[GTALUG] scanner on hp LaserJet Pro MFP M26nw

[Chris Aitken]

Hi. Just joined the group. I can't get scanner (on my hp LaserJet Pro 
MFP M26nw) working. It was scanning fine on my ubuntu 14.0-something LTS 
machine. However, I got a more powerful computer and had a fresh install 
of ubuntu 20.04.1 LTS done. I typed sane in a terminal and got..

Command 'sane' not found, did you mean:

   command 'save' from deb atfs (1.4pl6-14)
   command 'xsane' from deb xsane (0.999-8ubuntu2)
   command 'sage' from deb sagemath-common (9.0-1ubuntu4)
   command 'saned' from deb sane-utils (1.0.29-0ubuntu5.2)

Try: sudo apt install <deb name>

I tried sudo apt-get install sane and got ...

[sudo] password for owner:
Reading package lists... Done
Building dependency tree
Reading state information... Done
sane is already the newest version (1.0.14-15).
The following packages were automatically installed and are no longer 
required:
   hplip-data libimagequant0 printer-driver-postscript-hp python3-olefile
   python3-pil python3-renderpm python3-reportlab python3-reportlab-accel
Use 'sudo apt autoremove' to remove them.

0 upgraded, 0 newly installed, 0 to remove and 16 not upgraded.

So, I tried xsane and got ...

  Failed to load module "canberra-gtk-module"

Then an hp wizard offered to install it, then ...

  Failed to open device 
'hpaio:/usb_HP_LaserJet_Pro_MFP_M26nw?serial=CNB6J9P50R': Error during 
devioce I/O.

Printing is working fine.

Ideas?
