I've configured my N15u running Tomato (Shibby's build 108) to work in Wireless Ethernet Bridge mode (its a secondary router) which is connected via LAN to my main PC and USB to my Canon MFC printer.
The router detects the printer alright, and I've been able to print wirelessly from my laptop (connected to the main router) using port 9100 pointed towards the N15u ip address (192.168.1.1).
Strangely, even though I've setup the printer on my PC identically to my laptop, but when I try to print anything it just returns "Error - Printing". The Tomato logs do not state anything about receiving a print job at all.
Before this the router was configured to work as AP mode and I had no problems printing. Could the Wireless Ethernet Bridge setting be causing this?
