I am an absolute beginner in Ubuntu. I have installed Ubuntu 12.10 using Wubi from windows 7. It was a clean install.

Now I have upgraded to Windows 8. But the problem I am facing lies with either version of Windows. I work in office where the printer is available through network (probably LAN; I do not know these technical terms). I installed the printer via add printer dialogue box and it was a clean install too. I could print smoothly from Ubuntu.

After few day I changed my username and password from Windows 8 to access the printer.

  1. Now I cant access my printer via Ubuntu despite providing new username and password.
  2. When I add the printer, apparently it is added but when I print the test page I get the message Idle - Tree connect failed (NT_STATUS_ACCESS_DENIED).

Can anyone help me in this regard?

Now I have upgraded to Ubuntu 13.04 but problem persists. someone told me to ping the network from terminal. I did it and it keeps on pinging the whole day.

I do not know what the ping is but whatever it is it must end up after some time as it does when I ping from Windows command prompt.
