Allow access to just a shared printer

[Bill W]

I have a small 3 computer home network communicating over a wireless router.
One of the computers (XP) has a USB printer attached to it that is shared
with the other 2 computers. When we have guests at the house, they will
access the internet through the secured wireless router and at times have a
need to print. If possible, I would like to allow access to just the
printer and to none of the other shared folders, files or devices on our 3
computers. Is it possible to allow them access to just the printer? Thanks
for your help.

One point of clarification that might not be necessary - our guests are
accessing the internet through our secured router with their own personal
laptop - not through one of our computers. I would like them to access our
printer through their laptop and just the printer. Thanks again.
