Unauthorized access to a wireless network can be prevented by using strong encryption methods like WPA2, setting up a strong password, enabling network security features like MAC address filtering, and regularly updating the router's firmware.
Firewall
It uses a 128-bit pre-shared hexadecimal key to prevent unauthorized wireless access.
This is assuming that there is no outside access to the Ethernet network such as a Internet connection. If there were then firewalls would be needed to prevent a outside intrusion of the network. In addition to physical access security, a wireless network requires authentication and encryption to prevent unauthorized devices from connecting to the wireless network or capturing and decoding the data that is being transferred via a wireless network connection. If the wireless network has outside WAN access then you would also need firewalls as with the Ethernet network.

A rogue access point is a wireless access point that is not authorized or controlled by the administrators of the network that it is connected to. Depending on the intended usage, it may or may not use the same SSID as the legitimate access points on the network. Rogue access points are considered a security risk, either because they can allow unauthorized access to the network, or because they may be connected through a sniffer in order to capture network traffic passing through them. Any access point can be considered a rouge access point if connected to the network in an unauthorized manner.
use wireless encryption. for example, WPA or WEP (http://en.wikipedia.org/wiki/Wifi#Network_security)

Unauthorized access is the use of a computer or network without permission. Unauthorized use is the use of a computer or its data for unapproved or possibly illegal activities.
If the printer can connect to the wireless access point via ethernet and that the printer has been enabled to be used on a wireless network then in theory yes.
