You can use a cookie for this. But here's a suggestion - have a
password-protected admin page which sets the cookie. When they move the
computer, they have to log into the admin page and tell it which printer
to use.
This then sets the cookie, which is now available for the rest of your
pages. Of course, you would want to ensure that cookies are not cleared
when the browser shuts down - at least not for your site.
