[arch-dev-public] help wanted / IPP based printing/scanning

[Andreas Radke]

There's some major effort going on to move from driver based scanning
and printing to driverless scanning and printing both based on IPP
specifications offered by newer devices.

While IPP based printing is already there for some time and usable with
cups+cups-filters [1] there's more work going on recently for IPP based
scanning lately. There are a few projects we should probably support
and add to our repos. I'm thinking about adding Sane-airscan [2][3] to
extra.
There's also a new ipp-usb proxy to allow IPP protocol access with USB
connected printers and scanner as well [4][5]. I've prepared a simple
package here of this one.

Sadly my own printer is has a broken IPP implementation and thus can't
be used with driverless printing [6]. My scanner is an old extra
devices with plain usb connection. Both devices keep working well and I
have no plan to replace them. So I cannot test anything of the new IPP
stuff.

If there's desire to have the new IPP stack fully available form our
repos I can do the packaging because it's heavily related to
recent multidevices and openprinting.org projects. But any help is
welcome and I would prefer someone to become a backup and co-maintainer.

If somebody has interest to help out here and maybe owns a modern IPP
based multidevice please drop me a line.

If nobody steps up or complains I plan to add sane-airscan and ipp-usb
and maybe more if needed.
