what the other techs have posted will work but what i find is the easiest thing to do is.
1) go through the menu on your printer and find the settings for Netwok adapter address.
2) Once found assign an ip address that outside of the range used by DHCP. let me explain Let's say your router is issusing IP address from 192.168.1.100 -150 then in my notes I will use 192.168.1.90- 99 for Static IP address for printers or other networkable devices.
3) The Subnet Mask and the default gateway will be the same throughout the network.
Workstation setup.
There are two ways you can do this.
1) using the installation CD or downloaded drivers. This way the software will automatically detect the IP address of the printer and install it.
2) using Windows. Add printer (LOCAL PRINTER), add port (local TCP/IP port), enter the IP Address of the printer then select your printer type and drivers.
That complete the process.
P.S You must have administrative right to add printer port.
