PRO-200 will not connect via wifi

[AVCH]

I am attempting to connect my PRO-200 to my iMac via wifi. Both are connected to the same wifi address but when I try to print I am told that the printer is offline, despite both claiming to be connected.

If the material here on wi-fi support doesn't help give Canon a call at 1-800-OK-CANON.
