Lexmark 4580 did not work with OS X Lion 10.7

I am using a Wi-Fi Printer. I have used it with my Windows computer using its wireless feature, and it did print.
My Operating System is OS X Lion 10.7,and my printer is Lexmark 4580.
I cannot print wireless using my Mac.
I checked for the latest updates for Lexmark for Lion and tried downloading it, but it still failed.
I was trying to search the web for online support about this problem, but I could not get specific answers.
Please help me.
