I use RHEL 6 in a VM VirtualBox, Host system is Windows7. I am trying to configure printer, I used
I am getting an error prompt saying
Pls help me fix this
Screen Shot

Thanks in Advance

Spell out your words. And have you tried running "system-config-printer" from a terminal window, as root, rather than typing it in the "Run Command" box? Also, have you checked RedHat's knowledgebase or called RedHat support?? You are paying for RHEL, so you have access to those resources. If you're not paying, then you SHOULD NOT be using it.

@TBOne: Thanks for your interest in helping me.
I have tried as root too. Still the same error Here is the Screen Shot

Additional Info: I do not have access to those resources because I am using a evaluation version provided to me by my university.

Nope, that is a different error than the one you posted originally. All that means is that the command is not found...as in, the command isn't in your path. So, type in "locate system-config-printer", or "find / -name system-config-printer", and use the whole path name to the command to execute it.
Then your university has access to them under their support contract. Ask your professor

lets see
the first "error"

"home/user_1/system-config-printer" -- no such file or directory

you did NOT run a command for the printer
you tried OPINING a file that did NOT exist

just HOW did you get that ?????
as in what did you do ?


the second one
you used "su" and NOT the NEEDED way to become root from a normal user
" su -" with a dash
there is a VERY big difference in the two

also why not use the web interface for cups
http://localhost:631/
that above link is YOUR computer

but this is a VM install on a windows box so ???????
did you configure VB to allow the printer?
and if this is a wireless printer like most new ones are
you CAN NOT use it in a vm

also RHEL6 is not free so you DID pay the standard one year support contract
$ 299/year
so you have access to the red hat knowledge base
https://access.redhat.com/knowledge/search
( you will need to login to red hat )

if you are NOT going to pay for rhel then DO NOT use it
install one of the free rebuilds
CentOS 6.2
ScientificLinux6.2

thanks TB0ne and John VV. A simple restart fixed the issue. I know it`s so stupid of me not to try that in the first place. Also the web interface was nice
