Problem installing HP Photosmart C4680 on Ubuntu 12.04
Hi!
I've faced a problem trying to install a printer on Ubuntu 12.04. I have a HP Photosmart C4680 and couldn't make it work on Ubuntu 12.04. Before I had Ubuntu 10.04 and the printer was installed using the hplip device driver together with the HPLIP ToolBox. It did work fine until some weeks ago it stopped functioning. At this time I was still using Ubuntu 10.04 and thought that the problem was related to the fact the there would be no more updates for 10.04. So I decided installing 12.04 and thought there'd be no problem installing the printer because this version already comes with the hplip driver. I've also tried using CUPS but didn't succeed. The system doesn't seem to identify that the printer is connected. Is there anything else I could try? Thanks in advance. darthpinguim |
First thing would be to check that the printer be recognized as such.
Please open a terminal, unplug the printer if it was plugged in, plug it in again, wait 30 seconds, then type "sudo dmesg|tail" and copy/paste the results here. |
Here's the result:
Code:
[ 144.788721] type=1400 audit(1338143308.735:31): apparmor="DENIED" operation="file_lock" parent=1 profile="/usr/sbin/cupsd" name="/run/utmp" pid=873 comm="cupsd" requested_mask="k" denied_mask="k" fsuid=0 ouid=0 Best regards darthpinguim |
It seems that you printer be not seen at all by the USB sub-system. Are you sure it is switched on and/or the electrical outlet is plugged in ?
Try this : Make sure you printer is not plugged in Open a terminal Become root (sudo su) type "tail -f /var/log/messages" Plug in the printer Check if you see new output in the terminal and post it here. |
I tried it but it didn't work.
It showed the following message: Quote:

You should type :
Code:
tail -f /var/log/messages |
Actually I did write the slash before var/...
I wrote exactly the way you mentioned. The same message appeared again. |
Strange... Please you post the output of
Code:
ls -l /var/log |
Here's the output of ls -l /var/log

OK, the file seems to be named /var/log/dmesg instead of /var/log/messages in you system.
But as the USB events could be logged in /var/log/syslog as well, please open two terminals instead of one and before you plug in your printer, type in one of them : Code:
tail -f /var/log/dmesg Code:
tail -f /var/log/syslog |
Hi there! Thanks for the replies.
It might seem very weird. Still I don't know what happened, but last night the printer was identified by the system. I tried once more to configure it using the HPLIP ToolBox and suddenly the printer was automatically identified. Anyway here's the output of the commands: tail -f /var/log/dmesg Quote:
