printer problem

[Richard Kimber]

I'm trying to set up a networked printer on a fresh install of
Ubuntu-Mate (18.04.1) on a new PC.

The printer is detected by the new printer install but after searching
for drivers, I get a cups server error  "server-error-internal-error".

The printer (Canon MX920 series) set up easily and worked perfectly well
on the old PC under 18.04.1 and previous versions of Ubuntu

I'd really appreciate some suggestions.
- Richard.
