Restrictions

If you use a printer over the wireless LAN, the printer may recognize nearby wireless systems, you should
set a network key (WEP or WPA/WPA2) to the wireless router to encrypt wireless transmission. Wireless
communication with a product that does not comply with the Wi-Fi standard cannot be guaranteed.
Connecting with too many computers may affect the printer performance, such as printing speed.
