My computer has two network interfaces, eth0 (wired) and wlan0 (wireless), to connect to my router. The wired connection goes via a small network switch to which a laser printer is also connected.
The computer normally uses the wired connection but sometimes I need to disconnect that and use the wireless so that I have a wireless connection to the router but the cable is disconnected from the router leaving my computer connected to the switch which also has a laser printer connected to it.
Is there any way that I can use the laser printer via eth0 when my computer is running on wireless?
