Even after setting up my printer using the pre-installed HPLIP (using the command hp-setup), I couldn't scan (but I could print). Then it was mentioned that driver plug-in installation is required. When I try to install the driver plug-in, it simply doesn't install.

Then I used the terminal and typed the command hp-plugin. The output was:

So what exactly is the issue and how can I fix it?

I'm willing to provide any extra details. Also do read my post on Ask Ubuntu to have a better idea of my situation: https://askubuntu.com/q/1257349/1103140

No idea! My approach to a solution does not involve using HPLIP
or Python.

Get the device on the network with a wireless connection and give
what you get for

  avahi-browse -rt _ipp._tcp
  avahi-browse -rt _uscan._tcp

The LaserJet Pro MFP M126nw is an AirPrint printer and Bonjour is
generally enabled on it by default. Check and try

  avahi-browse -art

Thanks. I'll do printing first and move on to scanning after testing printing.

Set up a print queue:

 lpadmin -p m126 -v ipp://DEV4F70B4.local/ipp/print -E -m everywhere

Test with

  lp -d m126 /etc/nsswitch.conf

Good. Printing looks good. You may of course test with other applications such as
Firefox.

For scanning you need to download and install sane-airscan from

  https://github.com/alexpevzner/sane-airscan

The file you want is at

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

Give the outputs of

  scanimage -L
  airscan-discover

I tried printing from Firefox and it printed normally.

I installed sane-airscan by adding repository and installing manually.

This requires a plugin. Forget about it.

No plugin required. Can you scan with

  simple-scan "airscan:w1:HP HP LaserJet Pro MFP M126nw" ?

How about if you just start simple-scan and select from its dropdown
menu?

Or try

  scanimage -d "airscan:w1:HP HP LaserJet Pro MFP M126nw" > image.pnm

I am running out of decent ideas, Ramesh. Why should scanimage see

  airscan:w1:HP HP LaserJet Pro MFP M126nw

as an invalid argument when scanimage itself has provided it with the
-L option?

Comment out "hpaio" in /etc/sane.d/dll.d/hplip and re-plug the device
to the USB port. Try

 scanimage -d "airscan:w1:HP HP LaserJet Pro MFP M126nw" > image.pnm

again, and also

 scanimage -d "airscan:w1:HP LaserJet Pro MFP M126nw" > image.pnm

I don't why the outputs of some commands have changed.

Neither do I.

Apologies when I said previously

Forget about that. I forgot you were on the network with the M126mw!

As I said, I do not not know why the 'scanimage -L' has changed. Please
try

 scanimage -d "airscan:w1:HP HP LaserJet Pro MFP M126nw" > image.pnm

and

 scanimage -d "airscan:w1:HP LaserJet Pro MFP M126nw" > image.pnm

Should I do it?

It's not necessary.

We have printing going without a plugin. sane-airscan indicates that scanning
should happen using the WSD protocol with the URI

    airscan:w1:HP HP LaserJet Pro MFP M126nw

but this does not happen.

All I can suggest is that you raise an issue at

  https://github.com/alexpevzner/sane-airscan/issues

referring to this thread. How do you fell about that? Alex Pevzner is very approachable.

BTW, what about the HPLIP binary plugin? Is there any issue with the plugin? If yes, when will it be fixed? And also when is a the new HPLIP version releasing (which supports Ubuntu 20.04)?

Revision history for this message
brian_p (claremont102) said : 		#23

Ramesh - I cannot sensibly answer any of your questions. They
would have to be addressed by the HPLIP developers. The only
solution I know of for a misbehaving plugin is to download it from

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

and install with

  sh PLUGIN_FILE_NAME

Regards,

Brian.

I removed all my printers from the Settings app. Then downloaded hplip-3.20.3-plugin.run from https://developers.hp.com/hp-linux-imaging-and-printing/plugins
I ran the script and it was successful.

Then I typed hp-setup in terminal and added my printer.

Now printing and scanning both works :)
