Hi ,

Adding
192.168.1.50    mf8230
to
/etc/hosts
was really effective!


I still have a delay, now around 10 seconds.
As seen below, its not the pixma enumeration that takes all this time (only
one second), so I'm suspecting it's because all the backends are given a
chance to find a device. And given the number of backends this will
obviously take some time.
But then I tried to do
./configure BACKENDS="pixma" --without-snmp --disable-ipv6
and then make
Same result.

To flip things around, I don't mind a full auto-detect taking 10 seconds or
1 minute, if only there was a way to specify the device manually (from
command-line, environment-variable etc)

scanimage -d mfnp://mf8230:8610
does not work,
- can I specify a network device on the command line like this?
- and will that stop the auto-detection?

any help greatly appreciated!
