Older ScanSnap scanners don't have Wifi, only USB. The one I have (S1300) is not supported by the manufacturer anymore. The software still works on my Intel Mac, but it won't get any more fixes from this year on. It might still work on Apple Silicon with Rosetta, but I haven't tried that yes.

I looked into connecting the scanner to a Raspberry Pi in the past, but just could not make it work unfortunately.

I'm not sure how I would do that on my model (ScanSnap S1300i), it connects over USB and has no touchscreen/control interface or network port, or wifi capability, you have to connect it to a computer via USB.

This works fine on say, a Mac, with the official Fujitsu ScanSnap software, and I'm guessing _that_ supports saving to a samba share, but I wanted a solution that's

1. completely headless, i.e. no desktop machine required and experience needs to be friction free as the headless part means the only way to interact with the scanning function is to press 1 button

2. linux compatible, as I wanted to connect it to a Pi. I had to dig for the drivers, Fujitsu didn't have the right ones for my model on their website!

I couldn't find any official software from Fujitsu, but I found the drivers eventually, so ended up coming up with connecting the scanner to the Pi over USB and glueing the bits together to drop the PDFs onto the samba share

The button is located on the scanner, and I run "scanbd" [1] to listen for the button press, this is what coordinates the scan function (feeding the paper through) and then post-scan -> running a script to collate + create PDFs

I have a SnapScan N1800 which makes a big difference and eliminates these complications.
