In order to use Brother iPrint&Scan, your Apple mobile device must connect using a
Wi-Fi connection to the same network that the Brother machine is connected. The network can use either
Ad-hoc mode (
Fig.1 - connected directly to the machine without a router/access point) or
Infrastructure mode (
Fig.2/Fig.3 - connected to a network through a router/access point).
Fig.1 (Ad-hoc Mode connection between Brother machine and Mobile device) For an Infrastructure mode network, the Brother machine may be connected using either a
Wireless (Fig.2) network
connection or a
Wired Ethernet (Fig.3) network connection depending on which connections are supported by your Brother machine.
