I'm having problems with getting my Samsung SCX-4500 printer to communicate with my Macbook (OSX, 10.4). I get a message saying that it could be either a bad connection or that I may need to change the printer settings. What fixes the problem temporarily is when I "repair permissions" under disk utility. However, if I restart the computer or don't print for a while, I have to repair the permissions again in order to make it work. Any idea on how to permanently fix the problem?? Thanks!
