[sane-devel] ESCL

[Mark Dm]

I do not know how it works out for AirSane but with Twain2AirScan I have
tried using different ports for different scanners. I think that AirScane
uses different paths per scanner if I recall correctly.

Having tested multiple port based shares on the same IP address and I had
bad results. Clients like Mopria Android, OSX and other get VERY CONFUSED
and mix up names and icons. It seems that somewhere possibly in the eSCL
2.8 official specsI read that only a single scanner was allowed per IP. I
would get scanner icon A for scanners a and B. part of scanner A Name
would show on Scanner B .

Of course with the way Twain2AirScan shares the scanner a host system can
only share one Windows scanner. The other scanner I used for testing was
the other project on the scannershare.com site , running on a different
port.
