1. It is no problem when the scanner only reports one valid resolution
in the well known option

2. I have not seen a scanner that does not know the scanning resolution
before starting the scan. I think a backend should be able to find out
the resolution before starting the scan.
If not this may be a little problem, but I do not see a reason for this.
