Good news they found the problem and the cause.
I have always been curious best to how are Canon and Brother Wireless inkjet printers/scanners work as well as they do when Wi-Fi on our Networked iMacs there's normally turned off.
I think the Canon is using an ethernet connection and the brother is using the Wireless connection from the wireless router where I believe it is registered for our use.
Anyway it works very well from our IMAcs and other iDevices the printing is exceptionally fast especially the Brother inkjet. Here's hoping I haven't spoken to soon...
