Depends on how it is connected on the LAN. Is it connected directly to Cat5 or Wifi network connection or is it shared through another computer on the LAN?
If its directly connected to the LAN you just need to know what the IP Address is of the printer and then manually install printer following this process:

Be sure to have the drivers ready on CD, DVD, or downloaded off the internet to associate with the printer you are installing, as for using the default drivers that Windows may associate with this printer might not work or might work with strange results. I like to use the drivers from the manufacturer and perform corporate driver install vs the full package with unnecessary features and services to my needs.
