How to share network printer w xp box?

On my old IBM Thinkpad running kubuntu Linux, I have an old HP LaserJet 4
Plus connected via a parallel port with "Share this printer" checked.
Please see this screen-shot:

This works fine as a network printer for my other Linux machines, but I
can't get it to work for my wife's laptop running xp.

Below are 4 screen-shots of what I see when I try to get my wife's xp to
use the HPLaserJet4 on my network.

Some other print driver options for the HP LaserJet 4 Plus are shown at

How can I find the ip address of the HP LaserJet 4 printer on my network?

Or, what else can I do to get this to work?
