Scanner not found with HP Photosmart B110 printer

[Frédéric PUPILLE]

Hello,

When using "Simple Scan" to use my scanner (included in my HP Photosmart B110 printer), it can't find any scanner.
The printer works properly, but not the included scanner.
It worked when I was using Ubuntu 14.04 operating system. It hasn't been working since I switched to Ubuntu 18.04.
I tried to fix the problem with HP procedure at: https://developers.hp.com/hp-linux-imaging-and-printing/install/install/index
At step 10, as my printer wasn't in the same room as my internet box, I chose "Restart", and not "Re-plug in".
So, I wasn't able to continue next steps (printer setup).
I looked for a solution on the same HP's site, found some "CUPS" configuration steps to perform.
The printer seems ok, but its scanner still doesn't work.

So, I ran "hp-check -t" and it gave:

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]

Very useful information, Frédéric It gives me a good idea of what is
going on. I'll explain in more detail later on. Meanwhile, see if you
can scan with

  simple-scan hpaio:/net/photosmart_b110_series?ip=192.168.1.75

I am assuming the IP address of the printer is still 192.168.1.75.

Would you also give what you get with

  avahi-browse -rt _ipp._tcp

and

  avahi-browse -rt _uscan._tcp

and

  scanimage -L

Cheers,

Brian.

There you are, except I suppose you want (quite reasonably) to
have *automatic* scanning by executing just 'simple-scan'. To
do this you have to play the game HPLIP's way.

From your previous information you have two print queues:

   HP_Photosmart_B110_series
   Photosmart_B110_series_7A3864_

They have URIs (matériels)

  dnssd://...
  ipp://...

There is nothing wrong with this for printing, but HPLIP requires
a printing URI beginning hp:/... for automatic scanning. So set
up a third print queue with

  lpadmin -p b110 -v URI -E -m PPD

URI is hp:/net/photosmart_b110_series?ip=192.168.1.75.
PPD is drv://hpcups.drv.hp-photosmart_b110_series.ppd.

Does simple-scan now work?

Before you set up the third queue would you execute 'simple-scan'
and then look at what 'journalctl' gives and report any error?
Also, give what you get for

  avahi-browse -rt _scanner._tcp

Brian.

[Frédéric PUPILLE (fredbsl)]

Hello,

Thanks for your answer and solutions.

You well saw the problem, I think, and you're right, I'd like to run simple-scan in automatic-mode, if possible ;-) .

About the existence of two print queues, it's that When I first installed my printer on Ubuntu 18.04, it was: Photosmart_B110_series_7A3864_
As I noticed the scanner didn't work, I tried several things without success.

So, a few days ago, I came on the HP site and tried a new installation (with "HPLIP"? I don't know yet the change). The new print queue was: HP_Photosmart_B110_series
So, I put it as "default print queue" and didn't cancel the old one until the new one works ;-) : Photosmart_B110_series_7A3864

But when all is ok, I will delete the old one.

By the way, there's a message now, on my computer, every time I boot it : I let you find the screenshot joined here, because I think it's linked with the printer/scanner issues.

I just tried :
lpadmin -p b110 -v hp:/net/photosmart_b110_series?ip=192.168.1.75 -E -m drv://hpcups.drv.hp-photosmart_b110_series.ppd

But obtained :
lpadmin : Unable to copy PPD file.

Maybe it's linked with the screenshot's message I joined?

Sorry, I tried the test of simple-scan after. Here below is the result in "journalctl":

Thanks for all the extra information, Frédéric. It is most useful.

The lpadmin command probably failed because I made a typo, The PPD
is

  drv:///hpcups.drv.hp-photosmart_b110_series.ppd

You should now be able to set up a third print queue. However, as
you will see, there is another technique to get automatic scanning
going.

This is the crucial clue:

> no tosmart_b110_series attributes found...

Note that "pho" has been chopped off. Then we have:

> no hp_tosmart_b110_series attributes found...

The three missing characters are replaced with "hp_". This doesn't
work either. You have experienced a longstanding HPLIP bug. See

 https://bugs.launchpad.net/hplip/+bug/1797501

Edit /usr/share/hplip/data/models/models.dat and copy the section
[photosmart_b110_series]. Change the header of the copied section
to [tosmart_b110_series]. You should now have automatic scanning.

Brian.

Hello Brian,

Thanks for your action.
The modification of "models.dat" file worked well.
The scanner works properly now.
I'm very gratefull to you.

About lpadmin, I didn't understand your "typo".
The PPD seems to be good : drv://hpcups.drv.hp-photosmart_b110_series.ppd
And it was what you told me to enter.

So:
lpadmin -p b110 -v hp:/net/photosmart_b110_series?ip=192.168.1.75 -E -m drv://hpcups.drv.hp-photosmart_b110_series.ppd

gave and still gives now:
lpadmin : Unable to copy PPD file.

But that's not a problem for me: The scanner works! ;-)

Bye and thanks again.

Frédéric

Splendid. It has been a delight to have worked with you, Frédéric.

> About lpadmin, I didn't understand your "typo".

Note the extra forward slash. drv:/// - not drv://.

Brian.
