This site is under construction
and should contain in a near future information on progress of hp5400 backend development.
Development planning is:
- get scanning logs for all kind of scan
- Write scan log tools for human reading of those huge files
- Understand communication protocol used here
- Write a testtool that can do a basic scan.
- Write a testtool that can do "complex" scan (setting position, color depth, resolution, etc..)
- Write a SANE backend.
HP5400 Protocol
