samba - Sep 2020 - Cannot access Windows 10 printer - but can access all other parts of teh server (disks, folders etc)

Hi,
 
I am very new to mailing lists so please excuse any mistakes I make
regarding ettiquete etc.

On a home network (Windows/Apple/Lunux) everybody has co-operated
happily. I recently swapped my Linux system from Mint (Mate) to Debian
(KDE) Buster.

I can no longer access the Windows machine's printer form Debian.
I have tried many things and done a great deal of googling but cannot
seem to find an answer. I have the following errors:-

As far as disk access goes, I can see and access all shared directories
in the Windows 10 machine but Samba (or something) has no knowledge of
the Windows printers.

I have spent a great deal of time on this and was hoping if no-one can
help me or indeed I am asking in the wrong place, perhaps someone could
point me in the right direction.

Thanking you in advance
