Controlling Data Reception by IP Address
When the printer uses an LPD port or Port9100 port, the printer can deny or accept data
from certain IP addresses. Follow the procedure described below to set this feature using
CentreWare Internet Services.
Before configuring the setting, disable the print ports other than the LPD port or Port9100
port.
Note
• To set this feature on the control panel, refer to "IP Filter" (P. 89).
• This feature can be used only when the printer uses LPD or Port9100.

asterisk (*).

the right frame and reboot the printer.
