Once you have it all up and running and working.
Buy a Pi ZeroW
Get a card just the size needed and image what you have across.
Then run you scanner/printer from there.
You then have the Pi3 back for my fun and play.
The reason to use Raspbian over Noobs to Raspbian, is initial headless mode is that little bit easier. Though as you're doing it from a mouse/keyboard it shouldn't be a problem.
If you go into Raspberry Desktop setting (in the menu or via terminal, with sudo raspi-config
) you can enable both SSH (for remote text logging in) and VNC (for remote Desktop logging).
Then use whichever you are comfortable with for file transfer etc. (you can even do it from Android devices too, some apps will give you a normal icon file view).
Either in your router, find the setting to reserve an IP address for the Pi's mac address, so you always know the IP address, or scan for it (Fing is such a program) or some other way somebody will point out.
HELP is here, mainly the bottom parts
especially the Remote Access parts.
