[sane-devel] HP ScanJet 2400c

[carlos]

Hi Stef,
   I know how to program in C, but I know nothing about how a scanner works,
in any case, I have an hp2400c which has been doing a great job as a brick,
if you would be so kind so as to send me those scripts I may give it a try to 
write a backend for that scanner.
thanks,

carlos.
