Hey! I have a Lexmark Impact S305, a wireless all-in-one printer, but do have some trouble with the wireless functionality with the MacBook Air (w/ OS X Lion). The printer works fine with my PC but unfortunately I don't get any contact with it wirelessly through my MacBook Air. I've installed and updated all the drivers available for the exact model of my printer, from the company's web site. The only way to make it functioning is connecting with the cable which is pretty unnecessary due to the fact that it's a wireless printer. So I wonder if any of you know how to solve the problem? Thanks in advance.
