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.
