Restrictions
If you use a printer over the wireless LAN, the printer may recognize nearby wireless systems, you
should set a network key (WEP, WPA, or W PA2) to the access point to encrypt wireless transmission.
Wireless communication with a product that does n ot comply with the Wi-Fi standard cannot be
guaranteed.
Connecting with too many computers may affect the printer performance, such as printing speed.
