Hi

I am using Mepis 8 on my PC and also have a laptop with windows XP installed. I had the laptop connected to the printer (HP Deskjet 930c) on my PC through the Internet Printer Protocol but it suddenly refused to work. I accessed localhost:631 through my broswer on my PC and there was a error message "permision denied on /dev/lp0". Now my printer refuses to work on my PC also.

I have tried deleting the printer and rebooting and reinstalling it but the KDE print manager lets me get right to the final stage before informing me it cannot create the printer

Has anyone got any ideas? I must have done something to cause this but what! I don't remember doing anything. All I was trying to find the URL to install on my laptop

What are the permissions of it? Show the output of the following if you can:

Corp 769

The answer to ls-al/dev/lp0 is No such File or Directory.
There is in fact an lp0 character device(socket!!) in /dev. Is this possibly because at the moment there is no printer installed

I have tried again to install the printer via KDE and I got the message "unable to create device. Error message from printer manager"

Below is the output from the errorlog

I [24/Mar/2011:08:07:28 +0000] Resuming new connection processing...

Thanks for your interest anyway

So then which one is it? If it is there like you said, my command would give you a result. Try it with appending an asterisk at the end.

Corp 769

Sorry I was running it without the proper spaces the reply I received is 1 root lp 6, 0 2011-03-30 09:14 /dev/lp0


In fact I have now managed to get my printer set up but every time I try to print something I am told the printer is not connected but it is. Incidentally using another distro on a different partition the printer works fine. I feel there is something wrong with Cups although I reinstalled cups from the repositories but it has not solved the problem.


grabro

Can you post the permissions too? I want to verify that the proper owner and groups are correct, along with the permissions just to rule them out. Now besides being that, the messages above from the "errorlog" - Where are you getting them from? /var/log/messsages or dmesg?

CORP 769

The permissions on lp0 and parport0 are owned by root with group as lp. Each can Read & Write. As a user I have access to lp

The permissions on cups.sock are owned by root, Group users Each can Read and Write.

The error log came from /var/log/cups/error.log

Hi

I am still wrestling with my inoperable printer on mepis8.0 although it works fine using mepis8.5. I was in localhost:631 trying to get it working and after running a test page the message "printer not connected" was displayed. Subsequently browsing the error log I cam across the following
"E [03/May/2011:14:35:22 +0100] PID 5894 (/usr/lib/cups/backend/parallel) crashed on signal 9!"

Does anyone know what signal 9 is meant to signify?!!
