Hi,

In order to gather more information about your Ubuntu printer configuration, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy/paste each command into the Terminal and then hit <enter>)

lsmod | grep lp
lsmod | grep ppdev
dmesg | grep par
lpinfo -v

Step 3: Please post results (copy/paste terminal output from each command) on this thread

Regards,

Mark

Thanks I did the abovementioned comnmands an this is the result:

jurgen@tux:~$ lsmod | grep lp

Hi,

Open a Terminal and enter the following command:

sudo gedit /etc/modules

# Add the following line to the end of the /etc/modules file

ppdev

Afterwards, reboot to enter the BIOS and reset all BIOS values back to default values. Then turn the printer off and on again. Then reboot the pc and retest configuring the printer in Gnome.

Then try playing around with the parallel port settings in the BIOS (if they exist there)

Then turn the printer off and on again. Then reboot the pc and retest configuring the printer in Gnome.

If this does not help, please specify the exact model and make of your printer.

Hope this helps,

Regards,

Mark

Thank you very much but that did not work.
I opend the modules and changed it like that:

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
floppy
ppdev

you were right that the ppdev was missing - I had to write it, but after then it was stable existing in this file (I looked a few times).

I tried playing with the BIOS (I have a Siemens SCENIC 600 computer with so calles PhoenixBIOS which gave you at least 40 possible settings - I have tried the default and a few other which looked well possible without success...

My Printer is a HP-Laser-Jet 6P (old fashioned and worked until ubuntu 9.04 without any problems - I have two computers connectet to one printer (the abovementioned) with a mechanical switch. Also this worked perfectly under Ubuntu 8.04 and 8.10. (And still does under WIN XP on the other computer)

The possible settings for the parallel port in BIOs are like this: you must at first choose the Parralel either to Auto or Enabled , Disabled or OS-Controlled.

If you choose Enabled you got the decisions between ECP, EPP printer and bidirection and then you must at last decide between adresses like this: Enabled>Printer>378h,IRQ7 or 278h,IRQ5 or 3BCh,IRQ7 .... It would be possible to draw a flowchart scan it and poste it if this may help... but you see it is nearly impossible ty find the right thing with trial and error.
The default Setup is: Auto>Bidirection (without such cryptic values like above) (that seems the right for me cause i have never changed anything before (e.g. as I used my printer for the first time. #
In all zhese settings it is possible to print right out of the BIOS with the PRINT-key on the keybord (so the contact is physically well).

If I tried to establish contact via HPLIPS the fault was like this:

Hi,

Please also try all the suggestions in the following bugreport:

https://bugs.launchpad.net/ubuntu/+source/gnome-cups-manager/+bug/29050

If all the suggestions there do not help (like manually running "sudo modprobe ppdev" in a Terminal), then I suggest you create a new bugreport for your issue.

Regards,

Mark

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball
has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode
will check both of the above cases (both compile- and run-time dependencies).
