HPLIP

How to set permissions of printer dev in Ubuntu Jaunty using HP backend

Asked by digger vermont

Hello,

I'm working with a Dell 1425N laptop and a Photosmart D7560. Ubuntu Jaunty is installed. HPLIP is 2.8.12 and the kernel is 2.6.28.

Similar to other questions the problem with permissions. But no answer for me. I'd love to get it figured out so I can write up a yicket for it. Here goes...

~$ lsusb
Bus 007 Device 005: ID 03f0:6f11 Hewlett-Packard

~$ ls -l /dev/bus/usb/007
total 0
crw-rw-r-- 1 root root 189, 768 2009-01-15 17:03 001
crw-rw-r--+ 1 root root 189, 772 2009-01-15 18:14 005

That makes sense to me since the printer also has a storage device. The system also sets up lp0 and a scsi device for the storage. I noticed that the plus-sign gives it an acl attribute.

~$ ls -l /dev/usb
total 0
crw-rw---- 1 root lp 180, 0 2009-01-15 18:14 lp0

So there is also a printer device set to the group lp.

I can't print with the hp backend that uses /dev/bus/usb/xxx/yyy. I can print if I chmod the dev to 666. I can also print with the usb backend that I guess uses /dev/usb/lp0.

So where does the probelm lie? With cups, hplip, hal, policykit. Do acls need to be set somewhere?

Below is the from dmesg and then hp-check.

Thanks for you help - digger

We haven't started testing on jaunty yet--however it appears there is a problem. I'm going to do some testing on the lasted build tomorrow and I'll send some more information after.

Are you using the daily snapshot?

Thanks.

Yes, I update it regularly. I just tested jaunty-alpha2 on a usb-flash-drive. I can print with the hp-backend from there.

The difference I saw was that /dev/bus/usb/xxx/yyy was owner=lp group=scanner. It was set by /etc/udev/rules.d/024_hpmud.rules. That file or similar doesn't exist in the current jaunty.

This stuff below is from Jaunty-alpha2

Digger,

This should be fixed with the latest Jaunty updates.

You can also see this thread:

https://bugs.launchpad.net/ubuntu/+source/hal/+bug/318262

I have confirmed that the update is working okay for me.

Thanks for your support of HPLIP.
