Thanks for reviving the dead
I gave up and just have it as a network printer with Mrs B briefed on how to switch D Top on in her profile to print from the 'galley' on her L Top. I'll wait until I replace the printer to advance, I think. Amazing, isn't it, that a new printer with a set of ink carts (not 'full', of course) is, however, only a few £10's more than a set of carts alone.
