Only the title is enough to explain the reality of the problem. My printer is supported(x4690) and it is working fine when it is connected via USB cable but when I try to connect that wirelessly then it started showing me the problem and I am not able to establish the proper connection to my printer and my computer. I have already tried everything that I know to solve the problem.
The only thing that I know about this error is when I try to print any document and run the log for that then it shows me some error message that is given below:
Stopping job because the scheduler could not execute a filter.
E [30/Aug/2009:14:17:13 +0100] Unable to execute /usr/libexec/cups/backend/lexnet3: insecure file permissions (0100755)
Please help if you have any suggestion for this issue. Any helpful suggestion with this problem will be really appreciative.
