Bug#909250: HPLIP - scanner HP_LaserJet_M1120n

Hi, Brian,

Thank you for paying attention to this issue.

Since I'm running HP Linux Imaging and Printing System (ver. 3.16.11) I downloaded https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/hplip-3.16.11-plugin.run and then ran:

sh hplip-3.16.11-plugin.run --tar xf

python installPlugin.py

No errors so far. But i still get the same error when scanning with both commands:

hp-scan -d hpaio:/net/HP_LaserJet_M1120n_MFP?ip=192.168.200.16
scanimage -d hpaio:/net/HP_LaserJet_M1120n_MFP?ip=192.168.200.16 > image.pnm

Using the latest hplip plugin (3.18.9) didn't help either. I even tried to install hplip and hplip-plugin from HP, the latest versions(both 3.18.9), to avoid debian's repos. I still get the same error.

libsane-hpaio is installed, and the latest version(in debian's repos).

I saw that that folder you gave me contains a .plugin file: https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/hp_laserjet_m1120n_mfp.plugin that seems to be made for exactly this hp printer. Is there something special about this scanner device? should I use that file in any way?

I am starting to think that there might be a problem at a lower level. Every now and then I can receive an image from that scanner, but It's quite random, maybe 1 out of 100 attempts. I'm not sure, but it might be related to powering off and on the device from it's button. Is there something we can do to determine if the problem is on the device itself, or the client computer? The network cable between them seems to be fine, because I can access the printer/scanner through it's web interface(and printing works fine). Also, the device settings did not change in the last few years and I am getting an image every now and then. The only thing changing is the software and config on my client computer. That's why I started this thread.

Here's the network summary from that device:

Ok up to here.

Things go wrong!

Nothing to worry about. hp-scan will use hpscanxxx.png as the filename.

Looks worrying.

libm.so isn't on my i386 system and scanning with hp-scan works. It is
in libc6-dev and this package wouldn't normally be installed (because
it is a -dev). I don't know how significant the message is.

[Snipped. Printing isn't really relevant.]

I know nothing about Docker and containers

The only package needed to scan over the network is libsane-hpaio. You
could install it in a container without its recommended packages
(--no-install-recommends) and try

hp-scan -d hpaio:/net/HP_LaserJet_M1120n_MFP?ip=192.168.200.16

and

scanimage -d hpaio:/net/HP_LaserJet_M1120n_MFP?ip=192.168.200.16 > image.pnm

(Obtain the correct plugin from

https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/

Then

sh hplip-<version>-plugin.run --tar vxf

and

python installPlugin.py).

Brian.
