HP PSC 750 Printer Regression: unable to connect hpssd socket 2207: Connection refused.

[nglnx]

My HP PSC 750 (usb) printer, which worked in all previous versions of Ubuntu, has the following problem in Ubuntu 8.04:

It is detected when plugged in, as can be confirmed by the visual cues in the pannel, by going to System/Admin/Printers and by checking syslog.

However, it does not print anything.

Syslog gives the followinf info:

As to the detection:

I consider this to be a serious regression.

[nglnx (nglnx)]

It still happens with the release version of Ubuntu Hardy.

[nglnx (nglnx)]

It seems that disabling apparmor removes the message:

kernel: [ 194.693603] audit(1208351567.253:3): type=1503 operation="inode_permission" requested_mask="::rw" denied_mask="::rw" name="/dev/tty" pid=6807 profile="/usr/sbin/cupsd" namespace="default"

And printing resumes.

I can confirm problems with HP OfficeJet J3680. Logs look very nasty:

May 5 20:38:33 titanium Officejet_J3600_series?serial=CN7CO5Z5K8053D: prnt/backend/hp.c 496: unable to connect hpssd socket 2207: Connection refused
May 5 20:38:33 titanium kernel: [ 111.212528] usblp0: removed

This is with apparmor disabled. I don't get any output on printer. hpssd.py isn't started, but with it started there's no change in behavior.

[PabloRQ (pablo-romeroquinteros)]

Only happens when trying to print from a windows xp to ubuntu 8.04 with samba sharing a HP F4180.
The printer works excellent when printing in local (ubuntu).
With this bug, it doesn't print anything from samba.

[jan (jan-ubuntu-h-i-s)]

Probably related problem:
Most of the times, my machine (after upgrade to Ubuntu 8.04) does NOT recongize my local printer, connected through USB.
 Photosmart_C4100_series?serial=MY759J12M204J7: prnt/backend/hp.c 496: unable to connect hpssd socket 2207: Connection refused
Also, just after a print job, the printer disappears. At that moment even "sudo lsusb" does not show the printer anymore.
Another nasty regression bug in Ubuntu 8.04, making this the worst release I've seen.

[Ante Karamatić (ivoks)]

jan changing PPD solved this issue for me, i suggest tring that.

[Forest (fdenger-gmail)]

This bug shows the same errors I am getting about hpssd socket connection refused. Also the denied_mask="::rw" section as well, and usblp0 removed. Though printing locally still works after the "usblp0 removed" portion is displayed sometimes.

Sometimes I can print from a remote system, and sometimes I can't. What does happen is that my printer is completely locked up once a print fails, and I have to unplug power to printer, unplug usb, replug power, power up, then replug usb, in that order specifically, to make it not lock up again, then sometimes the first print from a remote system will lock it, sometimes not. And sometimes, after a reboot of the printer that way, it will go ahead and print the remote print job from the queue, the very one that crashed it in the first place. I am not printing from samba remotely, but via http cups server.

disabling app-armor did not product any definitive results, still getting lockups 99% of the time.

I believe this bug to be closely related to https://bugs.launchpad.net/ubuntu/+bug/241781

Many people are hinting at a permissions problem, but I have no idea how to fix something like that.

[jan (jan-ubuntu-h-i-s)]

Ante: Can you elaborate on what to change ?
Do you have a link to another bug# of answer that describes what you did , or list the commands you used ?

[rickyrockrat (rickyrockrat)]

I had to add these to the /etc/apparmor.d/usr.sbin.cupsd file:
#Samba access
  /var/lib/samba/passdb.tdb krw,
  /var/lib/samba/secrets.tdb krw,
  /usr/share/samba/panic-action kUx,
  /var/lib/samba/account_policy.tdb rw,

And that fixed the permissions issues I was having in the logs, however I still get this sequence in the logs.

This bug has been around since 2/2007. It is now 2009, and rather embarrassing for the Ubuntu community that it still exists. Does anybody know how to fix it besides upgrade? Intrepid gives me random boots and hard locks related to X, so I don't want to go there.

[Jamie Strandboge (jdstrand)]

The bug should be filed against cups, since it ships the profile.

[Till Kamppeter (till-kamppeter)]

Pitti, can you look into the issues of AppArmor interfering with Samba and HPLIP here?

[Don Pittman (donpittman)]

I have had the same problem for over a year with Fedora and now Ubuntu. I am currently running Ubuntu 10.04 with hplip 3.10.2-2ubuntu2.1 and cups 1.4.3-1ubuntu1.3. Is there a plan to fix this bug?

[Thomas Hotz (thotz-deactivatedaccount)]

Till, is there a plan to fix this bug? Don have you still this printer and this problem? Thank you!
