Right. But here, the pi is having multiple roles. It is a print server, it
has an HDMI screen used as PoS (payment handling and some display stuff).
The role of a router was added to it later.

I have a dongle that provides ISP connection over USB as well as wifi.
Here I am using it as a usb modem to pi and pi shares the connection with
other devices. This dongle could have served as a router as well. But pi
based router gives me a more self contained setup with flexible choice of
internet connectivity device. And even if the device is taken away for a
while (which sometimes happens) at least my intranet setup works fine.
