Sorry I have not been back sooner.
A driver for XP appears to exist:
Thanks for that. For some reason I didn't find it.
However I have a bigger problem: the XP VM can see other devices, including other win7-64 computers, on the LAN, but it cannot see any printers attached to the Host machine. It cannot even browse files on it. It merely sees its name under Networks.
But the Host win7-64 machine can browse the VM.
I am using the Bridged LAN adapter option in the VM.
I tried lots of things... including dropping encryption from 128 bits to 56 bits. This is an internal LAN, behind NAT, anyway.
And other win7-64 machines cannot browse the VM filespace although they see its name under Networks.
I have spent so much time on this, over many years. Sometimes it is something under Local Policy...
Once the VM can see the shared 1061 printer (I've tried all kinds under its share options) then I will install that XP driver for it.
The printer is currently USB attached. Yes, as suggested, I might have better luck with ETH.
