Driverless scanning for WSD and ESCL supported scanners is coming

[Zdenek Dohnal]

Hi all,

I would like to announce sane-airscan project [1] will be shipped in the
official Fedora repositories from Fedora 32 [2].

sane-airscan implements a backend for Microsoft WSD and ESCL (usually
called AirScan, originating from Apple) protocols, which are common in
newer (2012+) scanners and multi-function devices for scanning.

Using sane-airscan, newer devices don't need vendor proprietary software
for scanning any longer (e.g. hplip with its hp-plugin).

The project is divided into main package - sane-airscan - which contains
helper tool - airscan-discover - for discovering devices in setups,
where automatic DNS-SD discovery doesn't do the trick, and subpackage -
libsane-airscan - which the main package requires and the common known
project for scanning - sane-backends - will require to get the backend
into common scanning stack installation.

Please feel free to test it.


Have a nice day,

Zdenek

This is great news, thanks to you and Alexander Pevzner for making it
happen. It makes me smile even if my current printer is not supported
and still requires hp-plugin.

Hi Dominik,

if your device is capable of AirPrint (is network printer+has enabled
IPP+capable to be installed as '-m everywhere' model via lpadmin), there
is a good chance (unless you are unlucky like me with Laserjet m1536dnf
- supports AirPrint, but not AirScan) that it supports AirScan too.

 Will it be possible to use a Fedora machine as a server, so that I can
have an old scanner connected to it via USB and then shared with other
devices on the local network via those protocols?
That would be neat.

If your clients are SANE supported OSs, you can already do that with 
saned. For example this documentation

https://wiki.debian.org/SaneOverNetwork

Hi Jirka,

IIRC it is possible even now via saned on the server, but saned doesn't
use WSD or ESCL, just simple TCP transfer between client and server.

In practice it looks like - you have a proprietary or sane-backends
supported USB scanner (sane-airscan doesn't work for USB devices), you
set up ACL on saned and setup clients to connect to the server.

sane-airscan is a backend for communication with scanner supporting
WSD/ESCL, it doesn't use those protocols for sharing the device.

 From the README, it looks like some manufacturers allow eSCL to work 
over USB too:

   However, most (all?) of the eSCL devices will also work over USB, if
   IPP-over-USB daemon is installed on your computer

and some are even USB only:

   [2]: this device is USB-only, but it works well with the IPP-over-USB
   daemon.

I hope this becomes a trend for non networked scanners too.

I had a suspicion ipp-over-usb daemon like ipp-usb or ippusbxd could
help, but I wasn't sure (it was created for supporting USB printer
devices), so didn't want to spread any mystification.

ipp-over-usb daemons - ipp-usb and ippusbxd - are on my list what to
package, they will come into Fedora this year (I hope).
