These functions are built into Windows and are displayed as options when using the Add Printer 
Wizard.
Although there are some differences in configuration options between the 
various Windows platforms, the procedure for printing using TCP/IP is the 
same.
1. Ensure that the TCP/IP protocol has been installed in 
Windows. This can be confirmed by checking the network 
settings from within the Control Panel. If TCP/IP has not been 
installed refer to the section below Installation of TCP/IP 
protocol.
2. If not already configured, a suitable IP address, Subnet Mask 
and Gateway address should be configured. Please refer to 
the on-line help if necessary. It is vital that the IP address 
entered is unique and valid. Entering an incorrect IP address 
may cause severe network problems. Please check the 
address with the network administrator.
3. If your network environment uses domain names, DNS should 
be enabled and configured on your system. However, this step 
is not essential to enable network printing.
4. Restart the operating system.
