You should really look in the manual of the printer. There's really no way to tell you without knowing what you have for a netbook, what kind of network, if any, you have, etc. If you have a wireless netbook connected to the internet through a router then just be sure the netbook has the updated HP drivers installed and the printer is set up for DHCP and it should grab the IP. Make sure the printer has the exact same password and encryption, WPA2 if possible, as the netbook. The same information you used to connect the netbook to your network. Or if it has a USB port just connect it directly to the netbook and set it up that way.
