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.
On this page you can find the first data on how the communication with the HP scanjet 5400 works.
On this second page you can find the list of messages used in the communication protocol and the tries to find their meanings.
