system-config-printer and hal_lpadmin recommend different driver

hal-cups-utils did not read the device IDs of the printers correctly. I have fixed this now.

Please replace your file

/usr/lib/hal/scripts/hal_lpadmin

by the attached file and make it executable with

sudo chmod 755 /usr/lib/hal/scripts/hal_lpadmin

Then unplug and replug your printer. Does it get re-enabled now?

This bug was fixed in the package hal-cups-utils - 0.6.19+git20090217-0ubuntu3

    Fixed reading of the printer device ID (LP: #306301) and let hal_lpadmin
    use the same method for finding already configured CUPS queues on plugging
    and unplugging the printer (LP: #341646, LP: #139317).

I'm the reporter of bug #298701 which has been marked as a duplicate of this one.
In Jaunty with all the available updates (and in particular with hal-cups-utils 0.6.19+git20090217-0ubuntu3 installed), the auto-configured driver for my HP Deskjet 895Cxi is HP DeskJet 895C Foomatic/pcl3.
This is not correct : The good driver for this printer is the HPIJS one.
If you need more information, do not hesitate to ask.

Anyone who gets different default driver selections by Plug'n'Print and by system-config-printer, please do the following:

1. Remove all print queues for your printer, then unplug and plug your printer again. As soon as the printer with the magnifier in the system tray disappears (and a notification bubble about a new printer appears) attach your /var/log/syslog file to this bug report. Do not compress the file.

2. Start system-config-printer by entering "system-config-printer" in a terminal window. Click the "New" button, select your printer from the auto-detected local printers and click "Forward". If you are not on the last screen of the wizard now (entering of queue name, "Apply" button), click "Forward" until you reach that screen. Click "Cancel" and copy-and-paste all text which was written into your terminal window after the "system-config-printer" call into this bug report.

3. Configure your print queue again to use the driver which you use for your daily printing (with system-config-printer).

My printer : HP Deskjet 895Cxi.
Here is the information you asked:
1/ syslog output attached
Driver selected: DeskJet 895C Foomatic/pcl3

2/ output of "system-config-printer --debug" (without --debug there is no output):

If you need anything else, do not hesitate to ask.
Thanks for your help.

Can you update system-config-printer to the current state of Jaunty and try again? HPLIP 3.9.2 introduced several problems with model names which are worked around in the newest system-config-printer.

Hi Till,

Thanks for all your work.

Here is the result with all available updates:
1/ syslog output attached
Driver selected: DeskJet 895C Foomatic/pcl3
No improvement.

2/ output of "system-config-printer --debug" (without --debug there is no output):

Fixed upstream in system-config-printer 1.1.x, commit f28fe3e. Affects binary package python-cupshelpers.

Pascal, Fred, please replace the file

/usr/share/python-support/python-cupshelpers/cupshelpers/ppds.py

on your system by the attached file and try again. Now you should get the same default driver choice.

Till,

It is fixed indeed !
Driver selections by Plug'n'Print and by system-config-printer now gives the correct driver and printer model !
Thanks a lot !

This bug was fixed in the package system-config-printer - 1.1.3+git20090218-0ubuntu14

system-config-printer (1.1.3+git20090218-0ubuntu14) jaunty; urgency=low

  * debian/patches/50_work-around-broken-device-ids-in-hplip-ppds-match-model-case-insensitive.patch:
    The device IDs in the PPDs of HPLIP 3.9.2 are completely broken and it
    happens also that some printers report an all-uppercase device ID. Made
    system-config-printer find the correct PPD/driver also in these cases.
    Upstream fix (LP: #298701, LP: #306301).

  * debian/patches/53_plugin-autoinstall-with-hplip-3.9.2.patch: Upstream
    fix to update check whether proprietary HPLIP plugin is already installed
    so that it also works with HPLIP 3.9.2 (LP: #347839, LP: #289410).
