Saving the IP Address in the Print Server
Print Server User Manual 23
Troubleshooting The 'Addition failed' error occurs when you use the 'arp' command.
This error informs you that the ARP table is empty and that the new
entry cannot be added. This problem occurs with certain operating
systems such as all Microsoft Windows versions with the exception
of NT 4.0. The solution to the problem is to ping a station in the
network before using the 'arp' command for the first time or use the
PRINTSERVER-NetTool to enter the IP address.
