Package: hplip
Version: 3.16.11+repack0-3

I can not scan an image from a HP LaserJet M1120n MFP.
I am using the hplip package provided by debian( HP Linux Imaging and
Printing System (ver. 3.16.11))

Here is a transcript:

 Can we add support for this? Or am I doing something wrong? The same
command worked for this other printer: hp:/net/HP_LaserJet_3052

Info about my computer:
root@scanner:/# cat /etc/debian_version
9.4
root@scanner:/# uname -a
Linux scanner.docker.paul.grozav.info 4.9.0-8-amd64 #1 SMP Debian
4.9.110-3+deb9u4 (2018-08-21) x86_64 GNU/Linux

The machine runs inside docker:
pgrozav:~>docker version
Client:
 Version:           18.06.1-ce
 API version:       1.38
 Go version:        go1.10.3

I must say that the same problem occurs on the physical machine,
outside of docker. And I also have another container that is able to
scan from hp:/net/HP_LaserJet_3052 .

This is a message which involves the plugin.

 root@sid8:~# strings /usr/share/hplip/scan/plugins/bb_marvell-x86_32.so | grep 
get_msg
 bb_marvell.c 346: invalid get_msg tmo=%d total=%d uri=%s

My view is: whatever interaction is taking place between libsane-hpaio
(free) and the plugin (non-free), it is not one which can be attended to
by Debian.

https://bugs.launchpad.net/hplip

is the place to go.

Hence closing the report. Thank you for all your investigations. Sorry
it didn't work out.

Regards,

Brian.
