Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

Apparently, there's a permissions-related problem in the hplip 2.7.9-1 package. As a non-root user, you'll get a "Unable to communicate with device" error when trying to access the printer via hp-toolbox. Consequently, as a non-root user, you can't also print (since you can't access the printer hardware).

Can anybody else confirm this?

Weird. What's the output of:
$ groups
?

BTW, did you do anything after the upgrade?

I didn't anything. I just checked the printer for your post.

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

I just had the same problem after updating. I got it solved by restarting. As a restart is normally not the only solution (otherwise we would be running windows ) I guess there is some other way .... I suspect it has to do with udev, but I didn't want to try around how to "reset" udev on a running system, but I guess that's much easier than I currently think.

I was able to solve the problem too. At long last!
What the hell is the connection of the 'camera' group to the printer?
I was able to access the printer hardware after adding my user to the camera group.

On the other hand, I still can't print anything. I can already access the printer from hp-toolbox but I can't print!

I had a different message regarding foomatic. But I did:

sudo pacman -S hplip -f

Does you printer have a builtin card-reader ??

Mine as one, and I also can't print (but see the printer in cups or hp-toolbox), and my printer is also in the camera group.

The problem had also been discussed on the mailing-list [http://archlinux.org/pipermail/arch/200 … 15388.html]

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

the printer is often mounted into /dev as root:camera. So be sure your user is both in camera and lp groups (you need to relogin to have the new groups applied).

Also, remember to remove "hplip" from the daemons in rc.conf as it is no longer needed.

A good way to find errors is with hp-check (as normal user).

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

Something wrong ??

everything seems okay. What I'd do is:
- turn off printer
- remove the HP printer from cups
- remove hplip from daemons in rc.conf
- reboot
- turn on printer
- reinstall the printer

Edit:

also try

sudo chown root:lp /dev/bus/usb/00X/00Y

where X and Y are the USB numbers where your printer is connected to.

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

I was able to solve the problem too. At long last!
What the hell is the connection of the 'camera' group to the printer?
I was able to access the printer hardware after adding my user to the camera group.

On the other hand, I still can't print anything. I can already access the printer from hp-toolbox but I can't print!

Does you printer have a builtin card-reader ??

Mine as one, and I also can't print (but see the printer in cups or hp-toolbox), and my printer is also in the camera group.

Nope. My printer doesn't have one. It's an HP Deskjet 3845.

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

the printer is often mounted into /dev as root:camera. So be sure your user is both in camera and lp groups (you need to relogin to have the new groups applied).

Also, remember to remove "hplip" from the daemons in rc.conf as it is no longer needed.

A good way to find errors is with hp-check (as normal user).

Actually, $ ls -l /dev/bus/usb/*/*:

crw-rw-r-- 1 root camera 189,   0 2007-10-08 05:43 /dev/bus/usb/001/001
crw-rw-r-- 1 root camera 189, 128 2007-10-08 05:43 /dev/bus/usb/002/001
crw-rw-r-- 1 root camera 189, 256 2007-10-08 05:43 /dev/bus/usb/003/001
crw-rw-r-- 1 root camera 189, 384 2007-10-08 05:43 /dev/bus/usb/004/001
crw-rw-r-- 1 root camera 189, 385 2007-10-07 21:46 /dev/bus/usb/004/002
crw-rw-r-- 1 root camera 189, 512 2007-10-08 05:43 /dev/bus/usb/005/001

All of my USB devices are owned by root:camera. Why is that?

BTW, I did the steps that you've specified but I still can't print.

I answer to my own question.

By moving /etc/udev/rules.d/gphoto.rules to /etc/udev/rules.d/54-gphoto.rules so that the hplip rules (/etc/udev/rules.d/55-hpmud.rules) apply after, the printer have the good rights after a reboot.

Thank you to solsTiCe for the tip

Everything is working fine after the permissions got fixed. So it was indeed a permissions-related problem...

Yes, probably it's that. I've, too, used the sudo command and everything is working now .

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

I can get my HP3030 printer to work only if I select the nonHPLIP printer from the KDE list of printers. If I choose the HPLIP version of the printer, it won't print.

Later ... This worked for me:

By moving /etc/udev/rules.d/gphoto.rules to /etc/udev/rules.d/54-gphoto.rules so that the hplip rules (/etc/udev/rules.d/55-hpmud.rules) apply after, the printer have the good rights after a reboot.

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

Not sure which of the suggestions worked..but one of them worked, (at least after the 3rd trial and reboot) because I tried them all.
Thanks to all.

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

I have the same problem but my printer is a C3100 series with scanner.. so udev give the wrong permissions.

hp-check ..

Checking for permissions of USB attached printers...
HP Device 0x5611 at 001:004:
    Device URI: hp:/usb/Photosmart_C3100_series?serial=MY69SC613F04P9
    Device node: /dev/bus/usb/001/004
    Mode: 0664
getfacl: Removing leading '/' from absolute path names
# file: dev/bus/usb/001/004
# owner: root
# group: scanner
user::rw-
group::rw-
other::r--

if I change the permissions to lp then all printing functions work ok but not scanner.

have any ideas how to solve this problem ?

thanks

Re: Permissions problem in hplip 2.7.9-1 [FIXED: FS#8240]

I have the same problem but my printer is a C3100 series with scanner.. so udev give the wrong permissions.

hp-check ..

Checking for permissions of USB attached printers...
HP Device 0x5611 at 001:004:
    Device URI: hp:/usb/Photosmart_C3100_series?serial=MY69SC613F04P9
    Device node: /dev/bus/usb/001/004
    Mode: 0664
getfacl: Removing leading '/' from absolute path names
# file: dev/bus/usb/001/004
# owner: root
# group: scanner
user::rw-
group::rw-
other::r--

if I change the permissions to lp then all printing functions work ok but not scanner.

have any ideas how to solve this problem ?

thanks

Have you upgraded already to libgphoto2 2.3.1-3?
