P713W printing problem

I am running Windows 10 on an Inspiron 7591 laptop linked wirelessly to a P713W printer.

It has suddenly stopped printing any Word or Excel documents.

Oddly, it still prints any internet docs and PDF files.

Why is this and how can I fix ?

I have tried the usual printer re-booting with no effect.

There doesn't seem to be a more recent driver available although I have reinstalled.

Any ideas ?
