 Posted: Sun Aug 11, 2024 4:46 pm Post subject: Unable to scan over network witjh SANE server |
 |
|
I have an HP MFP that is supported great by HPLIP. I have a home server, and a laptop.
On the home server i have installed HPLIP, sane-backends and sane-frontends.
On the server i can find the scanner (and scanning works too):
| Code: |
server ~ # scanimage -L
device `hpaio:/net/hp_colorlaserjet_mfp_m178-m181?ip=10.70.43.27&queue=false' is a Hewlett-Packard hp_colorlaserjet_mfp_m178-m181 all-in-one
|
My sane.d is running and configured to allow my laptop.
On the laptop i have sane-backends and sane-frontends installed, i have configured sane to use the "net" backend and point to the server, but i cannot find any scanner.
On the client:
| Code: |
laptop ~ $ scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

On the server log i can see that the client connects and it's whitelisted:

( i have increased sane debug verbosity to the maximum level here)
So it seems that it's not a connection issue. Yet, no scanners are found.
I am at a loss. The Wiki doesn't help and i could not find much online.
Anybody has ideas?
thanks.
