--- Comment #1 from Johannes Meixner 2010-06-01 07:40:10 UTC ---
The Canon web site e.g. the German product specification at
http://www.canon.de/For_Home/Product_Finder/Printers/Laser/i-SENSYS_LBP2900B...
shows that the LBP2900/LBP2900B devices understand only
the proprietary Canon CAPT (Canon Advanced Printing Technology)
protocol which makes those devices so called "GDI printers",
see also bug #602944.
We (i.e. openSUSE/Novell) neither provide a driver for
such kind of devices (GDI printers), nor can we provide
any kind of support for such devices, see
http://en.opensuse.org/SDB:GDI_Printers
Therefore the issue does not belong to us
(i.e. the bug report is invalid for us).
In the end all you can do is to use the proprietary driver
from Canon and if it does not work, you can only ask Canon
(or wherever you got a driver for such kind of devices).
We even cannot help you to debug the issue because we do not
have any such kind of devices to reproduce it on our systems.
Nevertheless some hints when you like to debug the issue
on your own, the following might help:
See
http://en.opensuse.org/SDB:CUPS_in_a_Nutshell
--------------------------------------------------------------------
If problems are encountered:
1. Set the "LogLevel debug" in /etc/cups/cupsd.conf.
2. Stop cupsd.
3. Move /var/log/cups/error_log* to another location (or delete it)
in order to avoid having to search through gigantic log files.
4. Start cupsd.
5. Retry the action leading to the problem.
6. Now /var/log/cups/error_log contains many messages
that are useful for troubleshooting.
--------------------------------------------------------------------
When the device is sometimes detected and sometimes not
it indicates a more low-level USB-related issue which
likely depends on your particular device.
As root call "lsusb" to get the USB devices listed
which are currently recognized by the USB-system.
If a USB device is not shown by "lsusb", the device
is unknown by the USB system and nothing can access it
(in particular the printing system cannot access it).
In this case it might help to search for USB-related
(error)-messages in /var/log/messages e.g. using as root
grep -i 'usb' /var/log/messages | tail -n40
to view the last 40 of such messages.
