Followed The Hat's instructions but no-go.
Factory reset then uninstalled the printer.
Followed Peter's link to download the printer driver.
Downloaded the program and followed the instructions.
Could not find printer.
Tried via wi fi - same result.
I think the problem must be that it doesn't like working via the emulator. So should I be lucky enough to find a person who speaks English and is willing to lend me their pc (unlikely, as I've been here fifteen years and do not know of such a person) I will do as The Hat suggested and call it a day.
As it's today, I'll call it Thursday.
Many thanks to all of you for your kind and patient help.
