sane
This is the machine behind scanning on ubuntu.
Install the ppa
sudo add-apt-repository ppa:sane-project/sane-git
If you have the old one you need to
sudo ppa-purge ppa:rolfbensch/sane-git
Then update and upgrade.
gscan2pdf
Brilliant program
Scanning over the network
This can be very tricky.
At the bottom of the /etc/sane.d/saned.conf you need to add:
192.168.2.0/24 (change base on your network but the last 0/24 is same)
Somewhere in December 2020 this broke.
On the machine serving the printers you need to purge ippusbxd
Now we need to install the debs for airscan and ipp-usb
Reboot.
