I have an issue with my printer Brother DCP9020-CDW connected on WIFI to my XR500 (FW v2.3.2.108)
I can see it in the devices on my router administration, I can scan document from my printer and send it directly to my Google Drive (so, I know that the wireless link is OK), I can start a scan from the brother software on my computer (so, I know that my computer see the device), but I can't print !
Documents goes to the print queue, but after few second, an error occurs.
It's like the queue was not transfer to the printer.
I didn't encounter this issue with my Livebox before (I replace it with the XR500).
Is there an specific parameter to allow my computer to communicate with printer througth the router?
This is an odd one, as you said, there is obviously a wireless link there so why isn't it printing. Could you try disabling QoS fully? You could also try toggling SIP ALG/IGMP Proxying in WAN Settings please.
