iMac OSX 10.9.5 Shows Brother MFC 8710DW Printer Is "Offline" and "Not Connected T
I have a Brother MFC 8710 DW that I've had for the past 4 months. It works perfectly fine with my other devices (iPad, iPhone, Windows PC and Macbook Pro) but it doesn't work with my iMac OSX 10.9.5. I did the things listed below but it keeps on telling me that the printer is not connected to my computer and whenever I check its status, it keeps on saying "offline." I've tried to contact Apple and they said that it's Brother's problem and that I should speak with them. However, when I called Brother, they said that it's Apple's problem. I'm at lost on what I need to do. As much as I love my iMac, I am tempted to return it back. Please help.
Things I've done so far but did not fix the problem:
1. Unplugged the printer, iMac and router and plugged it back in after a few minutes.
2. Removed the printer from my iMac and added it back.
3. Reinstalled the software from Brother.
4. Repaired the disk.
5. Plugged the printer and router directly to the wall.
6. Turned off and restarted my iMac and printer.
7. Downloaded the most recent OSX software.
iMac, OS X Mavericks (10.9)
