Uh, you would have to unplug the usb cable each time, poor solution I agree.
Ok well the first thing you would need to do is to network both pc`s
and then probably would beable to share the printer (scan) between the pc`s.
Go here and take a look at these articles:

I hope this helps in resolving your questions and solutions to your
questions, I thought it better just to show you the articles instead of
trying to explain here and how to setup networking xp and vista together
then have the printer setup to file share on both windows as well as using
the hardware part of it also to send commands from both pc`s.
