I have an OKI C5600 printer on my home network. The two computers
which connect to it run Windows 10 and XP. The most uptodate driver
available for the printer is Windows 8.1. It's printing of Windows 10
but won't accept anything from XP. I suspect the problem is a clash of
network security policies but so far I haven't been able to find any
user interface for this in W10. Frustrating.

Is the XP computer looking for the wrong printer IP address, because
it changed?
