Ahh, indeed, thanks!
Using Debian here, I see what you mean:
dpkg -L nmap|grep services
cat /usr/share/nmap/nmap-services|grep 9100
jetdirect 9100/tcp # HP JetDirect card
The printer I'm using here is a Minolta 2300DL,
so I guess it just happens to use the same port
number as the HP printers.
I hadn't thought much about which port was
being used, until after enabling guarddog,
and remembering that I'd just cut'n'pasted
the 9100 port number from an HP configuration
I'd used before.
