[sane-devel] [pixma-backend] Test failed: MG2450

[Rolf Bensch]

Hi Marcus,

Did you follow the installation description in README.linux, which comes
with the source code?

Please test the used Sane version with 'scanimage -V'. You should see:
scanimage (sane-backends) 1.0.25git; backend version 1.0.25

Please install resent Sane from git (1.0.25). I'd like to patch only the
recent version, if needed.

Cheers,
Rolf
