Defining the printer to the host: TCP/IP attachment

F-14 Installation Planning Guide

NOTE: It is not necessary to define the printer in TCP/IP for MVS, because the printer acts as a conduit from the MVS system to the LAN. However, some settings in the TCP/IP Profile dataset may need to be altered, depending on your current settings.
