Hi. I will try to help. But I am missing something. Your printer "has been working fine." Then you say you've "tried everything to connect the printer." This makes it sound like it HASN'T been working. Could you be kind enough to clarify? Thanks!
Have you made any changes to the networking settings EVEN THE LEAST?
O.K. I really can't say at this point in the absence of more detailed diagnostic information. I'm going to step back and let another Mac enthusiast take a look. Good luck!

This isnt a network issue.. It could be one of several issues. The easiest and most effective way in which I can help you fix this issue is via a screen sharing session. If I am unsuccessful, you will be entitled to a full refund of all fees.
As you requested, I am including the refund link below. You are welcome to seek help eslewhere and comparison shop.
No other reputable company will offer you a a fix it or refund guarantee. So if you change your mind and decide you want help fixing the issue, let me know. I can say that this isnt a simple printer fix like turning the machine off and on or pressing a few buttons. After all, if it was a SIMPLE fix as you mentioned then Apple support would have fixed it for you already, wouldnt they?
