The backend version bit shows whatever sane_init gets back as the version of the backend. In most situations that will be the dll backend but you could set up your system to have scanimage use a specific backend directly. So for the pixma backend that becomes 1.0.17, if I got my maths right. This is compliant with the SANE spec. You're supposed to return the *backend* version in the sane_init() call. The *backend* version is defined in section 4.1: SANE version control also includes a minor version number and a build revision. While control of these numbers remains with the implementor of a backend, the recommended use is as follows. The minor version is incremented with each official release of a backend. The build revision is increased with each build of a backend. So a backend could even return something like 1.5.123, as long as the major version matches the major version of the SANE API it provides. There is actually quite a bit of misunderstanding of the use of version numbers in sane-backends but that's a long story. It involves package version, SANE API version, dynamic library versioning as well as backend versions. The problem is that people tend to assume it's all the same thing while in fact they are all very different and mostly independent.
