I am able to ressolve this problem by installing CUPS Version 1.5.
Now the problem is that I am able to print Self Test Page via console.
But, If I print Test Page or any other files, it will return completed, but my printer has no response. Since CUPS returned completed, there is no logs which can be traced.

Do you have any clues for this problem?

Thanks a lot for your help.
