choose printer "high_gray" printing
works after the dialog is closed, if I choose "normal" nothing is printed.
On the CUPS Web-Interface the job printed with "hig_gray" is correctly
marked as "completed" and the job printed with "normal" is marked as
"aborted".

If I try to use the printer page in the KDE control center and if I select a
printer on this page, the control center freezes before it can show the
interface icon.

After this, I tried the printer overview in the CUPS Web-Interface. This
overview works. But If I select a single printer (e.g. draft) the browser
shows a timeout warning as follows (translated from german):

Loading of http://localhost:631/printers/draft failed:

Timeout on server.
Connection to localhost on port 631

All other pages on the CUPS Web-Interface seems to work including the job
overview page.

This seems the reason for my problems. Unfortunally CUPS don't write
anything useful when the problems above occur to its error_log, even if I
choose debug2.

Printing with lpr and high_gray seems to work fine without any waiting time.

I reinstalled the printers and CUPS but this didn't help.

The problems occurs if I connect the printer with USB or a longshine lpd
print server.

But on my desktop computer with the same SuSE version and the same printer
are no problems, all works perfectly, including the KDE control center, the
CUPS Web-Interface and the printer "normal".

Anyone have a idea how to solve this problem?

.... on the desktop machine, are you using parallel or usb?

Currently I'm using the print server (Longshine DSL router with print
server) over ethernet. I have tested printing over USB and the print server
on the desktop, both works without problems.

On the laptop I have also tested printing over USB and the print server.
Both make the same problems, as I described.

I solved the problem. The IP-Address in /etc/hosts was wrong. When CUPS
tried to access the printer configuration it fails.

That means: http://localhost:631/printers/draft works, but
http://hostname:631/printers/draft didn't worked. That causes also the
problems wirh KDE.

After I corrected /etc/hosts all works fine.
