-Because our print server has connections in two networks to serve broadcasts in these two networks, there are some routing glitches, when talking to the print server. The primary name of the server is "print-itp", which resolves to the IP address 141.2.247.27. To be able to broadcast packages to the laptop network, there is second address 10.63.255.9, which has the name "print-itp-63". This is the one you want to talk to.
