This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball
has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode
will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

4. A detailed explanation of your problem.

I am unable to use the scanner from Zorin Linux. Document Scanner recognizes the scanner is there but is unable to scan. Under some conditions the scanner is scanning (audible) but the data is not sent to the computer. I have tried many many things to fix it but nothing has worked. I have tried removing HPLIP, installing different versions of HPLIP, and USB connection, and Ethernet connection, and BOTH connections. In some conditions Document Scanner says "Plug-in required" and it asks if I would like to download it from HP, and I say yes, and it says "Unable to detect network" even though my Ethernet connection is active. On the HPLIP website I cannot find a way to download the plug-in required for the scanner.

5. Steps to recreate the problem.

(a) Install Zorin OS 16.1 core and turn computer ON

(b) Connect the printer by USB or Ethernet or both, and turn printer ON

(c) Run Document Scanner

(d) Select printer

(e) Select SCAN

(f) Shake head in disappointment

Thanks for your help.
I assumed those were console commands, but they are getting rejected by my
system:

jim@EliteZorin:~$ avahi-browse -rt_ipp._tcp
avahi-browse: invalid option -- '_'

jim@EliteZorin:~$ avahi-browse -rt_uscan._tcp
avahi-browse: invalid option -- '_'

jim@EliteZorin:~$ avahi-browse -rt-ipp.-tcp
avahi-browse: invalid option -- '-'

I tried a few variations with 'dash' and 'underscore' but none worked.
avahi-browse man page didn't help, but that may be my lack of familiarity
with this.

What do you suggest?

Jim K.

Thanks for the info. Sorry for the typos. Thanks Manfred.

You have a printer that provides AirPrint v1.4. Download and install
sane-airscan from

  https://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04/amd64/

For USB you will need ipp-usb too.

Ubuntu 22.04 has these packages as standard; a future Zorin will
have them too.

Now, please give

  scanimage -l
  airscan-discover

airsan-discover has discovered that the M130fn understands the eSCL
and WSD protocols. eSCL is expected because there is an output from
'avahi-browse -rt _uscan._tcp'.

Therefore 'scanimage -L' should show a device beginning with 'airscan:e0... .
But it doesn't!

At the same time 'scanimage -L' has 'device `escl:http://169.254.250.136:8080'.
escl is a SANE backend that also uses the eSCL protocol. Why this but not an
entry for the airscan backend?

Let's revert to the HPLIP plugin route. Download the plugin run file for your
HPLIP version from

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

Then do

 sh plugin_file

How does that go?

Back to sane-airscan. Find the [options] section in /etc/sane.d/airscan.conf
and add 'protocol = manual' to it. Run 'scanimage -L'. I am only interested
in whether airscan is in the output.

As to the hplip plug-in, the version of hplip that I have installed is what
is available in the Zorin software catalog. The source is snapcraft.io,
and the version is 1.0. In your download plug-in link I don't see a plugin
link for this version. I could remove that version and do an apt install
and see what version I get that way...
When I try to scan from Document Scanner, it says "you need a plug-in" and
when I choose "download from HP", it says "Network connection not
detected", and there is no path forward.
Thanks for your help. I hope it is of some use to you to see what is going
on here, and that it will in the end benefit others. BTW - I worked for HP
for 50 years.

I am unfamiliar with Zorin and am basing my advice on what I
know about Ubuntu 20.04. I also do not know where snapcraft.io
fits into the picture. The HPLIP version being used should be
given by

  dpkg -l hplip

Can you scan with

  simple-scan "airscan:e0:HP LaserJet MFP M130fn (C1F054)"
or
  simple-scan "airscan:w1:HP LaserJet MFP M130fn (C1F054)" ?

simple-scan (which is the same as Document Scanner) may be
replaced with xsane.

Brian --
You made my head nod.
simple-scan "airscan:w1:HP LaserJet MFP M130fn (C1F054)"
The above WORKS. Scans, copies to computer, saves image.

*There are other things that work now*. The Gui version of simple-scan
"Document Scanner" now finds FIVE different scanners.
1. WSD HP LaserJet MFP M130fn (C14054) works !
2. eSCL HP LaserJet MFP M130fn (C1F054) works !
3. ESCL HP LaserJet MFP M130fn (C1F054) does *not* work
4. HP HP_LaserJet_MFP_M129-M134 does *not* work - (can't get plug-in)
HP hp_laserjet_mfp_m129-m134 does not work - (can't get plug-in)

Note: I think there was a re-boot in between my last tests reported to you
and the above tests. Maybe that change to that .conf file wasn't active in
 previous tests. Both USB and Ethernet are connected to the MFP.

My last request would be for a suggestion on what I can put in my notes
under "What to do if the scanner stops working." Also it would be helpful
if you can describe what was wrong before. And also, since I can PRINT
without hplip, is it now the case that I don't need hplip at all? (I
don't use FAX.)
Thanks very much for all your effort on this.
--Jim K.
P.S. Zorin OS 16.1 is just Ubuntu with a different DE and maybe different
software included. There is a free version and a $35 version that comes
with staff support. I have the free version.

Splendid! I reckon that is sufficient to mark this issue as solved.

Probably a bug in SANE's escl backend. The entry may function
when Zorin updates to Ubuntu 22.04.

The HP entries are not really of any use to you without a plugin.
They could be dispensed with by doing

  sudo apt purge libsane-hpaio

Actually, as you correctly deduce, you don't need any of hplip at all.
An updated Zorin will also update sane-airscan and ipp-usb.

I do not know what was wrong before, but one wonders whether the
printer's firmware is bug-free. See my next post. To help with your
notes read about IPP-over-USB, eSCL and WSD at

Hello Jim,

Something is bothering me. You have

> 2. eSCL HP LaserJet MFP M130fn (C1F054) works !

That would be expected because there is a _uscan._tcp service
provided by the M130fn and, indeed, the airscan backend is
making use of it to give what is above.

However, you also have

> "simple-scan "airscan:e0:HP LaserJet MFP M130fn (C1F054)" does NOT work.

There is a double quote (") before the s of simple-scan. It should
not be there. Did you type this as part of the command? If not and

  simple-scan "airscan:e0:HP LaserJet MFP M130fn (C1F054)"

still does not work, it is unexpected because the command does
exactly the same as the Gui version of simple-scan. Please check
again and try

  xsane "airscan:e0:HP LaserJet MFP M130fn (C1F054)"

Good catch --
The following DOES work.
simple-scan "airscan:e0:HP LaserJet MFP M130fn (C1F054)"
I must have included the extra double quote as you suggest.
Do you think that the change we made to airscan.conf is what fixed this
problem?
That seems to be the only change I made to the system, except that I ran
several diagnostics . Is there any downside to leaving that change in
place, if it is not what fixed the problem?
I will check out the references you gave in your last email, save all of
your emails, and I'll go to launchpad and confirm the issue is resolved.
Thanks again.

The change allows you to have entries to use eSCL or WSD for scanning.
Normally it is sufficient to have eSCL only, so try reverting the change.
However, there shouldn't be any downside to leaving it in place as far as
being able to scan is concerned.

Thanks for your engagement.
