Epson U220B - TM Two-color Dot-matrix Printer Technical Reference Manual page 46

TM printers are connected to a network via a hub using an Ethernet cable.
Note:
If the TM printer is connected to the host PC via an Ethernet interface, a DM-D cannot be connected to
the TM printer.
We provide the IP address setup utility"EPSON TMNet WinConfig," for setting the IP address of the
Ethernet model TM printer on the host PC. Please contact EPSON or your dealer about "EPSON TMNet
WinConfig" and the procedure for installing.
