Thanks. That's weird, though, as it's in the 4100 family and it has a 
perfectly fine USB connection... which works fine for CUPS printing and 
for Windoze scanning. Oh, you said "not yet", so there is hope that it 
might work over USB someday?

But I guess HP wants us to do everything over WiFi, whether we like it 
or not.

I'm working on this approach now (1.3.1). "Just a bit of configuration". 
Just this entry in escl.conf

$ scanimage -L
device `escl:http://192.168.43.160:443' is a HP DeskJet 4155e flatbed or 
ADF scanner

Any further guesses/help would be most appreciated.

Thanks!
