(Note - I've skipped this newsgroup for a while, so this might be a repeat
of something you've already read.)

I've only used giveio with NT and W2K, but I think XP is much the same.  You
don't have to do anything with the printer - when a program uses giveio to
access the parallel port, it simply walks all over any other program using
it - I freely mix a number of debuggers and hardware that uses the parallel
port (although obviously I only run one at a time).  But it sounds much more
like you don't have giveio installed, or you don't have it running - try
"net start giveio".
