I've read the documents and the source code, so I'd like to start experimenting, but I have some questions: - is there a backend which could be used as starting point or it is better to start from scratch? - would it be possible to damage the scanner by sending some wrong commands? - are there licensing issues in using info desumed from the E3 Driver?
