Common problem....
USB printers ...... some have unique IDs actually built into the printer
(which appears to be the case in your problem.)..... if you install one and
then have to reconnect it to the second USB port, it will recognize that it
is the same printer, but you've just connected it to the other USB port....
XP will then realize this and 'transfer' over the drivers. If you connect a
second identical printer, but with a different ID, it will install a second
instance of the printer because, in XP's eyes, it is a different printer.
Some USB printers do not have the unique ID built it.... in which case if
you transfer the same printer to a second USB port, XP will automatically
install a second set of drivers, because again it thinks there is a second
instance of the printer.
You may be able to get around your problem by ensuing you use one USB port
for connecting the printer at work and another USB port when connecting the
printer at home. Otherwise, you're down to having two identical printers,
with unique IDs, therefore in XP's eyes, two different printers.
