Thanks for your help.

I am not yet comfortable installing software from binaries so I will stay with
what is already installed on the laptop.

I ran scanimage -L on my laptop.

robert at MARS:~$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
robert at MARS:~$

Then I decided to run it on a desktop computer

bob1 at Juptier:~$ scanimage -L
device `hpaio:/net/hp_color_laserjet_mfp_m277dw?ip=192.168.60.153&queue=false'
is a Hewlett-Packard hp_color_laserjet_mfp_m277dw all-in-one
bob1 at Juptier:~$

I then ran sane-find-scanner.  It appears to only search for USB attached
scanners as the output was the same on both computers.

So from this it does not appear, to me, to be a simple-scan problem but an
Ubumtu configuration problem.

I borrowed an HP Envy 120 MFP from my son.  On the desktop computer scanimage
-L identifies both devices but my laptop can not find either of the devices. 
Also on the desktop computer simple-scan finds both devices but can only scan
from the HP Envy 120.  So there is a problem with simple scan and the HP M277.

For the time being I am not going to try to identify the problem with
simple-scan and the HP M277.

I do need to find out why my laptop can not find the scanners that are
connected wireless.

Now I am lost.  I have no idea on how to even begin to trouble shoot this kind
of a problem.
