Hello, i have a 2012 13" cMBP and it connects fine to my brother wireless printer. i have recently purchased another cMBP but it is a 15". On the new one, my wireless printer is not appearing on the list when i click "add" on the print and scan section of the system preferences. There are currently 2 other macs that connect fine to the printer and appear as normal as well as a windows machine and it works fine when people come over and connect from there computers. The printer works fine and appears as normal when i plug into it directly via usb. To me it seems as if there is a wireless feature turned off on my machine but im not positive. hopefully this is a simple fix for some of you and you can help me out! Thanks in advance!
