More printing troubles :(

[-chaos-]

Ive been having more printing troubles in RH 7.2. I added the directories containing rlpr to my PATH, and now when I try to print I get a differnt error message (in Kword or Konquorer, same thing). I even tried reinstalling rlpr, doesn't help. I tried adding the directories contining anything with "rlpr", and adding all the path's of the files containing "rlpr". This didn't help, but as I said I do get a different error message. Heres a screen cap of my new error.

Once I add somethign to my PATH with the "export PATH=$PATH:/path/to/something" how do i remove it from my PATH?

Here are the screenshots of the older error messages, before I added anything to my PATH. http://www.members.shaw.ca/confined/print.png http://www.members.shaw.ca/confined/print1.png
