[Printing-architecture] Mopria has published the eSCL protocol specification

[Till Kamppeter]

Question is now whether we should implement the new architecture of 
Scanner Applications/sandboxable scanner drivers with eSCL or whether we 
should use IPP Scan.

eSCL is probably easier to implement, as we have sane-airscan containing 
all client code and AirSane containing the server code, both needing to 
get updated to fully comply with the public eSCL standard and their code 
being moved into (a) library/ies, so that one can easily integrate it 
with PAPPL. No need to implement a new protocol completely from scratch.

On the other side with IPP Scan we have more consistency as all the rest 
(printing, IPP System Service) is also IPP.

WDYT?
