Public bug reported:
In Focal we are still a bit old-fashioned regarding scanning. We are
still at the ancient SANE 1.0.27! That is really INSANE.
Current version is 1.0.29 and it contains a very important new feature
which will make hundreds (thousands?) of new scanners work with Ubuntu.
This new feature is Apple AirScan support as a client. I have introduced
a lot of nice printing stuff to support AirPrint, making lots of
printers (practically all modern network printers) working, and all the
multi-function devices under these (printer and scanner in one) do
AirScan, so all these scanner will work with SANE 1.0.29 (if yours does
not, it is a bug in SANE, please report).
The AirScan support is provided by the new "escl" backend. supporting
the eSCL protocol AirPrint is based on. The protocol uses HTTP and XML,
so this works out-of-the-box if your printer is connected to the
network, if it is connected via USB it work via IPP-over-USB using the
ippusbxd package.
Changes list from upstream:
- Backends
+ adds an escl backend (theoretically supporting all AirPrint devices with a
scan unit
+ adds support for 23 new scanner models via existing backends
+ significantly changes genesys and pixma backends
+ fixes bugs in canon_dr, fujitsu, hp3900, mustek_usb2, plustek and
xerox_mfp backends
+ fixes all compiler warnings on Debian 10 (#120)
+ fixes portability issues for uClibc-ng and MacOS builds
+ adds support to record and replay USB I/O traffic
+ adds timestamps to debug logs
