Show informational notification for network printers with XP firewall on

We have XPs firewall on and now users complain about the missing network
printing noticiation in the right corner. I can fix that doing one of two
things

1. I enable File and print-sharing for all computers (I can't just pick the
print server ?)
or
2. Add program spoolsv.exe but also there I have to apply to all computers
even those on internet (why can't I just add the print-server ? Not even the
whole 192.168.0.0/255.255.0.0 which are all my internal computers ???)

Neither of these alternative feels good. I want to restrict it to just my
printservers but then I can't get it to work.

Can you help me out ?

Sincerely
