It depends on the device you have and on whether using HPLIP
is a must.

Network or USB? The MFP M281fdw is a modern device and its scanning
function should be catered for on Ubuntu 20.04 by SANE without an HPLIP
scanner driver.. Please give the output of

  scanimage -L

Hi again, its networked,

scanimage -L

> Hi again, its networked,

Ideal. Thank you Sara.

sane-escl is the new sane backend I referred to earlier. I am not going
to attempt to debug either its behaviour or that of the HPLIP hpaio.
Instead, we will go to Plan B, which has worked for 100% of users who
have followed it.

Go to

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

and download and install the independent backend, sane-airscan. Here
is a direct link to the file (sane-airscan_0.99.8+66.1_amd64.deb) you need:

Splendid! sane-airscan keeps its 100% track record. :)

Sara, I am interested in what the URI for sane-airscan is. Please would you
post the output of 'scanimage -L' again.
