simon- you have simply wonderful timing. i have spent all weekend making the next version of the updated backend. guess what scanner i used for the development- fi-5110C :)
after i have tested with the 4120c and 4120c2 that are here in the office, i will post another message to this list. stay tuned. allan On Mon, 1 May 2006, Simon Glass wrote: > Hi, > > I've just got one of these scanners.
